Diet to reduce phosphorus in the blood when taking phosphate binders

Phosphorus role in the body, tests, its deficiency and excess

Phosphorus (P) is a microelement essential for the full functioning of the body. It plays a fundamental role in the formation of bone tissue, normalization of acid-base balance and helps maintain energy balance. Phosphorus is present in the body in the form of various compounds called phosphates. Phosphorus in the blood is contained in the form of inorganic compounds. Approximately 85% of its volume is part of the skeleton. The remaining 15% of the trace element present in the body is stored in various tissues and biological fluids.

Phosphorus is translated from Greek as “carrying light.” This name is due to the unique glow properties of white phosphorus in nature. It is worth noting that in nature phosphorus does not exist autonomously, since it has high chemical activity, creating various compounds with other elements.

Phosphorus was first discussed back in the 17th century, when a Hamburg alchemist named Henning Brant managed to isolate this substance from human urine. This happened in 1669. It is noteworthy that the purpose of the experiments was not to discover the qualitative composition of urine, but to attempt to isolate gold from it in pursuit of the creation of the mythical philosopher's stone. By the end of the 19th century, the understanding of the nature of phosphorus and its properties expanded significantly, and the stage of active study of this microelement as a substance indispensable for the functioning of the human body began.

Macronutrient that provides energy to the body

The largest amount of phosphorus is concentrated in bone tissue, and this is about 600 g, which is 85% of the total amount of the element present in the body. The remaining 15% P is distributed in different proportions in fluids and other tissues of the human body. Phosphorus is not classified as an ultra - (mass fraction from 10x(-5)% and below), nor as a microelement, the limits of which range from 10x(-3)% to 10x(-5)%, its content in the body approaches 0.5 - 1%, and this is slightly more than 10x(-2)%, which allows us to classify it as a macronutrient. Moreover, very significant.

If the content (lower limit of normal) of this element drops by half (the norm of phosphorus in the blood of an adult is 0.65 - 1.30 mmol/l), then it is no longer enough to fully provide the body with energy resources, which is why the energy exchange in cells. In addition, phosphorus performs other important functions, for example, it is involved in maintaining blood pH (phosphate buffer system).

Phosphorus analysis is carried out together with the following studies

Calcium and phosphorus in the blood are responsible for the strength of our bones and teeth

But it is important that the values of these elements not only correspond to the norm, but also are in the correct relationship with each other. So, according to various sources, there should be one and a half or even two times more calcium than phosphorus

A blood test will help identify this.

To determine the level of this element in the blood, a simple blood test is taken from a vein in adults, and from the heel in small children. On the eve of the procedure, you should avoid taking antacids, diuretics and laxatives, as they can distort the test results. Blood collection must be carried out on an empty stomach in the first half of the day (from 8 am to 12 noon).

The last meal should be no later than eight hours before the test. Before the analysis, you should not specifically consume foods rich in this element, as this may increase the concentration of phosphorus in the blood. You can only drink regular purified water, not mineral water. By following these recommendations, you can get a reliable picture of the state of the body.

What is the research used for?

To diagnose various pathological conditions that cause disturbances in phosphorus-calcium metabolism and monitor their treatment (together with checking the level of calcium, parathyroid hormone and/or vitamin D).

As an additional study for hypo- or hypercalcemia (since a moderate deficiency or excess of phosphorus may not appear).
For symptoms of kidney and/or gastrointestinal pathology.
Regularly, when pathological conditions have already been diagnosed that cause significant changes in the level of phosphorus and/or calcium (to monitor the effectiveness of their treatment).
For diabetes mellitus or signs of acid-base imbalance.

Low phosphorus: causes and signs

Alcohol intake impairs phosphorus absorption

The development of hypophosphatemia is caused by insufficient levels of elements necessary for the absorption of P. For example, a deficiency in protein in the diet is accompanied by a decrease in the level of P in the blood. Constant consumption of alcohol provokes the development of chronic R deficiency. Microelement malabsorption occurs in various malabsorption syndromes.

Increased loss of P in the urine is the result of diseases of the endocrine system, when the synthesis of parathyroid hormone exceeds the physiological need. Another reason is excessive dosage of diuretics.

A decrease in P concentration in the blood is accompanied by a disturbance in the acid-base balance, when alkali compounds accumulate in the body. An excess of certain elements leads to the development of phosphorus deficiency, primarily calcium, as well as aluminum and magnesium.

Muscle weakness may be a sign of hypophosphatemia

The movement of P compounds from the extracellular space into cells occurs during intensive treatment of diabetic ketoacidosis, resumption of normal nutrition after prolonged malnutrition, recovery after removal of the parathyroid glands, and respiratory alkalosis.

Acute hypophosphatemia occurs with alcohol intoxication, extensive burns, increased ventilation of the lungs, and in the postoperative period.

A mild form of P deficiency usually does not manifest itself clinically; with a significant decrease in P concentration in the blood, muscle weakness, bone pain, and convulsions are felt. Symptoms of liver dysfunction, pathological fractures, softening and deformation of skeletal bones are observed.

Treatment and prevention of high phosphate levels

Treatment of elevated phosphorus levels in the blood is based, first of all, on eliminating the cause of the deviation. Therapy depends on the pathology of the organs that caused the change in the concentration of the macroelement in the serum.

With hyperphosphatemia during an exacerbation period, there may be a need for emergency therapy, for example, hemodialysis for tumor collapse syndrome.

For endocrine disorders, therapy consists of hormonal correction. In patients with renal failure, the mainstay of treatment is reducing dietary phosphorus intake.

Such patients are prescribed a low-protein diet and phosphate binders. Patients with end-stage kidney disease are prescribed calcium carbonate.

Patients on dialysis are recommended to take Sevelamer. The drug binds phosphates in the digestive tract, reducing their concentration in the blood serum.

Treatment of hyperphosphatemia is carried out strictly under the supervision of a physician. Self-medication can significantly worsen the patient’s condition and lead to serious complications.

With hyperphosphatemia, diet becomes an obligatory component of complex therapy and prevention of pathology.

Foods high in protein are excluded from the patient's diet: dairy and meat products, nuts, etc. The intake of medications containing phosphates, vitamin D and calcium is also controlled.

General recommendations for the treatment and prevention of elevated phosphorus levels include giving up bad habits, taking multivitamin complexes, and moderate physical activity.

An increase in the concentration of phosphorus in the blood is a reason to consult a doctor to draw up a specific therapy plan.

Timely treatment allows you to eliminate the symptoms of the pathology in the shortest possible time and eliminate the development of complications.

We often heard in childhood that we need to eat fish, it contains useful phosphorus. And only as we grew up, we learned how important this microelement is for the human body.

Firstly, phosphorus is concentrated to a greater extent in our bones and teeth in conjunction with calcium; it is these two elements that make bone tissue mechanically strong, while correctly forming its structure. In addition, phosphorus is essential for the body to produce energy, which means we can move, think and simply live. Phosphorus compounds are present or somehow involved in almost all cells of the body, as well as in physiological, chemical and metabolic processes in the body.

The role of this element in the body should not be underestimated, because without it all kinds of vital processes of movement, thinking, contraction, breathing, etc. will simply be impossible.

A test to determine the level of phosphorus in the blood is usually prescribed to patients if there is a suspicion of kidney or bone disease, if it is necessary to find a problem with the parathyroid glands or cardiac activity.

Let's talk in more detail about this indicator, and consider what the norm of phosphorus in the blood of a healthy person should be.

Causes of hypophosphatemia - mechanisms

Logically, it can be assumed that the first cause of phosphorus deficiency is its insufficient intake from food, or insufficient absorption in the intestines. The second standard mechanism is increased renal excretion. Finally, the third mechanism is the transport of phosphorus from the blood to the tissues, that is, from the extracellular space to the intracellular space. Let's look at when this happens in more detail.

Receipt deficit

This reason is the most rare. The fact is that phosphates are very well absorbed in the intestines, they are found in various forms in foods, and even in a dietary diet, phosphates are most often very well represented in the diet. Almost always, the daily need for this mineral is guaranteed to be met.

However, it should be taken into account that if the body’s need for phosphorus suddenly increases, and a person has a chronic absorption deficiency in the intestine, for example, malabsorption, and the diet in relation to phosphorus is quite deficient, then secondary nutritional hypophosphatemia may develop. This can be facilitated by the abuse of heartburn medications that contain large amounts of magnesium, aluminum or calcium, called antacids. In addition, for complete absorption of phosphorus in the intestine, a large amount of vitamin D is necessary, and in the case of vitamin D deficiency, the absorption of phosphorus may also be impaired.

Increased loss

Perhaps this situation occurs most often. And this does not always mean that the kidneys are sick, and they pass the phosphorus needed by the body into the urine:

Most often, this is hyperparathyroidism, or excessive production of parathyroid hormone by the parathyroid glands, which causes phosphorus from the renal tubules not to be absorbed back into the blood, but to be released into the urine;
If the patient drinks a lot of salty liquid, then phosphorus is lost in large quantities, since the so-called salt diuresis inhibits its absorption in the tubules;
There are congenital genetic abnormalities associated with rickets and liver dysfunction, such as Fanconi syndrome and Wilson's disease. They can cause phosphate depletion.

Let us list which diseases and conditions cause low phosphorus in the blood.

Causes of phosphorus loss - diseases

There are quite a lot of such diseases, and the older the patient and the more severe the condition, the higher the risk of phosphorus loss:

in older people - this is the uncontrolled prescription of diuretics, especially for edema;
in chronic alcoholism, especially in combination with exhaustion and frequent vomiting, when there is additional nutritional hypophosphatemia;
in the presence of burn disease. In this case, excessive loss of electrolytes from the burn surface causes not only phosphorus loss, but also numerous other electrolyte disturbances;
with the development of diabetic ketoacidosis, with type 1 diabetes, when the metabolism of carbohydrates increases, and there is not enough energy in the form of ATP for catabolism;
for disorders of the thyroid gland;
with low potassium concentration in blood plasma;
with high insulin levels (hyperinsulinism). This hormone utilizes glucose into cells from the blood, but since this process is energy dependent, it is impossible without phosphates (ATP). If a patient has a high level of insulin in the blood, then a competent doctor will definitely check the blood for phosphorus;
severe vomiting and diarrhea;
chronic hereditary diseases of the liver and copper metabolism (Wilson-Konovalov disease, or hepatocerebral dystrophy).

But in these conditions, symptoms of hypophosphatemia are sometimes not always visible or suspected. Acute loss of phosphorus, which manifests itself with specific symptoms, develops in acute alcohol poisoning, in severe burn disease, against the background of a sudden intake of a large amount of food into the body after a long period of malnutrition, and also if the patient is on artificial, parenteral nutrition for a long time.

But chronic, sluggish hypophosphatemia includes various endocrine pathologies, hyperparathyroidism, and long-term use of diuretics. How does phosphorus deficiency manifest clinically in acute and chronic form?

Why does phosphorus decrease?

A low level of a trace element in a person’s blood is hypophosphatemia. This phenomenon may be a sign of poor nutrition, anorexia, or lack of vitamin D. A low concentration of a microelement in a person’s blood can be caused by a number of diseases and pathological processes, but in most cases this phenomenon is associated with excessive consumption of alcoholic beverages, in addition, it often occurs in people having drug addiction. Other reasons for the decline are as follows:

rickets;
severe vomiting or diarrhea, dehydration;
gout;
pregnancy;
malignant tumors;
hypercalcemia.

In young children who have not yet turned one year old, a decrease in phosphorus can be caused by an incorrectly selected formula for feeding when the body has not yet adapted.

The main symptoms are fatigue, problems with the musculoskeletal system, muscle pain, persistent illnesses of acute respiratory viral infections, acute respiratory infections, and impaired concentration.

In the absence of bad habits and serious illnesses, low phosphorus levels can be caused by poor nutrition, in which a person does not receive the required amount of the microelement from food. In this case, the concentration of phosphorus can be increased to normal levels by changing the diet

But it is important to understand that this can be done in childhood or adulthood. For people 60 years of age and older, nutrition alone will not be enough to raise microelement levels.

How to normalize the amount of phosphorus in the blood?

If the level of phosphorus in the blood is low, its concentration can be raised to normal levels with the help of a proper diet that increases the amount of the microelement. Your daily diet should include whole grains and protein-rich foods. You can increase the phosphorus content by taking dietary supplements.

Dietary supplements have a number of contraindications if taken in excess, so they can be introduced into the diet only after consultation with a doctor. The dose and course of administration depend on the general condition of the patient, the level of phosphorus in the body and the presence of concomitant diseases.

If high or low levels of a microelement are caused by various diseases, it is necessary first of all to treat them along with dietary adjustments. Taking dietary supplements along with medications should be discussed with your doctor, as serious side effects may occur.

Excessive consumption of phosphorus can lead to an imbalance between this trace element and calcium. And this, in turn, is fraught with the occurrence of bone diseases, which is often expressed in damage to dental tissue, bleeding gums and the development of osteoporosis.

Correction of phosphorus levels: diet and medication correction

If such signs are detected, a study is recommended

When correcting the P level, the cause of the pathology is first identified in order to eliminate it. During therapy, regular monitoring of P and calcium levels in the blood is performed.

With hyperphosphatemia, the consumption of food containing a high concentration of P is limited: dairy, meat, fish products. Drugs that bind P compounds are prescribed. The choice of drug depends on the concomitant disease and condition of the patient. Effective aluminum-based preparations are used with extreme caution in cases of renal failure or are replaced with calcium acetate and carbonate. If there is a risk of developing hypercalcemia, calcium-free products are used, for example, allylamine hydrochloride polymer. A course of diuretics is prescribed for normal renal function, and dialysis for end-stage renal failure.

For hypophosphatemia, foods rich in P are introduced into the diet: tuna, salmon, sardines, shrimp, crabs, milk and dairy products, chicken eggs, pork and beef, mushrooms, pumpkin seeds, legumes, nuts. The prescription of drug treatment depends on the level of P in the blood, the duration of the deficiency and the cause of its formation. Products containing P, sodium and potassium are often prescribed. All medications that contain elements that bind compounds P, as well as diuretics, are discontinued. If the factor causing P deficiency is a lack of vitamin D, drugs based on it are used.

Phosphorus in products

Almost all products contain phosphorus. But the greatest amount of phosphorus is found in products of animal origin. These include meat, fish and poultry, as well as eggs, milk and yoghurts, cheeses prepared on their basis. Entering the body with food, this microelement is mostly absorbed in the form of inorganic compounds. It is noteworthy that phosphorus obtained from animal products is absorbed much more easily than the trace element contained in plant foods.

In terms of quantity, the most phosphorus is contained in dry yeast. Here there are 1290 mg of phosphorus per 100 g of product. Approximately the same amount of microelement is found in wheat bran, pumpkin seeds and a number of other plant products. The second largest amount of phosphorus contained are dairy products. Thus, 100 g of cheese contains approximately 600 mg of microelements. This indicator may vary depending on the type of cheese. Together with 100 g of cottage cheese, the body receives 500 mg of phosphorus, with kefir - 140 mg, and with milk 90 mg. It is worth noting that including dairy products in your daily diet is the best solution, since in addition to phosphorus they contain a large amount of calcium. The third place in terms of quantitative phosphorus content is occupied by fish and seafood. Fish contains a high percentage of phosphorus, calcium, and iron.

As mentioned earlier, phosphorus is found in almost all food products that fill the human daily diet. You can consume up to 5000 mg of this microelement per day without harm to your health.

It is important to take into account that once the substance enters the body, it is not completely absorbed:

The body receives the most phosphorus from dairy products;
approximately 60-70% of the microelement comes from eating meat and seafood;
Of the total phosphorus content in plant foods, only about 20% is absorbed by the body.

When compiling your diet, it is necessary to take into account not only the presence of a sufficient amount of phosphorus in it. Don't forget about calcium

It is important that the amount of calcium entering the body does not exceed the amount of phosphorus. To ensure that the body receives calcium and phosphorus in the optimal amount, you need to choose the right foods for your diet.

The ideal solution is to include fatty cottage cheese, hazelnuts, beets, carrots, and cabbage in the daily menu. Beef liver, walnuts, beans, oatmeal, buckwheat and wheat porridge, as well as black caviar are excellent sources of phosphorus for the body.

The food industry today also actively uses phosphorus. Many of its compounds make it possible to give products a more attractive appearance. Phosphates, for example, are used in sausage production. With their help, manufacturers bind excess liquid in products, ensuring their uniform structure, density and juiciness. The use of phosphates is relevant in the production of canned meat and fish, factory-made butter, margarine, processed cheese and everything that is certainly included in the diet of every modern person. Using various phosphorus compounds, manufacturers can:

replace acidifiers in sweet sodas, low-alcohol drinks and confectionery products with phosphates;
avoid the formation of hard crystals in condensed milk;
eliminate the possibility of lumps forming in powder additives such as milk powder, cocoa, cream, etc.;
achieve a uniform soft consistency when producing processed cheese curds;
accelerate the dissolution of dry mixtures in the production of ice cream and other such products;
increase the preservation of margarine and butter;
increase the density of canned vegetables and fruits;
clarify sugar, etc.

Phosphorus is found in excessive quantities in modern industrial products. And this can cause significant harm to health. Normally, the amount of phosphorus and calcium entering the body should be approximately the same. The maximum allowable intake is 1.5 parts P and 1 part Ca. To avoid consuming excessive amounts of phosphorus, the composition of products must be studied very carefully.

In this case, special attention should be paid to the presence in the composition:

orthophosphoric (phosphoric) acid, designated by code E338;
sodium phosphates – E339;
potassium phosphates, presented as additive E340;
calcium phosphates, indicated on labels as E341;
ammonium phosphates – E342;
and, finally, magnesium phosphates under the code E343.

Clinic and treatment

Experienced doctors know that, unlike acute loss of phosphorus, chronic signs are usually quite weak. But in some cases, young patients with short stature, with crooked legs, may suffer from hereditary phosphorus deficiency, and in adult patients, a characteristic sign of chronic deficiency of this mineral may be pain in the bones of the arms and legs when palpated.

Acute and severe loss of phosphorus most often manifests itself as muscle pain, signs of heart failure, since there is a deficiency of ATP as an energy molecule for myocardial contraction.

Respiratory failure develops because the diaphragm, as the main respiratory muscle, becomes very tired, again due to ATP deficiency. This critical concentration of phosphorus in the blood plasma approximately corresponds to 0.32 mmol/l, after which cardiac output begins to rapidly decrease with the appearance of signs of congestive heart failure.

In the event that there was a chronic loss of phosphorus for a long time before the acute loss of phosphorus, necrosis and disintegration of striated muscle tissue, or signs of rhabdomyolysis, may result. The patient experiences focal neurological symptoms, convulsions, cardiac arrhythmia appears, the phenomenon of hemolysis is observed in the blood, and liver function decreases.

As clinical practice shows, most often such conditions develop in people with disabilities, who often suffer from septic and bacterial infections, as well as with intensive overfeeding after chronic malnutrition. In patients with epilepsy, such severe forms of loss of this mineral result from the use of valproate, and all these conditions require careful monitoring of serum phosphate levels.

How to treat such dangerous and quickly occurring muscle weakness, heart failure, convulsive syndrome and coma? This is the introduction of phosphates - PO4.

But before prescribing such replacement therapy, it is very important to find and eliminate the causes that caused this condition. Phosphates are introduced into the body in all ways: but depending on the clinical case.

This may include intravenous phosphate, oral medications, or dietary phosphate, where the patient is placed on a phosphorus-enriched diet.

Intravenous administration

Intravenous administration is, first of all, severe and acute hypophosphatemia, when the patient has cardiopulmonary failure and severe muscle weakness. Indications for intravenous phosphate administration are severe hypophosphatemia, less than 0.16 millimol/l, with seizures, coma, symptoms of rhabdomyolysis, or focal neurological symptoms. Usually a mixture of phosphate and potassium hydrogen phosphate is administered, but only if renal function is preserved.

If it is impaired, then it is necessary to use sodium phosphate, and within 6 hours of administration it is necessary that the body receives no more than 0.08 mmol/l, otherwise there may be complications. During such replacement therapy, it is imperative to check the concentration of phosphorus and calcium in the blood serum and monitor the patient, because with a high rate of phosphorus administration, the calcium concentration in the blood will drop.

Tablets and Dietary Phosphate

We are usually talking about sodium phosphate or potassium phosphate, but in some cases, such drugs are poorly tolerated by patients, as they can cause diarrhea, so you should try as much as possible to adhere to the principles of naturalness, and give milk instead of drugs.

Every day an adult under normal conditions needs 1 g of phosphorus. Usually, if an adult drinks a liter of cow's milk every day, the body's needs for phosphorus are fully satisfied. It is important that dairy products are additionally supplied with calcium, and this makes it possible, when introducing phosphorus into the body, not to cause an antagonistic drop in calcium in the blood plasma.

Now we know what it is - hypophosphatemia. This is a rather insidious condition, which can be expected in the serious condition of a patient hospitalized in a hospital for somatic pathology, or in the intensive care unit. But it is much easier not to guess, but for all patients to monitor blood plasma electrolytes, gas composition, as well as indicators of acid-base status. This will allow, in many cases, to quickly take the necessary measures to correct metabolic disorders, and even avoid the development of multiple organ failure.

What are the causes of increased phosphorus levels?

Phosphorus is an essential macroelement that participates in almost all processes and ensures normal human life.

Phosphorus, present in the human body as organic and inorganic compounds, is responsible for the uninterrupted functioning of the central nervous system, muscle function, respiration and fermentation processes.

Phosphorus makes up most of the bone skeleton. In addition, the transmission of nerve impulses, cell growth and division, and metabolism are impossible without the participation of phosphates.

The macroelement is in balance with calcium, the ideal proportion of the two elements is 2 to 1. It is this combination that is responsible for the integrity of the teeth and their resistance to mechanical stress.

Phosphates regulate the absorption of many substances, such as vitamin D and glucose. The macroelement is responsible for metabolism and cellular energy metabolism, promotes the rapid and efficient production of carbohydrates and proteins.

The many aspects and areas of phosphorus functioning explain the importance of the macronutrient content in the human body. Normally, phosphorus in the blood is in the range of 0.87 – 1.45 mmol/l

At the same time, children and older people have their own limits, and deviations from standard values in this case are acceptable and are associated with changes in hormonal levels.

Causes of high levels of phosphorus in the blood include, first of all, following a diet with large amounts of the element.

This situation is possible if there are a lot of protein dishes in the diet. Excessive consumption of canned foods and carbonated drinks can also increase the level of phosphate in the blood.

Since phosphorus is involved in many metabolic processes, its level will increase in liver pathologies (for example, cirrhosis) and impaired kidney function (including Addison's disease).

Hyperphosphatemia is often observed in cancer patients, and the condition most often occurs in patients with blood and lung cancers.

Sometimes high levels of a macronutrient are temporary. For example, a deviation from the norm to a greater extent is typical for pregnant women in the first trimester and is associated with early toxicosis.

The same picture is observed during the healing of bone fractures. At the end of the process, the phosphorus concentration returns to normal values.

Long-term contact with organophosphorus substances can increase the amount of phosphates in the blood. Gardeners and agricultural workers are at risk, since these compounds are contained in high doses in fertilizers.

In addition, military personnel exposed to chemical warfare agents may suffer from high levels of phosphorus in the blood.

High performance

This phenomenon may have various reasons. An increased level of phosphorus in the blood (over 1.45 mmol/l) is called hyperphosphatemia. This means that the component accumulates in various organs, especially in bone tissue, which leads to disruption of the kidneys, heart, and nervous system. Convulsions also occur.

What are the causes of increased phosphorus in the blood? This phenomenon may be due to:

renal failure, due to which there was an incomplete removal of phosphates from the body;
hypoparathyroidism;
anemia;
development of various tumors;
destruction of muscle cells or bone healing during fractures;
osteoporosis;
excess vitamin D;
deviation in the functioning of the heart muscle;
regular contact with this component (gardeners and agricultural workers often use phosphate fertilizers, as well as military personnel who use hazardous chemicals).

So, the main causes of increased phosphorus in the blood include:

lack of calcium;
renal dysfunction;
insufficient bowel function.

This phenomenon occurs in both adults and children. This can be determined by the following symptoms:

joint pain;
brittle bones;
kidney stone disease;
reduced iron content;
fatigue and fatigue;
body aches;
low levels of leukocytes in the blood.

If these signs occur, you should visit a doctor. The specialist will identify the reasons. Increased inorganic phosphorus in the blood can be due to various factors, but in any case it is necessary to normalize it, which only a doctor can help do.

Interaction of phosphorus with other substances

The content and absorption of phosphorus in the body largely depends on the functioning of the thyroid gland and the parathyroid glands located near it, as well as on the functions of the kidneys. Thus, the thyroid gland synthesizes the hormone calcitonin, and the parathyroid glands produce parathyroid hormone, which have a hypophosphatemic effect on the body. In addition, vitamin D is of great importance for the metabolism of phosphorus compounds called phosphates. Calcitriol, a derivative of vitamin D3, has a hyperphosphatemic effect.

One of the most important is the relationship between phosphorus and calcium. Both microelements form insoluble compounds necessary for the formation of bone tissue and are involved in other vital physiological processes. Phosphorus is also the main microelement that ensures the complete absorption of vitamin B3. Thus, it is of great importance for ensuring the normal functioning of the kidneys and heart, saturating cells with oxygen, generating and distributing energy, transmitting nerve impulses and performing basic metabolic processes.

The effectiveness of phosphorus is lost with excessive intake of iron, aluminum and magnesium. At the same time, excess phosphorus disrupts the absorption of magnesium, contributing to the development of migraines, arrhythmias and other disorders of various systems.

The level of phosphorus is regulated through the interaction of parathyroid hormone and vitamin D. This “tandem” ensures the absorption of the microelement in the intestine, its transport from bone tissue and processing in the kidneys. The metabolism of phosphorus can be disrupted due to pathological processes in the parathyroid glands, bone tissue and kidneys.

Prevention of deviations from the norm

A balanced diet is a component of prevention

The level of P in the body depends on a number of elements, especially calcium. To achieve the optimal concentration of P, it is recommended to maintain a phosphorus-calcium ratio in food products of 1.5: 1. A necessary component for maintaining normal phosphorus concentration is vitamin D. At the same time, an overdose of vitamin has the same negative effect on the P content as its deficiency. Consuming a balanced amount of protein, fat and carbohydrates is integral to optimizing your body's phosphorus levels.

Prevention includes timely detection and treatment of diseases leading to deviations in P levels. First of all, changes in the number of phosphorus compounds are affected by pathologies of the kidneys and thyroid gland.

Excess and deficiency of phosphates

Any deviation from the norm - both a lack and an excess of phosphorus in the blood - is an important signal about a malfunction of the body.

A significantly reduced level of the element is called hypophosphatemia.

Among the main symptoms of low phosphate concentrations are:

fatigue, feeling of weakness;
muscle pain;
frequent colds;
myocardial dystrophy;
increased bone fragility.

Often the phosphorus deficiency state is physiological, for example, in children who are bottle-fed.

A decrease in the level of macronutrients in the blood is observed within several hours after vomiting and diarrhea or when taking diuretics and laxatives.

Patients on certain diets that are low in protein (meat products) may suffer from macronutrient deficiency.

This risk also occurs with a diet that includes foods rich in calcium, magnesium, aluminum and barium.

Any metabolic failures, pathological conditions of the thyroid gland and kidneys, diabetes mellitus lead to a decrease in the concentration of the element in the blood. Drug addicts and alcoholics are at risk for phosphate levels.

Hyperphosphatemia - an increase in phosphorus in the blood - manifests itself:

urolithiasis;
anemia of various etiologies;
leukopenia;
bleeding;
liver and gastrointestinal diseases;
active destruction of bones (for example, brittle teeth).

Elevated levels of plasma phosphate are thought to be a consequence of high-protein diets and consumption of foods with excessive amounts of preservatives. Vitamin D deficiency and nutrient metabolism pathologies lead to an excess of the macronutrient in the blood.

A high concentration of phosphates is observed during the healing of fractures, during toxicosis of pregnant women in the first trimester, and upon contact with organophosphorus substances (such as, for example, agricultural fertilizers).

To determine the causes of illness in the presence of symptoms of hyper- or hypophosphatemia, the doctor will prescribe a test for the concentration of phosphorus in the blood.

The research procedure is simple: in the morning, before meals, blood is taken from a vein (in newborns - from the heel), which is then studied using the colorimetric method, and the amount of the macroelement in the plasma is determined.

It is recommended to take the test in conjunction with calcium testing.

The results of the test can be distorted by food intake before blood donation and many medications (including insulin and oral contraceptives).

Phosphorus is an important element responsible for various processes in the human body.

Deviation from its normal content always becomes a signal of a malfunction in the functioning of internal organs and should be eliminated only under the supervision of a doctor based on tests and examinations.

How to take the test: preparation

Diagnosis of indicators can be carried out in a simple way, using blood sampling. A blood phosphorus test shows the level of inorganic phosphorus. It changes throughout the day under the influence of certain factors, so to obtain the most accurate and objective data you need to follow simple recommendations.

Important. Blood sampling takes place in the very morning (from 8 to 11 o’clock), strictly on an empty stomach. It is important to limit food intake 8 hours before the test, do not have a large dinner the day before, and avoid heavy, difficult-to-digest foods. You are allowed to drink plain water.

Blood is taken from a vein; in very young children, blood is taken from the heel. Analysis of the results should only be carried out by a doctor; it is also advisable to conduct a blood test for other indicators to obtain a clearer picture.

General concept of matter

The functions of phosphorus can be represented as follows:

By combining with calcium, it gives bones strength. The ratio of both elements should be 70/30 or 75/25, more for calcium: if the proportion is violated, then the bone tissue remains hard, but at the same time becomes brittle.
With the participation of the element, the phospholipid layer of any membrane is formed.
The reaction of the body to obtain energy is impossible without the substance, since ATP is adenosine triphosphoric acid.

Free molecules of the substance are rare: it quickly comes into contact with other substances and is transported further as part of compounds. The inorganic compound is released by several liquids:

The level of phosphorus in the blood is in the range of 0.81-1.45 mmol/l; this is the fraction soluble in the blood. In addition to this compound, there is also an insoluble part in the composition of membranes and immune compounds. Joints contain phosphorus in the form of calcium salts.
Phosphates are excreted along with urine at a rate of 16-64 mmol/day.

It is necessary to know the peculiarities of meaning in people of different ages and the factors influencing the turnover of the element.

Why is phosphorus needed?

First of all, phosphorus and phosphates are one and the same thing, and when it comes to assessing the amount of phosphorus in the blood plasma, they determine, first of all, inorganic phosphorus compounds, or inorganic phosphate. Our body needs this mineral for:

Bone tissue growth;
Participation in the functioning of the nervous system;
Performing muscle contractile function;
Phosphates are buffer compounds and maintain acid-base balance in the blood.

But its main role is energy production. Everyone knows a compound that is an energy donor - ATP, or adenosine triphosphoric acid. All energy-consuming processes, such as transmembrane transport against a concentration gradient, require the presence of ATP.

Phosphorus enters our body only with food. Then it binds with calcium, and almost 80% of the resulting substance passes into the tissue of bones and teeth. However, 1/10 of all phosphorus is needed by muscle tissue, and 1% by nervous tissue. All other phosphorus is a substrate for energy synthesis, while 1% of all phosphorus in the body is constantly in the blood plasma.

Sources of this mineral include fish, eggs, vegetable oil, green peas and beans.

Phosphorus is excreted by the kidneys, and the human body constantly maintains the concentration of this substance at the desired level by controlling its absorption in the intestines and excretion by the kidneys. Read more in our article Phosphorus in the blood.

The main regulators of phosphorus in the body are the parathyroid glands, and their hormone is parathyroid hormone. The level of plasma phosphates depends on the concentration of vitamin D3 and calcium. These connections are interconnected. So, if calcium in the blood plasma decreases, then phosphorus, on the contrary, increases. If, on the contrary, any of these minerals is in excess in the blood, then the other is excreted in the urine more than required. Calcium and phosphorus can be considered to be antagonists.

When does a doctor prescribe a blood test for phosphorus and phosphates?

Prevention of normal phosphorus levels

Maintaining normal levels of macronutrients in the blood is necessary for everyone, and especially for people suffering from kidney failure. Control is possible independently without the daily supervision of doctors. The main thing is to know with what products it enters our body and reacts, either by reducing or increasing its absorption.

It is very important to include dairy products in your daily diet. They are rich in animal proteins

People suffering from kidney failure try to reduce their meat consumption. In this case, it must be replaced with animal proteins from dairy products. But it should be remembered that it has a large amount of phosphorus and it is necessary to use drugs that bind phosphorus when eating dairy foods.

But it should be remembered that it has a large amount of phosphorus and it is necessary to use drugs that bind phosphorus when eating dairy foods.

In case of kidney diseases, all dairy products should be included in the diet only after consultation with a nutritionist. There are also dairy products with low phosphorus content - soft cheeses. It is also necessary to eat hard, aged cheeses. They are very rich in phosphorus, calcium and protein. Milk is a food that is rich in phosphorus and should be consumed in moderation. The same applies to fermented baked milk, kefir and various starter cultures. Do not forget about products containing milk as one of the ingredients. This includes cocoa, hot chocolate, and, of course, ice cream. When consuming these products, you must carefully monitor the time and, if necessary, be sure to take medications that bind phosphorus (calcium acetate, sivilamer, almagel).

Every trace element that enters our body affects it both positively and negatively.

It is very important to maintain balance. After 40 years, try to eat more green lettuce, spinach and all kinds of vegetables

If possible, reduce heavy meat foods, alternate vegetables with dairy products and, of course, see a nutritionist

What does a urine test for phosphorus show?

During the day, a healthy person loses from 0.42 to 2.2 grams of inorganic phosphorus in the urine, which is from 13.5 to 70.0 mmol of the element. For the upcoming analysis, daily urine is collected (for 24 hours), but for the test itself, only 20 ml of the entire volume is taken.

The reasons that cause an increase in the excretion of phosphorus from the body, as a rule, are hidden behind some pathology that cannot be called insignificant:

Rickets (a lot of phosphorus in the urine - its amount in sick children can increase up to 10 times);
Increased secretion of parathyroid hormone (primary hyperparathyroidism);
Primary tumors of bone tissue and metastases from other organs, causing bone destruction (osteolysis);
Phosphaturia of both renal (kidney transplantation, cellular acidosis and impaired functional abilities of the proximal tubules) and extrarenal origin.

A decrease in the amount of the released element may be due to trivial reasons, for example, a deficiency of phosphorus in the diet. Or it may have a serious pathology:

Decreased function of the parathyroid glands;
Intestinal malabsorption in chronic enterocolitis or due to hereditary pathology;
Vitamin D-intestinal rickets;
Kidney failure;
Increased production of somatotropic hormone (in an adult).

Increased phosphorus in the blood causes, symptoms, what does it mean

Phosphorus is a macroelement necessary for human life. It is involved in the transmission of nerve impulses, is responsible for the growth and strength of the bone skeleton, and helps metabolism at the cellular level.

Attention! The norm of phosphorus in the blood is 0.81-1.45 mmol/l. Deviation from normal values is dangerous for the life and health of the patient

If phosphorus in the blood is elevated, a thorough examination is necessary. An increase in phosphorus can be a sign of kidney and liver pathologies, cancer, and phosphate poisoning.

Hyperphosphatemia is often observed in cancer patients, and the condition most often occurs in patients with blood and lung cancers.

In addition, military personnel exposed to chemical warfare agents may suffer from high levels of phosphorus in the blood.

Foods high in protein are excluded from the patient's diet: dairy and meat products, nuts, etc. The intake of medications containing phosphates, vitamin D and calcium is also controlled.

General recommendations for the treatment and prevention of elevated phosphorus levels include giving up bad habits, taking multivitamin complexes, and moderate physical activity.

An increase in the concentration of phosphorus in the blood is a reason to consult a doctor to draw up a specific therapy plan.

Timely treatment allows you to eliminate the symptoms of the pathology in the shortest possible time and eliminate the development of complications.

fine

We often heard in childhood that we need to eat fish, it contains useful phosphorus. And only as we grew up, we learned how important this microelement is for the human body.

In addition, phosphorus is essential for the body to produce energy, which means we can move, think and simply live.

Phosphorus compounds are present or somehow involved in almost all cells of the body, as well as in physiological, chemical and metabolic processes in the body.

The role of this element in the body should not be underestimated, because without it all kinds of vital processes of movement, thinking, contraction, breathing, etc. will simply be impossible.

Let's talk in more detail about this indicator, and consider what the norm of phosphorus in the blood of a healthy person should be.

The normal level of phosphorus in the blood

It is necessary to monitor standard phosphorus indicators to find out whether there are deviations in one direction or the other. In both cases, it is necessary to take measures to normalize and stabilize the level of the indicator.

It is necessary to take into account that the standard values are indicated for the average person with a measured lifestyle, therefore, when assessing the results, the doctor must take into account whether the patient has individual characteristics of the body: is he subject to increased stress, has chronic diseases or disorders, etc.

On average, the level of phosphorus in the blood is considered normal if it is within the following limits:

For newborns - 1.19-2.91 mmol/l;
For children under 12 years old - 1.45-1.78 mmol/l;
For adults - 0.81-1.45 mmol/l.

It should be noted that the rate of phosphorus in the blood of women during pregnancy or breastfeeding should increase, due to the fact that these periods are characterized by a physiological lack of the mineral in the body.

When inorganic phosphorus in the blood is below normal, the reasons can be varied, but the main ones can be identified: drug addiction, alcoholism, gout, rickets, pathological conditions of the parathyroid glands, malabsorption of substances in the intestine. In newborn babies, a decrease in phosphorus levels may be associated with incorrect selection of formula for artificial feeding, which does not fully meet the baby’s needs.

How to normalize an indicator

How is the level adjusted? If there are significant deviations of phosphorus from the norm, unfortunately, you cannot do without taking medications that the doctor will prescribe based on the test data.

But in general, for the health of every person, it is necessary to eat foods that contain a lot of phosphorus; this mineral is best absorbed in products of plant origin, for example: bran, wheat sprouts, pumpkin and sunflower seeds, nuts, cashews, almonds, yeast. Also rich in P are liver, eggs, cheeses and red fish (trout, salmon, pink salmon).

Carefully. It should be borne in mind that a lot of phosphorus is found in sausages, carbonated drinks, ice cream, etc. A person who constantly eats such harmful foods receives an excess of the mineral several times over. This can be dangerous, so it's worth sticking to a healthier and healthier diet.

If an increased or decreased level of phosphorus is associated with some concomitant diseases, then first of all it is necessary to treat these diseases . People should also avoid unfavorable factors , such as excessive contact with phosphate fertilizers or chemical warfare agents, and at the first sign of a change in the level of this macroelement in the blood, stop completely.

Causes of increased phosphorus levels

Hyperphosphatemia is a condition in which there is excessive levels of a substance in the body. The causes of hyperphosphatemia in most cases are quite serious. If phosphorus in the blood is elevated, this indicates that the following pathological conditions may be present:

diseases leading to the destruction of bone tissue - the main ones are cancerous bone lesions - metastases, sarcoidosis, bone tuberculosis and leukemia;
cirrhosis of the liver;
osteoporosis;
insufficiency of functioning of the parathyroid glands;
excess vitamin D in the body;
acidosis;
acute renal failure;
chronic renal failure.

If a blood test taken for phosphorus shows its excess, the person may be prescribed additional examinations to identify the cause of the pathology and prescribe appropriate therapy

An increase in phosphorus in the blood is almost never without cause, therefore, when a disorder is detected, it is very important to undergo a full examination

In cats

In animals, exceeding the norm of components also leads to various ailments. Increased phosphorus in the blood of a cat - what does this mean? The norm in these animals is 1-2.3 mmol/l, and its increase will be an excess. Increased phosphorus in the blood of a cat leads to chronic renal failure, nephrosclerosis, hydronephrosis, tuberculosis, polycystic disease, and kidney tumors. But a reduced level is also possible, which is a symptom of rickets.

Phosphorus is considered an important element. Its excess or deficiency causes adverse consequences that lead to changes in the functioning of various organs. Often illnesses lead to deviations from the norm, therefore, for various disorders, a comprehensive examination and identification of the root cause is required. In order for the level of the component in the body to be in the required quantity, you should consume more plant foods and eliminate harmful chemically produced foods.

Consequences

With pronounced disturbances in the phosphorus balance, the immune system weakens and the full functioning of organs and systems is disrupted.

Possible risks

Hyperphosphatemia	Hypophosphatemia
Intestinal and liver dysfunction, kidney stones, atherosclerosis, heart attack, stroke, anemia (anemia), tooth decay, osteoporosis, bone fractures	Rickets in children and adults, hyperesthesia (decreased sensory perception), psycho-emotional instability, slowed brain activity

What products does it contain?

The most accessible and safe way to increase the amount of phosphorus consumed is to review your diet. The following foods are rich in this macronutrient:

fish;
processed cheeses;
feta cheese;
mustard;
almond;
pistachios;
hazelnut;
garlic;
beans;
oat and barley groats;
sour cream and cream;
cottage cheese.

Natural and synthetic vitamins containing phosphorus are also useful, but they should be taken with caution and under the supervision of a doctor, as they may not combine well with other medications. It is almost impossible to cause an excess of this macronutrient in the body with a balanced diet. As a rule, exceeding the norm of phosphorus in the blood is associated with pathological conditions in the body. The quantitative value of this element can be determined clinically.

How is the level of the substance in the body regulated?

To slightly increase or decrease the phosphorus content, you need to choose the right diet.

It is advisable to include the following products in your diet:

Soft cheese, processed.
Sea fish.
Seafood, especially shrimp, crabs, squid.
Oat, wheat or rice bran.
Pumpkin, sunflower or squash seeds.
Dairy products.
