What can tell the total blood protein: the norm, the reasons for its decrease and increase. Increased protein in the blood: causes. Blood chemistry. Total Protein Why Protein Increases

Blood protein is represented by albumins and globulins. If the function of the latter is mainly associated with immunological reactions, then albumins perform a wide variety of tasks: they maintain blood viscosity and fluidity, acid-base balance, constant temperature circulating blood. In addition, fractional proteins carry out the transfer of steroid hormones and other important substances.

In the course of a biochemical blood test, both the total protein and its individual components can be determined - albumins and their content by fractions, globulins and their class composition. It is worth noting that such an indicator as total blood protein, although it is an integral part of the analysis, is a large diagnostic value does not carry in itself.

In newborns - 43-76 g / l;
In children 1-5 years old - 60-74 g / l;
From 5 to 15 years - 51-77 g / l;
In adults - 64-83 g / l.

Reasons for increasing total protein

An increase in the level of total protein in the blood is a rather rare phenomenon due to the fact that its causes are usually very serious. It should also be noted that the increase can be absolute, when the amount of plasma proteins increases without changing the volume of circulating blood, and relative, which is associated with blood clotting.

A relative increase in total protein is noted with:

Diarrhea and debilitating vomiting, which are accompanied by exicosis, and as a result, a decrease in the amount of fluid in the whole body;
Intestinal obstruction, causing an obstacle to the absorption of water from the digestive tract;
Cholera, which is characterized by increased blood viscosity
Acute bleeding can also provoke an increase in protein due to significant fluid loss.

The reasons for the absolute increase in protein in the blood are even more serious:

Malignant tumors that have their own, perverted metabolism and intensively producing proteins;
Autoimmune diseases such as rheumatoid arthritis and lupus erythematosus, in which the body's immune system becomes aggressive against its own healthy cells and tissues;
Chronic course of infectious and inflammatory processes, in which protein enters the blood from destroyed tissues;
Sepsis.

An increase in the level of total protein in the blood cannot be accidental and is always associated with a threat to the patient's life. Therefore, when hyperproteinemia is detected in externally healthy people an analysis of protein fractions and a number of studies are prescribed.

Decreased protein in the blood

The reasons for a decrease in the level of protein in the blood are more common than the reasons for its increase. Hypoproteinemia can also be absolute and relative, and the second occurs only when a person consumes too much water - the so-called "water poisoning". In principle, the detection of hydremia suggests an increase in thirst, which is an integral symptom diabetes and diabetes insipidus.

The absolute decrease in the level of protein in the blood can be due to many factors:

Dieting and fasting, causing a low intake of protein in the body;
Narrowing of the esophagus, gastritis and other diseases that can reduce a person's intake of protein foods. In addition, in some cases, with diseases of the stomach and duodenum note a violation of the production of pepsin, which breaks down proteins into simple peptide chains and amino acids. Of course, this affects the absorption and absorption of protein;
Liver diseases - hepatitis, cholecystitis, cirrhosis, carcinomas. Any disease of the liver reduces the production of bile - the most important part of the digestive juice, which leads to poor absorption of proteins. In addition, a significant part of blood albumin is synthesized directly in the parenchyma of this organ;
Increased protein breakdown, which can be observed with prolonged fever, a significant increase in body temperature, as well as with extensive burns and frostbite.
High physical activity without making the necessary adjustments to the diet can also lead to a decrease in plasma protein;
Exudative inflammation, in which a significant part of the proteins comes out with the fluid - exudate. Much less often, the loss of blood protein can also occur with the release of transudate during the formation of edema and dropsy;
Kidney diseases in which protein is excreted in the urine - pyelonephritis, nephrosis and some others.

An increase and decrease in total blood protein is not specific sign any disease, but allows to judge the presence of chronic or acute pathological processes in the body.

Blood test for total protein is undeniably important, since protein is responsible for many functions in the human body, namely:

responsible for the ability of blood to coagulate and for its fluidity;
sets the volume of blood in the vessels;
responsible for the transfer of vital substances through the blood vessels (these substances include fats, hormones, and other compounds);
responsible for the stability of the blood pH; supports protective functions organism.

Total blood protein includes albumins and globulins. Albumin is mainly produced in the liver, while globulins are synthesized by lymphocytes.

Blood protein should be determined in cases where the following diseases are suspected:

any disorders associated with reduced immunity ( infectious diseases, various systemic disorders)
collagenosis
kidney and liver disorders
neoplasms
thermal burns
anorexia, bulimia

In order to determine the amount of protein in the blood, it is necessary to pass the analysis strictly on an empty stomach in the morning. The norm is a protein level of 66-88 g / l for an adult and children over 14 years old. For children under 1 year old, the protein norm is 44-73 g / l, for children 1-2 years old - 56-75 g / l, for children 2-14 years old, this figure ranges from 60 to 80 g / l.

Protein deficiency may be seen in the blood physiological changes in the body, i.e. during pregnancy and breastfeeding, during long immobilization, as well as in children under 7 years of age. Reduced level protein in the blood is called hypoproteinemia . A relative decrease in the level of protein in the blood usually occurs when the volume of blood in the system increases.

An absolute lack of protein in the blood can be a sign of the following diseases:

limited intake of proteins from food. This happens with starvation, diets, rejection of protein foods, various functional disorders digestive system(pancreatitis and others), with prolonged inflammatory diseases intestines and other diseases accompanied by a decrease in the digestibility of proteins;
various liver diseases that lead to impaired protein synthesis;
extensive burns, persistent bleeding, chronic disorders kidneys also lead to a decrease in the level of protein in the blood, since under these conditions the body intensively loses protein;
protein breaks down with prolonged overheating of the body, thermal burns, cancers, increased training and other loads, as well as with hyperfunction thyroid gland(thyrotoxicosis);
in the case when the protein goes beyond the vessel bed;
water poisoning (too much water in the body).

Increased protein is rare and is a sign of the following pathologies:

autoimmune diseases, such as autoimmune thyroiditis;
acute infections;
chronic infections;
lack of water in the body;
malignant tumors with excessive production of harmful proteins.

An elevated level of protein in the blood is medically called hyperproteinemia .

When deciphering a blood test, it must be taken into account that excess or insufficient protein can be caused by taking certain medications, such as corticosteroids and estrogen-containing drugs ( oral contraceptives and others). It is also important to consider what time of day the analysis was taken. It is not for nothing that blood sampling is recommended to be done in the morning, because at night the level of protein in the blood changes slightly. Another factor to remember is in what position the patient was taken. The protein level always rises if the patient is lying down and standing up abruptly. If the tourniquet was applied too tightly to the arm during blood sampling, this can compress the vessels and cause an increase in protein levels.

Only a doctor can correctly decipher the result of a blood test, so if the protein is increased or decreased, the patient should contact the attending physician or family doctor. Even if the deviation from the norm is insignificant, you should immediately consult a specialist in order to prevent deterioration of the condition and to identify the pathology in time, if any. The protein level outside the norm is amenable to drug correction, after which it is necessary to retake a blood test to determine the effectiveness of the therapy.

A huge number of different compounds constantly circulate in human blood. These are ions, neutral molecules, active elements in combination with transport molecules, and finally, a large number of a variety of proteins. In total, there are about 5 million varieties of different proteins in the human body, but in everyday routine laboratory practice it is quite enough to study the number and changes of about 200 compounds of this nature. If you remove the liquid part of the blood, or plasma, and evaporate all the water out of it, then the total protein will be about 7% by weight. In the composition of the total protein, the most important components are albumins and globulins.

What does high blood protein mean?

The very first way to assess protein status is a biochemical blood test for total protein. When studying the level of total protein, we are not talking about any specific fraction. And if the protein in the blood is increased or decreased, then we are talking about changes in the quantitative composition of this general mixture.

After all, total protein is nothing more than the total sum of all types of whey proteins, the number of varieties of which reaches hundreds. In the structure of the analysis, there is no difference between albumins and globulins, which means that it is impossible to give detailed information about the types of compounds based on the results of this analysis. However, the concentration of total protein without a detailed division into fractions can tell about some conditions of the body. Why is it so?

Serum proteins maintain oncotic pressure and prevent the penetration of the liquid part of the blood plasma into tissues, preventing edema from developing. Accordingly, proteins keep the volume of blood in the vascular bed. Protein buffer system maintains acid-base balance, participates in clotting factors and fibrinogen in coagulation processes, determining the biochemistry of hemostasis.

Proteins perform numerous transport functions. Without these molecules, it is impossible to transport fatty acids, sex hormones and thyroid hormones, ions such as copper, calcium and iron through the blood. Compounds that are poorly soluble in water, which include certain types of vitamins, also require protein transport systems.

In addition, numerous globulins, which are also part of the total protein, take part in immune reactions, are antibodies and are part of the complement system. The vast majority of these proteins are produced in the liver, and antibodies are synthesized by plasma cells.

Let us dwell on one question: if the protein in the blood is elevated, is it good or bad? As a rule, a decrease in the amount of protein or hypoproteinemia causes concern. People without medical education for some reason, they believe that if there are a lot of erythrocytes and protein in the blood, then this is good, because “in general, it’s good when there are a lot of everything.” This is not true. Hyperproteinemia, that is, a condition when there is an excess of protein in the blood, is no less dangerous than its decrease. Let's consider for what reasons hyperproteinemia, or an increase in total protein in the blood plasma, may occur.

Causes of hyperproteinemia

In the case when there are few plasma proteins, the reasons are more or less clear. The body "falls short" by synthesizing fewer proteins than it needs. The liver may be affected, there may be a lack of immune forces in the body, and plasma cells begin to synthesize less antibodies. It is clear that there will be a shortage of proteins during starvation. And under what conditions will there be an increase in protein in the body, the synthesis of fractions in excess? When does increased content protein in the blood that is outside the reference values?

About absolute and relative values

First of all, hyperproteinemia, or increased total plasma protein, can be either relative or absolute. What does it mean? Let us explain the concept of absolute and relative increase or decrease in the amount of something by simple example. We have a bowl in which peas (protein) float in water (blood). If we add peas, then we can assume that the concentration of peas has increased (true hyperproteinemia). On the other hand, you can drain the water, and as a result it turns out that the concentration of peas has increased again, since there are more peas in the same volume, as in the first case. But in fact, its number has not changed. In the first case, we are talking about absolute value, and in the second - about the relative.

Physiological and pathological hyperproteinemia

What does relative hyperproteinemia indicate? It may not be caused by excess protein synthesis, but by a decrease in the amount of water or blood plasma in which this protein is found. Most often, this is profuse sweating, or pronounced hemoconcentration, or thickening of the blood with a significant loss of fluid. Profuse sweating is physiological mechanism, and therefore increased protein can occur in hot climates, when crossing the desert, and is more common in men. But this will increase not only the concentration of total protein. There will be a change, and the total ratio of formed elements to the liquid part of the blood will increase, since with the loss of water, you can calculate according to any of chemical compounds and for any of the types of blood cells.

As for pathological relative hyperproteinemia, there are many diseases and conditions that lead to severe dehydration. First of all, they are sharp intestinal infections and especially cholera.

With cholera, a person can lose tens of liters of water throughout the day, which causes such a pronounced thickening of the blood that it coagulates in the vessels. Also, fluid loss can be significant with uncontrollable vomiting.

High protein occurs at a variety of autoimmune diseases. This is a whole group of pathological conditions in which the body constantly produces antibodies to its own tissues, and they are called autoantibodies. Therefore, during exacerbation of autoimmune processes, in patients with rheumatoid arthritis, systemic lupus erythematosus, ankylosing spondylitis, systemic scleroderma, the amount of total protein in plasma can significantly increase. If, however, a more thorough examination is carried out, it turns out that the amount of albumin in this patient does not change, and the entire increase in proteins occurs due to an increase in the synthesis of gamma globulins, or specific autoantibodies.

There is a whole group of special malignant diseases in which cells that have undergone regeneration do not form metastases, multiplying uncontrollably, but begin to synthesize abnormal, harmful proteins in very large quantities, which increase the result of the analysis. These proteins are called paraproteins. The most famous example of such a disease is multiple myeloma, which is called paraproteinemia. The second example of such a pathological condition is Waldenström's macroglobulinemia. These pathological proteins can increase the overall rate quite significantly.

In some cases, long-term chronic infections can cause an increase in total blood protein due to the production of normal antibodies that successfully block and bind antigens and microbial toxins.

Sometimes the total plasma protein rises with massive destruction of red blood cells or with. In this case, hemoglobin, most of which is globin, will be released into the blood plasma, and is defined as an increased protein concentration. After all, this analysis is not able to distinguish at what expense the faction managed to “raise” the value of the analysis. But in this case, very quickly with the help of other studies it turns out that hemolysis has occurred.

If we recall that most plasma proteins are produced by the liver, then with some of its diseases, increased production of various protein compounds is possible. This is a process characteristic of special types of active chronic hepatitis, including autoimmune, and is a nonspecific reaction of hepatocytes to inflammatory process. However, this does not last long, and after inhibition of hepatocyte function, hyperproteinemia can be replaced by its opposite. Such a change indicates the development of liver failure.

A rather rare cause, when an increased protein in the blood is determined, may be a violation of the function of the adrenal cortex, and a disorder of water-salt metabolism. In this case, again, we will talk about relative hypoproteinemia associated with periodic fluid deficiency in the bloodstream.

Do not forget that with some errors, when the patient takes the test after a recent meal, the amount of total protein can be increased. This functional hyperproteinemia can also be caused by the use of some medicines, drinking alcohol, coffee, and fatty foods on the eve of the study.

When conducting a specialist Special attention refer to total protein content. Any deviation from normative indicators may be a sign of different hidden diseases occurring in the human body.

Protein is a kind of indicator of health, and its decrease may indicate malfunctions in the functioning of organs and systems. What is the name of the condition when the total protein in the blood is lowered, what pathologies does such a violation signal, and how can such an indicator be normalized?

It is considered a building material that is simply necessary for all organs and systems of the human body. As a scaffold, it forms the basis on which all cells and molecular structures of other types of metabolism are subsequently attached. In other words, protein is the main building material, without which it is simply impossible to restore the structure of cells and tissues.

Serum total protein is the concentration and globulin of the liquid component of the blood. The constituent elements of protein and protein functions are complex amino acids. Proteins are actively involved in various biochemical processes occurring in the human body. In addition, they serve to transport such nutrients like lipids and minerals.

Proteins are a kind of catalysts, and it is they who own the immune function of the body.

The total protein helps to maintain a constant pH of the blood circulating in the body and is actively involved in the coagulation system. Due to the presence of protein in the human body, all constituent components of the blood are contained in the serum in a suspended state.

According to the indicators of the total protein, we can talk about the state, because thanks to this element, the blood has such characteristics as fluidity and viscosity. Thanks to such qualitative characteristics of the blood, the heart and the whole the cardiovascular system generally. Most often, with pathologies, the concentration of protein in the blood is lowered and this is called pathological condition hypoproteinemia.

Diagnostics and norms of the indicator

An indication for the determination of blood protein is the diagnosis of:

pathologies and
recurrent chronic infections
burns and malignant neoplasms
various specific pathologies
diseases of the gastrointestinal tract
eating disorders and various degrees exhaustion
and violations of metabolic processes

In addition, the detection of total protein and its concentration is carried out as the 1st stage of preparation for comprehensive examination health status. Such a study may be prescribed in order to assess the reserves of the body before the operation, various medical procedures and before taking medication.

In addition, an indication for the determination of the total protein is the need to assess the effectiveness of the therapy and the prognosis of the current pathology.

Total protein norms:

In newborns normal protein in the blood is considered 45-70g / l.
Over the next 15 years, this figure rises to a level of 60-80 g/l.
In adult patients under 60 years of age, the norm of such a compound in the blood reaches 65-85 g / l.
After 60 years, the rate of such organic matter decreases to a mark of 62-81 g / l.

In some cases, a person may experience slight downward deviations from the norm, and this may occur under the influence of the following factors:

severe dehydration
period of breastfeeding
pregnancy
insufficient intake of protein from food
taking certain types of medications
strong physical exertion on the body

You can determine the level of protein in the human body with the help of, which is carried out in the morning and always on an empty stomach. Last reception food before the study should be no later than 8-12 hours. On the day of the analysis, it is recommended not to eat too much protein food, not to drink a lot of fluids and to give up heavy physical activity on the body. The fact is that all these factors can affect the final result of the study in one direction or another.

Causes of a decrease in protein in the blood

AT medical practice such a pathology as a decrease in the level of protein in the blood is called hypoproteinemia.

Its presence can signal some diseases and disorders occurring in the human body:

hepatocellular insufficiency, which developed against the background of acute and chronic pathologies liver
improper and irrational nutrition in the absence of any pathologies affecting the internal organs
depletion of the human body, which is caused by long-term diseases and infectious-purulent inflammations
various pathologies of pregnancy, for example, preeclampsia
organ diseases endocrine system, that is, a decrease in the work of the thyroid gland and hyperfunction
them various immunodeficiencies
disruption of work with its enzymatic deficiency
with various complications
severe form of anemia, malignant neoplasms and bleeding;
accelerated excretion of protein from the body with urine serious illnesses kidney and
pathologies of the stomach and intestines in chronic form, which are accompanied by a violation of the process of digestion and absorption of protein components from food

A symptomatic decrease in the level of total protein in the human body can be expressed in the formation of tissue edema. Typically, such a symptom is observed with a significant decrease in total protein, that is, below 50 g / l.

A decrease in the concentration of protein in the blood is always considered dangerous signal, which indicates different pathological changes. The human body, which is in this state, becomes completely defenseless to the effects of various adverse factors and is not able to recover on its own.

How to raise protein in the blood?

In order to answer the question of how to raise the total protein in the blood, it is necessary to identify the cause of the decrease in protein. This can be done after a biochemical blood test and a comparison of all its important indicators. Only the analysis of all components makes it possible to answer the question of what caused such a deviation.

In the event that the reasons for the decrease in protein are not pathological, then it should be carefully raised. The fact is that if the body is not accustomed to the intake of protein foods, then its abrupt introduction can result in indigestion. With a very low protein in the blood, make up special diet must be an experienced proper nutrition. The diet should be as varied as possible, which will avoid severe stress on the digestive system.

Needed by the body for normal operation Proteins are present in both plant and animal foods.

Experts say that animal proteins are absorbed much better and faster due to their composition. Despite this, in the human body, both must act. The fact is that proteins contain amino acids, each of which is simply necessary for the body. It is for this reason that it is necessary to consume foods containing animal and vegetable proteins in sufficient quantities.

A large amount of animal protein is found in the following products:

fish
low fat cottage cheese
meat of beef, veal and poultry
seafood

In addition, it is necessary to consume vegetable protein and its largest amount is found in the following products:

chocolate
peanut
almond
brown rice; bread with bran
wholemeal pasta

More information about the blood test for total protein can be found in the video:

The average amount of protein is present in chicken eggs, milk, cottage cheese and meat. In addition, experts usually recommend eating those foods that contribute to its increase in the blood, that is, vegetables, fruits, mushrooms and berries. Some people need to consume twice as much protein per day, and these categories include:

women during pregnancy
when breastfeeding
people involved in professional sports
people doing heavy physical work

A decrease is considered a dangerous signal and may indicate various pathologies. However, do not panic, but you need to visit a specialist. He will carefully study the indicators of the analysis, determine the presence of diseases and, if necessary, prescribe effective treatment.

Proteins (proteins) are involved in over a hundred biochemical processes in the body. The composition of plasma and blood directly depends on their proper assimilation and metabolism. And with the help of an analysis of the content of total protein in the body, you can determine the course of many diseases, including hidden ones.

According to research, the level of total protein in the blood is greatly influenced by the diet and lifestyle of a person.

From this article you will get answers to the following questions:

What is the norm of protein in the blood of a healthy person?
Does the norm depend on age, gender?
What methods can be used to quickly raise its level? Will a specialized diet, traditional medicine help in this?
What can lower its concentration?

General information

The very peptide compounds that contain protein play a transport function in circulatory system. That is, with their help, micronutrients enter the cells, and waste products are removed from them.

Also, the protein is an integral part of the formed elements, participating in the synthesis process:

With the help of proteins, the release of fats and carbohydrates from the burning is also carried out, respectively, the nominal body temperature is maintained.

The main types of proteins in human plasma:

- is the main plasma protein, plays a key role in maintaining blood pressure osmotic movement of blood through blood vessels. It is also a binder for complex lipid chains and many drugs.
- mainly take on the transport function. It is with their help that vitamins, minerals, protein combinations are distributed throughout the body (from which muscle). Globulins are also involved in the work immune system, carrying out the transport of leukocytes to the foci of the spread of infection.
- a water-soluble protein, ranks third in the quantitative norm in the blood. Upon contact with thrombin, it precipitates, forming the so-called "fibrofilaments" - it is they that form the basis of the fibrin polymer, which literally clogs the damage blood vessels in combination with platelets.

The above are only the main variations of the proteins included in the composition of the blood. But in total there are over 100 varieties, each of which takes on a number of biochemical functions of the body.

The norm of total protein in the blood

According to accepted standards and directives of WHO ( World Organization Health), the following indicators are considered the norm of total protein in the blood (grams per liter):

newborns- from 45 to 70;
children under 3 years old- from 51 to 73;
children under 15- from 60 to 81;
15 years and older- from 65 to 85;
over 65 years old- from 62 to 81.

The indicators are conditional. Much more important for diagnosis are the indicators of individual proteins, as well as their derivatives.

Normal values during pregnancy

Low total protein in the blood during pregnancy can provoke the development of many pathologies in the unborn child and therefore requires drug enhancement. It is the protein that acts as a “building component”, from which organs, tissues, neurons, blood, and so on are formed.

Accordingly, its deficiency will lead to the fact that the fetus will not be able to fully form. This is especially important in the second and third trimester, when the child's body is actively gaining weight.

The level of protein in the blood during pregnancy is significantly reduced. It - normal phenomenon, just indicates that a significant part of it is transported through the placenta to the body of the unborn child.

If for an adult the norm is about 65 - 85 grams of protein per liter of blood, then during pregnancy, this figure drops to 55 - 65 grams per liter. Accordingly, below 55 is considered a deviation from the norm.

How to boost - 3 main methods

Below we look at 3 main ways to influence the level of total protein in blood plasma.

1. Change your diet

What foods increase blood protein levels? The answer is obvious - those in which high content squirrel. These include:

Meat. In beef, on average, up to 30 grams of protein per 100 grams of product. AT chicken fillet- up to 25 grams and so on.
Egg whites. One boiled egg contains about 3 grams of protein.
Cottage cheese. Contains up to 18 grams of protein per 100 grams of product. In fat-free - a little less, about 12 - 14 grams.
Seafood. Fish contains approximately 12-15 grams of protein per 100 grams. More - in caviar.
Legumes. This also includes peas and beans. Contain 20 to 25 grams of protein per 100 grams.
Cereals. Depending on the culture, they contain from 8 to 12 grams of protein per 100 grams of the finished product.
Nuts. Contains up to 30 grams of protein. This also includes peanuts, pistachios, walnuts, pine nuts.

But it is worth considering that protein is normally absorbed only with a sufficient level of vitamins, minerals, and other micronutrients in the blood. The indicator of carbohydrates is also important, since energy is necessary for the normal course of the digestion process. Accordingly, in order to increase the amount of protein that the body absorbs from food, it is necessary to follow a varied and complete diet.

The need for proteins in men is slightly higher. This is due to the more developed muscular system, the basis of which protein compounds are. But the level of protein in the blood in men and women is almost the same.

2. Use proven folk remedies

To increase protein in the blood folk remedies, quite often recommend the following options:

A decoction of corn grains. For cooking, take 5 tablespoons of dry ground seeds, pour 2 liters of water. Bring to a boil, then let simmer for another 20 minutes over low heat. After - insist until the grains become soft. Next - strain, take 100 grams of decoction 2 times a day after meals. The course of treatment - until the prepared decoction is over.
Seaweed. It is consumed in the form of a salad with the addition of vinegar, spices, onions, garlic (cook to taste, there is no clear recipe). There are 2 times a day for lunch and dinner. At one time, it is recommended to eat at least 40 grams of algae.

3. Take vitamin complexes

Universal drugs, the intake of which will help to quickly raise the protein in the blood - does not exist. Only a diet in combination with taking vitamin preparations can contribute to this. The best performers in this regard are:

Alphabet. Combined vitamin complex. Perfect for men, adults and children over 12 years old. It contains iron, which stimulates biochemical processes involving proteins.
Hematogen. Sold in pharmacies in the form of diet bars. It also contains a lot of iron.
Duovit Multivitamin. Suitable for children too.

Again - these funds should be taken only in combination with a protein diet. Otherwise, there will be no improvement.

What lowers it?

The level of protein in the blood decreases rapidly when exposed to the following factors:

Vegetarianism. It means avoiding food of animal origin. But it is in meat, milk, eggs that most of the protein, in vegetable food- many times less.
Lactation. During breastfeeding, protein naturally decreases. This is not a deviation from the norm. But if it falls below 55 grams per liter of blood, then the diet should be adjusted.
Lack of fluid in the body. May occur while taking certain medications, alcohol or during significant physical exertion.
Liver diseases. Most of the proteins that then enter the bloodstream are produced in the liver. Accordingly, diseases this body can negatively affect the synthesis of proteins that form the basis of blood plasma.
Depletion of the body. Most often occurs in the background long-term treatment infectious diseases. This not only reduces the level of protein in the blood, but also reduces the rate of its absorption.
Some diseases of the endocrine system. In particular, diabetes.
Renal failure. Often leads to an increase in protein in the urine.
Diseases of the gastrointestinal tract. They slow down the process of splitting protein compounds, respectively, the body is deficient in amino acids.

Conclusion

Total The best way raising the concentration of protein in the blood is an increase in the amount of protein food consumed. You should first carry out complex diagnostics and eliminate infectious diseases, normalize the functioning of the liver, kidneys, gastrointestinal tract.

It is essential to maintain protein normal level and during pregnancy, since with a deficiency there is a risk of developing pathologies in the unborn child.
