The norm of protein in the urine in men and the reasons for its increase
In the kidneys there is a constant filtration of blood and unnecessary, spent part of it in a small amount is excreted from the body with urine. In this case, normally, the renal membrane does not miss the protein molecule because of its magnitude, most of them remain in the blood. Insignificant amounts of protein can still penetrate through the kidneys.

Why does the protein in the urine?
appearance of small amounts of protein in the urine sample can contribute some so-called physiological reasons, for which the appearance of protein in the urine is not dangerous. First of all, this:
- Adolescence, when changes in the body, leading to a minor proteinuria occur against a background of intense growth. It is not dangerous and usually completely passes with the completion of the puberty period.
-
Often the protein rises in athletes, especially on the background of intensive training, or during the competition. In general, any very strong physical activity can cause a short-term appearance of protein in the urine. If you remove the load and restore the normal life of the body, the analysis comes back to normal after 2-3 days.
- a lot of stress, psycho-emotional overload, significant hypothermia - all this can also cause short-lived proteinuria.
- The prevalence of meat( especially fatty) in the diet may affect the overall analysis of urine by the appearance of a small amount of protein. To the same can lead and abuse of sports nutrition( protein-carbohydrate mixtures, geyners, etc.).See: "Is meat for men more good or bad?".
Pathological proteinuria
A persistent and / or significant increase in protein in the body of a man is always the cause of any disease. Pathology can develop:
- in the kidney itself( renal proteinuria);
- outside the kidney, without touching the organs of the urinary system( prerenal and postrenal proteinuria).
Renal proteinuria
If the cause of protein in the urine in men is kidney pathology, it is, as a rule, heavy inflammation affecting the glomerular apparatus( glomeruli and tubules) and renal membrane. In the first place in the frequency of glomerulonephritis, which, due to inflammation, changes the elasticity of the renal membrane and enhances its permeability. Also, the protein in the urine can appear with pyelonephritis, various kidney tumors( polycystosis, cancer).
Postural Proteinuria
A number of diseases of the urinary system, in which inflammation develops in the urethra( urethra), bladder, prostate gland, can give a picture of the protein in the assay. This is due to the ingestion of products of active inflammation into the urine and is called "false proteinuria."If a man's history includes diagnoses such as acute or chronic urethritis, cystitis, prostatitis, one must always be careful to correctly interpret a general urinalysis.
prerenal proteinuria
reason for the appearance of protein in the urine of men may be different pathologies in organs and body systems. The most likely:
-
diabetes;
- lesions of the cardiovascular system( myocardial infarction, hypertension);
- various body poisoning( acute and chronic);
- acute infectious inflammation( influenza, pneumonia);
- malignant tumors( cancer, leukemia, myeloma);
- stroke, epilepsy.
The mechanisms of the occurrence of proteinuria in these diseases are different and the numerical values of the protein can vary greatly.
Clinical manifestations and diagnosis
With kidney pathology, patients complain of pain in the lumbar region, increased body temperature, impaired urination. The most important in the correct diagnosis is the interpretation of laboratory and functional research methods. Pay attention to the indices of creatinine, urea, residual nitrogen in biochemical blood analysis. Estimate the level of electrolytes and the total protein. Structural changes in the kidney itself can be determined using ultrasound diagnostics.
With inflammatory diseases in the genitourinary area that do not affect the kidneys, it is very important to collect urine correctly for analysis in order to avoid getting mucus and pus from the sites of inflammation. The collected urine is divided into three portions. First, the man urinates in the toilet, when he feels that about a third of the expected portion of urine is allocated, stops urinating and the next part gently collects into a jar for analysis. The last remaining urine is also sent to the toilet. In the first and last portions, there is a high probability of "catching" elements that are not related to the kidneys.
To be sure that the cause of proteinuria lies outside the kidneys, it is necessary to correctly diagnose the underlying disease. Often the pathologies that caused proteinuria are obvious( stroke, myocardial infarction) and are diagnosed due to an obvious clinical picture( acute onset, characteristic course).A number of diseases can occur secretly( diabetes, starting cancer) and require a complete examination of the patient with the advice of appropriate specialists.
Treatment and prognosis of
In order for the male protein to stop appearing in the general urine analysis, it is necessary to cure the underlying disease that is the cause of proteinuria.
- With active inflammation in the kidney apply antibacterial, anti-inflammatory drugs, funds that improve kidney blood flow;
- With extraoral pathologies, it is important to remove the main factors of proteinuria;
- When poisoning - cope with the intoxication of the body;
- With hypertension - normalize blood pressure;
- With diabetes mellitus - to normalize blood glucose level, etc.
The prognosis after the appearance of a protein in the urine in men depends largely on the timely diagnosis and proper treatment of the underlying disease. The patient should remember that any, even insignificant, manifestation of proteinuria requires treatment in a medical institution for a thorough examination.
