Protein in urine. Causes of appearance

The protein in the urine in medicine is called proteinuria. Typically, this phenomenon occurs during a strong physical strain, after a severe fever, hypothermia, against stress, as well as when consuming protein foods in large quantities. In such situations, proteinuria persists for a short time - for the time of the influence of the external factor.

Protein in urine can appear with inflammation in the bladder, ureters and renal pelvis. In women, proteinuria is detected when menstrual blood is ingested. Protein in the urine of men can appear from the prostate gland. These cases in medical practice are called false proteinuria.

The most common reason for detecting a protein in the urine is a violation of the filtration process in the kidneys. This condition is typical for many pathologies (nephroses, glomerulonephritis, tuberculosis of the kidneys, pyelonephritis, hypertension, systemic lesions of small vessels and tissues). The protein in the urine is also detected during pregnancy (late toxicosis).

By itself, proteinuria is considered a symptom that accompanies urological diseases. The appearance of protein in the urine on the background of infectious pathologies is accompanied by fever, pain in the lumbar region. Against the background of inflammatory processes proteinuria is accompanied by chills, fever. Strong pains in the back are frequent. Late toxicosis and the detection of proteinuria in pregnant women are accompanied by edema, elevated blood pressure.

To determine the protein in the urine, it is necessary to pass an appropriate analysis. It is important to pay attention to the molecular weight. According to this indicator, the kidney function is determined on the background of proteinuria. If a predominant concentration of albumins with a molecular low mass is found in the urine, the protein indicates a minor lesion in the kidney tissue. With increased molecular weight of albumins, proteinuria indicates the development of severe diseases.

A normal reading is 0.002 grams per liter. False proteinuria is characterized by a protein concentration of not more than 1%. The index of 0.025-0.1 grams in the daily volume of urine is considered the norm. When taking the morning analysis, the concentration is not more than 0.033 grams per liter is also a variant of the norm.

It should be noted that it is impossible to diagnose the presence of proteinuria only. For example, the inflammation is indicated by white blood cells and protein, red blood cells and protein indicate damage to any part of the urinary system against the backdrop of stone movement.

In pregnancy, proteinuria, detected after the thirty-second week, indicates nephropathy (a disorder of the placenta that provokes premature births). This pathology is characterized by a fairly rapid development. At the same time, protein excretion in the urine exceeds 300 grams per day.

Elimination of proteinuria occurs when the underlying disease that caused this condition is eliminated.

Protein in urine in children in small amounts does not require treatment. In some cases, the doctor may appoint a reanalysis after a while. If proteinuria is detected in this case, additional studies of kidney function may be required.

Sometimes, to lower the protein in the urine, the child is assigned a salt-free diet (exclusion from the diet of salt). In special cases, the doctor may prescribe special medications. As a rule, the initial doses are prescribed large, after which they decrease. Such funds are recommended for admission within a few months.

It should be noted that the proteinuria in the child, regardless of the cause of it caused, as a rule, to eliminate is simple enough.
