Protein in urine. Causes of appearance

The protein in the urine in medicine is calledproteinuria. 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 theurinary bladder, ureters and renal pelvis. In women, proteinuria occurs 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 whyreveals a protein in the urine, is considered 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,accompanying urological diseases. The appearance of protein in the urine on the background of infectious pathologies is accompanied by a fever, pain in the lumbar region. Against the background of inflammatory processes, proteinuria is accompanied by chills, fever. Frequent severe pain in the back. Later 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 passappropriate analysis. It is important to pay attention to the molecular mass. According to this indicator, the kidney function is determined on the background of proteinuria. When a prevalent 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 perliter. 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 only by availabilityproteinuria diagnosis can not be made. For example, the inflammation is indicated by leukocytes 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 laterthirty-second week, indicates a nephropathy (a disorder of the placenta, provoking premature birth). 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 numbers is notrequires 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 of a childa salt-free diet is prescribed (an exception to 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 for several months.

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