What is the norm of protein in the urine, and what should I do if I reject this indicator?
The norm of protein in the urine is one of the indicators of human health. It is determined by the biochemical analysis of urine. Finding a small number of proteins in the urine is not a pathological condition, but for different sexes and age groups this number is slightly different.
Indices of the protein in the urine, depending on the age and sex
For men, the limit value of protein in urine is 0.3 g / l. Results exceeding this figure should be alarming.
In childhood, the maximum allowable value is not more than 0.025 g / l.
In boys of adolescence, sometimes the indicators reach 0.7-0.9 g / l. And protein is determined in the daytime, and not in the morning urine. This phenomenon is called orthostatic proteinuria. It occurs against the background of high physical activity and only with the vertical position of the body. This is considered a norm, and it goes with age.
In women, the norm of proteins in the urine is up to 0.1 grams per liter. At pregnancy such figure can reach up to 30 milligrams, but over this condition is considered pathological. However, up to 300 milligrams late in the day doctors are considered as the limit of the physiological norm. Deviations from these figures upwards require additional diagnostic measures, a general assessment of the condition, and in severe cases and placement in a hospital for continuous monitoring.
Physiological Proteinuria
In general, an increase in the concentration of protein bodies in urine can normally be determined by the following factors:
- Physical overload.
- Eating foods high in protein.
- Very long stay of the body in an upright position.
- The last trimester of pregnancy.
- Subcooling.
- Hyperinsolation.
- Active kidney examination with palpation.
- Psychoemotional stress.
- Injuries, concussions of the brain, epipripeds.
There are also a number of pathological conditions in which a high concentration of protein appears in the urine:
- Kidney stasis or renal tubule damage.
- Increased protein production in certain diseases( myeloma).
- Damage to or loss of muscle tissue.
- Inflammation or trauma to the urinary tract.
How does the protein appear in the urine?
The mechanism of appearance in the urine of the protein becomes clear if we consider the principles of kidney function. The main functional unit of these organs is the nephron. Blood, which circulates throughout the body, enters the renal artery inwards, and then, branching into a multitude of small vessels, forms a glomerulus.
Filtering occurs there. From the primary urine, lipids and proteins are absorbed back, and with them a part of the liquid, useful elements, and toxic and ballast substances are discharged outside together with secondary urine, which normally forms up to 2 liters per day.
Now it becomes clear that if the reabsorption conditions are violated, the protein yields in the urine. Sometimes the protein can be detected if it comes from the underlying pathways - the ureters, the bladder, the kidneys, or even the urethra.
Treatment of
Treatment of proteinuria and reduction of the amount of protein in the urine to normal indices is the effect on the etiological factor, as well as the removal of the symptoms of the patient's pathological condition.
To determine the cause of abnormalities, it is necessary to conduct repeated analyzes, compare with complaints and objective methods of research, and only then be determined with the choice of treatment. Self-medication in such situations can lead to quite sad consequences.
Correct interpretation of indicators and help in severe cases can only specialist. Therefore, in the presence of proteinuria, you should immediately consult a doctor for advice and treatment.
With severe protein loss in the urine, the patient needs hospitalization, bed rest, adequate treatment, he must adhere to a diet with the restriction of certain dishes, as well as liquid and salt.
If there are minor abnormalities, the doctor may advise you to undergo a second examination. Physiological proteinuria is not treatable, it passes by itself.
