Protein in the urine: what does it mean? The reasons for the increase and the rate

Urinalysis is a traditional study, prescribed even for healthy women, for example, during pregnancy. Sometimes the doctor, seeing protein in the analysis, says it is not scary.

Is it true and at what level of protein in the urine should be alarmed? All doubts disappear if the woman herself knows the limits of the increase of proteins in the urine and its possible causes.

Protein in urine

Protein in urine

urine protein in women

The ideal urinalysis is a complete lack of protein. However, the figure “often” contains the figure 0.033 g / l. This indicator is called traces of protein, it is also the boundary between normal and deviation.

The appearance of traces of protein in the analysis of urine is often caused by physiological reasons (malnutrition, poor hygiene before taking urine for analysis, etc.). In such cases, a reanalysis is usually assigned.

Elevated protein in the urine is indicated by the medical term "proteinuria". At the same time indicators of the general analysis of urine is not enough, it is important to consider the amount of protein lost in the urine per day. Normal daily level - no more than 150 mg / day.

The pathological condition of proteinuria is divided into several stages depending on the daily protein loss in the urine:

  • easy - loss of protein less than 1 g / day;
  • moderate - an indicator of proteinuria 1-3 g / day;
  • severe - output of proteins in the urine of more than 3 g / day.

Causes of an increase in urine protein

Factors provoking proteinuria can be quite harmless, but even persistent fixation of traces of protein suggests some impairments associated with kidney function.

The physiological causes of increased protein in the urine in women are more likely to provoke the appearance of its traces in the analysis. Protein at the level of 0.033 g / l provoke:

  • severe physical exertion;
  • nutritional errors;
  • hypothermia;
  • stress;
  • long sunbathing, tanning;
  • lack of hygiene in the collection of analysis, menstruation in women;
  • late pregnancy;
  • the specifics of standing work, provoking stagnation (for example, the seller);
  • physiotherapy (especially douche);
  • active palpation of the kidneys at the doctor.

Usually, the urine protein index is normalized after the provoking factor is eliminated.

However, physiological effects, prolonged in time, can lead to the development of a pathological condition and a significant loss of proteins in the urine.

Diseases for which there is a protein in the urine:

  • pathology of the urinary system - pyelonephritis, glomerulonephritis, cystitis, prostatitis, kidney injuries, kidney and kidney stones, kidney tuberculosis;
  • infectious diseases accompanied by high fever - severe influenza, pneumonia;
  • severe allergic reactions;
  • hypertension;
  • diabetes, obesity;
  • toxin poisoning;
  • appendicitis (proteinuria combined with high blood leukocytosis);
  • the negative effects of certain medications (for example, oncology treatment with cytostatics);
  • systemic pathology - lupus erythematosus;
  • malignant tumors - leukemia, myeloma, neoplasms in the bladder and kidneys.

Products that increase protein in the urine

To find out the true cause of proteinuria and the purpose of treatment, you should exclude a false urine test result. Along with compliance with hygienic rules during the collection of urine, you should pay attention to food for 2-3 days before the test.

Some foods trigger abnormal protein in the urine. These include:

  • salty food (eating herring often provokes protein in the urine during pregnancy);
  • overlay on sweets;
  • spicy foods, irritating the kidneys;
  • pickles containing vinegar;
  • abundant consumption of protein foods - meat, fish, eggs, raw milk;
  • alcohol, including beer;
  • mineral water in large quantities.

Insufficient fluid intake also leads to proteinuria, and excessive intake of vit. C. Even long-term use of dogrose infusion, rich in ascorbic acid, irritates the kidney parenchyma and can provoke an exacerbation of kidney disease and changes in urine analysis.

Aspirin, cephalosporin, oxacillin, polymyxin, streptomycin and medicines containing lithium also have an irritating effect on the kidneys. Before diagnosis, their reception is usually canceled.

Symptoms of pathological conditions

Symptoms of increased protein A small amount of protein in the urine usually does not give external signs. Only prolonged or severe proteinuria affects the patient's condition. Women may celebrate:

  • swelling - a sign of loss of blood protein;
  • increased a / d - signals of developing nephropathy;
  • weakness, lack of appetite;
  • muscle pain, recurring cramps;
  • temperature rise.

You can visually note the following changes in urine:

  • the appearance of foam with shaking - accurately indicates the presence of protein;
  • muddy color, white sediment - elevated protein and leukocytes in the urine;
  • brownish color - a sign of the presence of red blood cells in the urine;
  • a strong ammonia smell - causes suspicion of diabetes.

In case of severe damage to the renal tissue, developing stone formation, there is protein in the urine, leukocytes and erythrocytes.

Increased protein in the urine during pregnancy

If the kidneys cope with an increase in the load during pregnancy, the urine will respond by not having protein in it. However, even its presence in the general analysis still does not indicate pathology.

Even an increase in the daily protein in the urine to 300 mg is considered physiological and does not cause pathological abnormalities in the mother and fetus.

The rate of protein in the urine in late pregnancy is even higher - up to 500 mg / day. However, these indicators should not be alarmed if the pregnant woman has no associated symptoms.

Toxicosis, edema, increased pressure in combination with proteinuria are alarming signals that require a more thorough examination of the woman.

Treatment

Treatment of increased protein in urine analysis In physiological proteinuria, drug treatment is not carried out. In this case, the correction of nutrition, the abandonment of alcohol, full rest and sleep.

Large indicators of protein in the urine require more thorough diagnosis to identify the cause of the deviation and often hospitalization. Depending on the identified disease are assigned:

  • antibiotics;
  • antihypertensives;
  • corticosteroids;
  • detoxification infusions - Hemodez well purifies the blood of toxins during intoxication, especially pronounced in renal diseases;
  • hemosorption, plasma exchange.

An integral part of the treatment is a diet with salt restriction to 2 g / day with the exception of pepper, smoked meat, strong tea / coffee. It is imperative to limit fluid intake, especially with concomitant proteinuria and edema and high pressure.

What is dangerous in urine protein?

Before determining the danger of protein in the urine of women, it should be understood what it means for the body.

Protein in the urine - an indicator of impaired filtration ability of the renal membranes. Together with large protein molecules, red blood cells can be flushed out of the blood, which leads to anemia and aggravation of the patient's condition.

Proteins are the building blocks of all cells in the body. When it is lost, the processes of formation of new cells are disrupted. An increased urine protein index leads to a slower regeneration of the tissues of organs and systems, thereby delaying the healing process.

Proteinuria during pregnancy is fraught with oxygen starvation of the fetus and its underdevelopment. In severe cases, this condition threatens with the development of preeclampsia, which provokes premature labor and increases the risk of fetal death in the fetus by 5 times.
