Protein in the urine of a pregnant woman.
• Normally, there is no protein in the urine, but during pregnancy a slight increase to 0.033 g / l is allowed, which is caused by strong emotional feelings for the health of the fetus, possible overheating in the summer or hypothermia in the cold season, the intake of undenatured protein foods (raw eggs and home-made unboiled milk), the presence of allergies at the time of the test, and indeed, a strong burden on the kidneys.
• Toward the end of the second trimester, a small amount of protein may appear due to mechanical compression of the kidneys by a pregnant growing uterus, but this phenomenon is not permanent, and is not dangerous only if there are no other signs of kidney disease.
• Also, the protein can get into the urine along with vaginal discharge, therefore, in order for the result of the analysis to be as accurate as possible, it is necessary to follow all the rules for sampling urine.
The appearance of protein (proteinuria) indicates diseases of the kidneys (pyelonephritis, glomerulonephritis, nephropathy of pregnant women, etc.), urinary tract (cystitis, ureteritis) or preeclampsia (late toxicosis).
