What causes high levels of microalbuminuria in pregnant women?

Some current studies have found that there is a very close correlation between urine microalbumin and the process of pregnancy. Urine tests are usually performed in the late pregnancy, and the main test is urine microalbumin. So what causes high urine microalbumin in pregnant women?

Normal urine contains trace amounts of protein and the test result is negative; when the protein content in the urine reaches a certain value, the test result is positive. Urine that tests positive for protein is called proteinuria. This type of urine excreted by pregnant women is called maternal proteinuria. Generally speaking, it is normal for pregnant women to experience this phenomenon. However, if you have kidney disease before pregnancy and the urine protein level is high, it is better to go to the hospital for examination and treatment.

The protein in the urine of normal pregnant women may increase slightly, which is related to increased body position, renal flow and glomerular filtration rate. If the pregnant woman is in good health, her kidneys will undergo some normal changes after pregnancy, such as increase in length and weight. At the same time, the glomerular filtration rate of pregnant women will increase, so the protein filtration will also increase. The 24-hour proteinuria quantity can reach 300-500 mg, and the incidence rate is about 20%. During pregnancy, the spine is lordotic, the liver compresses the inferior vena cava, resulting in increased renal venous pressure, and the enlarged uterus compresses the renal vein, which are the causes of physiological proteinuria during pregnancy. Adopting a lateral lying position often reduces urine protein. Therefore, if a pregnant woman does not have kidney disease during pregnancy, it is normal for her to have proteinuria and there is no need to worry.

Most pregnant women worry that high urine protein will affect the baby's health, which can lead to depression. In fact, the mother's mood has a great impact on the baby, so the editor suggests that if the mother finds that her urine protein is high, she can consult a doctor and do corresponding prenatal examinations. I believe the doctor will give you better advice.
