Whether proteinuria in pregnant women will have an impact on the fetus is judged according to the disease, such as the following: First, some pregnant women may experience increased kidney burden during pregnancy, resulting in protein loss will cause proteinuria, which is a normal physiological reaction and basically will not have a great impact on the fetus, so there is no need to worry. Secondly, pregnant women who suffer from gestational hypertension during pregnancy may also develop proteinuria, which has a certain impact on both the pregnant woman and the fetus, and may lead to various problems such as fetal growth restriction and neurological damage. It may also cause symptoms such as low amniotic fluid and fetal distress, and in abnormal cases, fetal death or premature birth. Thirdly, proteinuria may also occur when suffering from nephritis or other diseases, and the impact on the fetus should be judged according to the severity.
