If a woman has edema in the second trimester of pregnancy, there is no increase in protein in the urine, no increase in foam in the urine in general, increase in blood pressure, abnormal protein in the blood, or abnormal blood lipids. It may occur due to changes in the level of estrogen or progesterone in the body and does not require special treatment, only rest and diet. After the end of pregnancy, that is, after delivery, the edema will disappear naturally. If a woman develops edema in late pregnancy, accompanied by an increase in blood pressure, an increase in protein in the urine, an increase in foam in the urine, and possible abnormalities in protein and lipids in the blood, it may be a case of gestational hypertension syndrome, which needs to be actively observed closely and treated accordingly in the obstetrics department. You should not use diuretics when you find edema alone, because in some cases edema is normal and in some cases it is abnormal.
