Postpartum swelling will disappear in about 1 week. In late pregnancy, the increased secretion of estrogen in the body and the enlarged uterus will cause obstruction of body reflux, which will easily cause body swelling. The swelling will disappear slowly with sweating and urinary excretion as the hormone level in the body returns to normal 3-5 days after delivery. During pregnancy, swelling can also be caused by gestational hypertension, and it will disappear after normalization of hypertension after delivery. If there are no other complications after delivery, the swelling will disappear in about 1 week. If there are kidney diseases, hypertension and other diseases that will affect the disappearance of swelling, you need to go to the hospital for medical examination in time, and it is best to take reasonable antihypertensive drugs, and it is also recommended to check the kidney function regularly. If the swelling is serious, you can take appropriate diuretic drugs, such as furosemide, which can promote the disappearance of swelling.
