The so-called postpartum repair belt is actually called postpartum abdomen belt. Its main function is to shrink abdominal fat, tighten abdominal muscles and make the body recover faster. Women who give birth naturally, if there is no major bleeding after delivery, can be bound with abdominal straps for more than 6 hours after delivery. For women who terminate pregnancy by caesarean section, because there is obvious incision in the abdomen after delivery, it is recommended to use abdominal belt for more than one week after delivery, and the incision will return to normal.
