The use of a lap band is recommended for women who have had a cesarean section after delivery, while most women do not need to use one after a normal delivery. For women who have had a caesarean section, the purpose of using a lap band is primarily to immobilize the wound. When getting out of bed, the belt can tighten the skin and abdominal tissues around the wound to avoid pulling on the wound when moving around, which may cause pain or even split the incision. For women who have a normal delivery, most of them do not need to use a belly band after delivery because there is no incision on the abdomen, so there is no need to use a belly band to fix the wound. It is recommended that the use of a lap-band after delivery should be strictly in accordance with medical advice. Avoid using it for too long or pulling it too tightly, which may affect the healing of the wound.
