How long it takes for a cesarean incision to heal is related to the woman’s physical condition and subcutaneous fat content, and needs to be analyzed on a case-by-case basis. In general, the skin incision can be healed within 5-7 days after the operation, but the healing time of the fat layer and muscle below the skin varies from person to person, and it takes about 4-8 weeks to heal completely. If the maternal subcutaneous fat is thicker, the incision after cesarean section is prone to fat liquefaction, which shows that the epidermal layer of the skin heals well, but the incision will tear with a little force, so that fat or oily secretions flow from the incision, and the healing time in this case will be relatively longer. If there is redness, swelling, oozing and hard knots, you should go to the obstetrics department for cleaning and disinfection. In addition, the mother should eat more protein-rich food, such as lean meat and fish, to facilitate the healing of the incision.
