After cesarean section, if the wound heals well without redness, swelling, hardness, oozing, etc., it does not need to be sterilized for about 10 days, and in individual cases, it needs to be prolonged. If the C-section wound heals well without redness, swelling, hard nodules, oozing, infection, etc., the stitches can usually be removed 6 to 7 days after the operation, and some wounds do not need to be removed. If there is poor wound healing, liquefaction of the incision, infection, etc., it is necessary to extend the time appropriately until the incision heals well. If the mother herself has some underlying diseases, such as diabetes mellitus, etc., it is also easy to make the wound infected and not easy to heal. At this time, prevention should be done, blood sugar control and diet should be paid attention to. After cesarean section, the mother should control the time of sterilization under the guidance of the doctor, and should not decide on her own.
