Generally, the cesarean section wound will heal after one week. Because within three days after cesarean section is the period of tissue decomposition, by the fourth day tissue cells proliferate, elastic fibers and collagen fibers increase, the wound begins to heal, and by about a week after the cesarean section, the wound basically heals well. However, the wounds in the abdominal cavity, especially the uterine incision, can heal only after 42 days after delivery, and the scar of the uterine incision can recover some elasticity only two years after the operation. Therefore, it is best to wait two years after cesarean section before you can get pregnant again to avoid any adverse effects on your body. Before the wound heals, women who had a cesarean section must reduce abdominal forceful movements, such as forceful defecation, forceful coughing, lifting heavy objects, squatting, holding children, etc., which are not conducive to wound healing. It is best to rest in a side-lying, slightly flexed position to reduce abdominal wall tension. At the same time, keeping the wound clean and dry can effectively prevent infection and promote wound healing. Immediately after removal of the stitches, a dressing such as silicone elastic bandage or elastic mesh sleeve can be applied under the guidance of the doctor to prevent scarring effectively. Once the wound shows local redness, swelling, heat, cracking, etc., or purulent discharge, etc., be sure to go to the hospital for examination and treatment as soon as possible. In addition to the above care, you can eat more vitamin-rich foods such as fruits, eggs and lean meat after delivery, which can promote blood circulation and improve epidermal metabolic function, which is beneficial to wound repair and prevent scar itching.
