How long does it take for the wound of the body to heal after caesarean section?

In recent years, when faced with childbirth, most expectant mothers choose caesarean section. Although it is much less painful than natural delivery, the knife marks left by the operation are very troublesome. Experts suggest that the scab healed after operation should not be removed prematurely. If it is removed too early, it will take away the epidermal cells that are still in the repair stage, and even tear the dermal tissue, which will stimulate the wound to itch. Scar is the trace left on the wound after operation, which is generally white or grayish white, smooth and hard in texture. About two to three weeks after the scar of the surgical incision, the scar began to proliferate. At this time, the local area was red, purple and hard, protruding from the skin surface. There are new nerve endings in the scar, but it's chaotic. The scar hyperplasia period lasts about three months to half a year, and the fibrous tissue hyperplasia gradually stops, and the scar gradually flattens and softens. When the color turns dark brown, the scar will be itchy, especially when I sweat a lot or the weather changes. I often feel itchy until I scratch the scar epidermis and see blood. If it is in summer, people often sweat. Sweat consists of water, salt (sodium chloride, potassium chloride), protein and urea. When sweating, the scar is soaked by sweat, and the salt in the sweat will stimulate the nerve endings inside the scar, thus causing pain and itching. When the weather changes, because the temperature difference between hot and cold and the change of dryness and wetness are much stronger than usual, the holy road endings in scars can sensitively detect this change and tell people with itching and pain as signals. People call it "weather forecast" because of its regularity and sensitivity to weather changes. However, young mothers should not be afraid, the itching of scars will gradually disappear with time. 1. Don't expose the scab of the incision prematurely after operation. Premature exposure of scab skin will take away epidermal cells that are still in the repair stage, and even tear off dermal tissue, which will stimulate the wound to itch. 2. Apply some topical drugs such as triamcinolone acetonide and dexamethasone to relieve itching. 3. Avoid sunlight and prevent ultraviolet rays from stimulating pigmentation. 4. Improve diet, eat more fruits, eggs, lean meat, skins and other foods rich in vitamins C, E and amino acids. These foods can promote blood circulation and improve the metabolism of epidermis. Don't eat spicy food such as pepper, onion and garlic. 5. Ensure the cleanliness of the scar, clean up the sweat discharged from the skin in time, don't scratch it by hand, don't rub clothes or even rinse it with water to stop itching, so as not to make the local area more stimulated and cause further itching.
