Darkening of the wound 50 days after cesarean section is usually due to local tissue melanin precipitation, wound scar tissue proliferation, etc., which usually does not affect the patient’s postoperative recovery. However, if it is accompanied by pain, it should be considered as a result of wound infection. In most cases, the wound will begin to heal about 48 hours after the cesarean section, and will be healed in about 7 days. If the mother does not do a good job of protecting the abdominal wound after surgery, often exposed to sunlight, or often eat black beans, black fish, etc., melanin content of the food, resulting in local melanin cell stimulation, precipitation, there will be 50 days after the birth of the wound turned black. At the same time, some women with scarred bodies may experience scar tissue hyperplasia 2-3 weeks after surgery, and the scar tissue is usually darker in color, resulting in darkening of the wound 50 days after cesarean section. The above reasons are common physiological factors, which usually have no effect on the wound and recovery of the mother, and usually do not lead to discomfort, so there is no need to worry too much. However, if a woman finds that her wound has turned black and is accompanied by redness, swelling and pain, it should be considered that this is due to the fact that she has not paid attention to her wound after discharge from the hospital, and there are cases of exposure to water, which leads to the entry of bacteria in the water and air into the wound, causing it to become infected. In addition to the above reasons, there are many other clinical reasons that can cause the wound to turn black 50 days after the cesarean section, and it is recommended that the mother first seek medical examination to clarify the specific reasons.
