The wound healing time for peritoneal dialysis varies, usually 1-2 weeks, but is affected by a number of factors, such as significant peritubular exudate, which can affect local healing. Poor nutrition or coexisting diabetes can also affect the healing of the incision. Local infection of the incision can also affect the healing process. Therefore, we need to have a diet rich in vitamins and fiber, such as fruits and green vegetables, and fruits rich in B and C vitamins, such as kiwi, apples, bananas, etc. The intake of high quality protein with low fat and low cholesterol content, such as fish and shrimp, can promote the healing of the wound as soon as possible. If local infection is found during the recovery period, this needs to be treated promptly at the hospital by giving antibiotics or changing the medication to make the wound heal as soon as possible.
