Wounds of diabetic patients usually take 2-4 weeks to heal, of course, the specific time should also depend on the diabetic patient’s blood sugar control level, nutritional status, wound size, the presence of infection, and the presence of vascular complications resulting in insufficient blood supply to the wound site and other circumstances. If the diabetic patient’s blood sugar control is relatively good, the nutritional status of the whole body is also relatively good and the wound is not very large, there is no infection, the local blood supply is not impaired, may be in about 2 weeks can be completely healed. On the contrary, if the diabetic patient’s blood sugar is high and the nutritional status is poor, the wound area is large, and there is local infection, the wound healing time will be longer, and it will take at least 1 month to heal.
