Anyone who has come into contact with diabetes knows that diabetics, because of their long-term high sugar status, have poor blood circulation in their bodies and have difficulty healing once they are injured, so diabetics are usually careful to try not to get hurt, and are even more cautious about having surgery, so when they know that bariatric metabolic surgery can treat diabetes, many people are concerned in this regard. The problem of difficult wound healing in diabetic patients has actually always been reflected in weight loss metabolic surgery. Before laparoscopic technology became popular, bariatric surgery was performed through an open abdomen, leaving a long wound in the abdomen that was difficult to care for, so the complication rate was much higher then than now. With the popularization of laparoscopic technology, this surgery now requires only 3 to 4 small 0.5-1cm openings in the patient’s abdomen, and with professional care, healing will be fast, generally healing in a few days, almost no wound infection. Diabetic wounds are difficult to heal mainly because of high blood sugar, if the blood sugar is controlled at a normal level, then the wound healing will not be much more difficult than for ordinary people. The weight loss metabolic surgery itself has a very good blood sugar lowering function, and there are even many patients whose blood sugar has returned to normal levels after the surgery, directly stop taking hypoglycemic drugs. So as long as the weight loss surgery is done in a regular medical institution, there is no need to worry too much about the wound healing, the medical staff can basically handle it very well.
