Diabetes can be operated on for surgery. Many patients undergoing elective surgery are accompanied by elevated blood sugar, so patients with diabetes can undergo surgery when necessary, but they need to have their blood sugar under better control during the perioperative period. Generally, larger surgeries require the use of insulin to control blood glucose throughout the surgery. Insulin control can help the patient’s blood sugar to be more stable and can also help the wound to heal after surgery. However, there are more adverse risks associated with surgery for diabetic patients. But in any case, as long as the patient will have good blood sugar control, it is possible to open the surgery, depending on the patient’s usual blood sugar control situation.
