What precautions must be taken by a diabetic patient before an operation?

Operations can be done with diabetes, provided some precautions are taken. Blood sugar should be brought down to normal before the surgery. For this reason, insulin injections are given to the diabetic patient during and after the operation. Wounds may take longer to heal than normal patients. Due to the patient’s weak immune system, they may take longer time to come out of the anesthesia. That is why, it is necessary to reveal to the surgeon about the presence of diabetes mellitus before gearing up for a major operation.
