“How can I prepare my body for a surgery with diabetes?”

Exercise and stay hydrated.

Keep track of your numbers everyday and keep track of your blood pressure. You need to write down your numbers so you can tell your doctor. The numbers you give him will tell let him know if it is safe to operate. If you have problems at all, let your doctors know what to do.
I wish you well.

Be sure to take prescribed medications for diabetes. Check your HgbA1c. It is best that is it less than 8.0 in order to optimize healing and prevent infection. If you take injections, you should take half the amount in the morning before surgery. If you take oral medications, you should not take the medication the morning before surgery. It is best to stick to a low carb, high protein diet to maintain low blood sugars with a goal of getting the HbA1c less than 5.5.

Eat a balanced diet, avoid sugars and carbs to minimize elevation of glucose levels. If taking insulin or oral diabetic medications such as metformin, you should be getting instructions from your surgeon or internist involved in your care about when to stop or reduce these medications based on the time of the surgery. Don't shave the body part you will be operated on and ask about using antibacterial soap night before or morning of the surgery depending on time of surgery.
