People with type 1 diabetes pose particular challenges to safely scheduling surgery. People who are dependent on exogenous insulin should generally only fast for 6 hours prior to surgery, and the surgery should be scheduled as early in the morning as possible. This will provide time for food and liquid to clear the stomach and duodenum (reducing aspiration risk), but not so much time as to risk severe hypoglycemia. The provider should provide clear guidance about whether and how to administer insulin the morning of the surgery. In most cases, blood glucose and insulin can be managed immediately prior to and during the procedure.
