In addition to carbohydrates, other body processes also raise blood sugar levels.When a person fasts, which is defined medically as not eating or drinking anything aside from water for at least eight hours, the release of glucagon is triggered in the body.
In sum, when diabetes is not present the body responds to all blood sugars by manufacturing insulin in proportion with the glucose level.

When it comes to fasting blood sugars, insulin lowers and stabilizes the levels so that they remain in a normal, healthy range.
A lower than normal result may point to hypoglycemia that is caused by a specific type of tumor in the pancreas, and further diagnostic testing is needed.
