The pancreas continues to release a small amount of basal insulin overnight, while a person is sleeping. The nurse knows that if the body needs more sugar: Glycogenesis will be decreased by the liver. The pancreatic hormone glucagon will stimulate the liver to release stored glucose. Insulin will be released to facilitate the transport of sugar. The process of gluconeogenesis will be inhibited.

"Diabetes can affect sensation in your feet and you can hurt yourself without realizing it."
