Doctors don't know what causes Paget's disease of the breast. The most widely accepted theory is that the disease results from an underlying ductal breast cancer. The cancer cells from the original tumor then travel through milk ducts to the nipple and its surrounding skin.
Glucose in the bloodstream provides the primary fuel for all body tissues. Blood glucose levels are highest during the digestive period after a meal. Your blood sugar is lowest when the stomach and intestines are empty. Under normal circumstances, the body tightly controls the amount of insulin in your blood. An organ called the pancreas, which is tucked behind the stomach releases the hormones insulin and glucagon to regulate blood sugar levels.
Blood glucose levels are closely regulated and maintained within a narrow range. Learn how the pancreatic hormones, insulin and glucagon, maintain normal blood sugar levels and how other nutrients can be converted to blood glucose in this lesson.lucose is a simple sugar that is used as energy by your body and brain. Your body works hard to regulate the amount of sugar in your bloodstream and maintain the normal blood glucose range between 70 mg/dl and 110 mg/dl. Much of this regulation is done by hormones secreted by your pancreas.
