The pancreas is a gland that is about six inches long and is nestled in the curve of the duodenum. Its cell clusters secrete insulin, which accelerates the burning of sugar in the body. Insulin is secreted into the blood, not the digestive tract. Excessive sugar consumption causes excessive secretion of insulin of the pancreas into the blood stream
. The long term consequences can result in diabetes, hypoglycemia, or hyperglycemia. The larger part of the pancreas manufactures and secretes pancreatic juice, which contains some of the body's most important digestive enzymes, lipases, proteases, and amylases.
