Diabetes mellitus is a chronic disease with disordered metabolism. When we are having carbohydrates (including sugar and starch, etc.), such materials become dextrose after digestion and become glucose as they are absorbed into blood circulation system by the small intestine. The pancreas secretes insulin, helping the glucose to enter into cells for use.
