Glucose, also known as blood sugar, is the body’s main source of fuel. We get most of the glucose from foods and drinks that contain carbohydrates. The foods we eat are broken down and processed by the digestive system and liver and glucose is then released into the bloodstream for the cells to take it in.

Diabetes is a disease that occurs when blood glucose, also called blood sugar, is too high. The glucose circulating in the blood is derived from the foods we eat. Insulin, a hormone made by the pancreas, helps glucose to be transported into cells to be used for energy. Sometimes the body doesn’t make enough insulin or doesn’t use insulin well. Glucose then stays in the blood.
