Diabetes Mellitus as it is known in full, is a common health condition where there is too much glucose in the blood. Glucose is a type of sugar that comes from carbohydrates in the food we eat and is also produced by the liver and is our body’s main source of energy. Most of the food we eat is broken down into glucose. The level of glucose in the blood is regulated by a hormone called insulin. Insulin stimulates cells to absorb enough glucose from the blood for the energy they need. Insulin also stimulates the liver to absorb and store any glucose that’s left over. People who have diabetes either do not produce insulin, produce insufficient insulin or the insulin they do produce does not work properly, so the glucose builds up in your blood instead of moving into the cells. Insulin is made by a gland called the pancreas, which lies just behind the stomach. Insulin allows glucose to move from the blood into the body’s millions of cells and be converted into energy needed for daily life.
