Diabetes Mellitus is a condition where the amount of glucose in the blood is too high because the body cannot use it properly. Glucose comes from the digestion of carbohydrate containing food and drinks, and is also produced by the liver. Carbohydrate comes from many different sources including starchy foods such as bread, potatoes and chapattis, fruit, sugar and other sweet foods. Turning the sugar into energy for our muscles requires the hormone Insulin, which is produced by the pancreas. Insulin is vital for life. It helps the glucose to enter the cells where it is used as fuel for energy so we can work, play and generally live our lives.
