If your body doesn't make enough insulin or the insulin doesn't work right, the sugar cannot get into the cells. It stays in the blood. This makes your blood sugar level high, causing you to have diabetes. As a result, glucose builds up in the blood, overflows into the urine, and passes out of the body. Thus, the body loses its main source of fuel even though the blood contains large amounts of glucose.
People can get diabetes at any age.
Most people get diabetes when they are over 40 or 50 years old. People with type 2 diabetes follow a special diet and may take diabetes pills. However, sometimes they need insulin shots. Some people get diabetes as children or teenagers. This means they need daily insulin shots.
