Diabetes Type 1
Also called: Insulin-dependent diabetes, Juvenile diabetes, Type I diabetes
Diabetes means your blood glucose , also called blood sugar, is too high. With type 1 diabetes, your body makes little or no insulin. Insulin is a hormone from your pancreas that helps glucose move from your body into your cells, where it is used for energy. Your body can make glucose, but it also comes from the food you eat. Without insulin, too much glucose stays in your blood. Over time, high blood glucose can lead to serious problems with your heart , eyes , kidneys , nerves , gums, and teeth. If your blood glucose gets very high, you can develop diabetic ketoacidosis (DKA). It happens when your body doesn't have enough insulin to allow glucose into your cells. Instead, your liver breaks down fat for energy, which produces ketones. When ketones build up too quickly, they can reach dangerous levels. DKA is a life-threatening emergency.
