Diabetes mellitus, commonly known as diabetes, is a metabolic disease that causes high blood sugar. The hormone insulin moves sugar from the blood into your cells to be stored or used for energy. With diabetes, your body either doesn’t make enough insulin or can’t effectively use the insulin it does make. Untreated high blood sugar from diabetes can damage your nerves, eyes, kidneys, and other organs.
Diabetes is a condition that leads to high levels of blood glucose (or sugar) in the body. This happens when your body can’t make or use insulin like it’s supposed to. Insulin is a substance that helps your body use the sugar from the food you eat. There are two different types of diabetes: type 1 diabetes and type 2 diabetes. People with either type of diabetes need medications to help keep their blood sugar levels normal.
