Type 2 diabetes, the most common type of diabetes, is a disease that occurs when your blood glucose, also called blood sugar, is too high. Blood glucose is your main source of energy and comes mainly from the food you eat. Insulin, a hormone made by the pancreas, helps glucose get into your cells to be used for energy. In type 2 diabetes, your body doesn?t make enough insulin or doesn?t use insulin well. Too much glucose then stays in your blood, and not enough reaches your cells.
The good news is that you can take steps to prevent or delay the development of type 2 diabetes.
