Diabetes is a disease that occurs when a person’s body doesn’t make enough of the hormone insulin or can’t use insulin properly. There are 2 types of diabetes. Type 1 diabetes occurs when your body’s pancreas doesn’t produce any insulin. Type 2 diabetes occurs when the pancreas either doesn’t produce enough insulin or your body’s cells ignore the insulin. Between 90% and 95% of people who are diagnosed with diabetes have type 2 diabetes.
When you digest food, your body changes most of the food you eat into glucose (a form of sugar). Insulin allows this glucose to enter all the cells of your body and be used as energy. When you have diabetes, your body doesn’t make enough insulin or can’t use it properly, so the glucose builds up in your blood instead of moving into the cells. Too much glucose in the blood can lead to serious health problems.
