It is a disease that happens when your blood sugar is too high.
As blood sugar is our main source of energy and comes from the food we eat.
Insulin, a hormone made by the pancreas, helps sugar from food get into our body to be used for energy.
Sometimes your body doesn’t make enough—or any—insulin.
And that's when sugar stays in our blood.
Over time, having too much sugar in our blood can cause health problems.
