Type 2 diabetes, the most common form, is a disease in which the body’s cells don’t use insulin properly. At first, the pancreas makes more insulin to get glucose into the cells, but over time, the pancreas can’t make enough to keep blood glucose levels normal and the result is type 2 diabetes.

Type 2 diabetes increases a person’s risk for several health conditions including high blood pressure, heart disease and stroke. It’s also responsible for as many as 12 percent of deaths in the U.S., three times higher than previous estimates, a January 2017 study in the journal PLOS ONE found.
