Diabetes is a blood disease. People with diabetes have high blood sugar (or glucose) levels. Glucose in the blood comes from foods we eat, and insulin made by the pancreas normally breaks that glucose down. People with diabetes can’t do this, so too much glucose stays in their blood.

More than 34 million people in the United States have diabetes, and one in four of them don’t know they have it. If undiagnosed or unmanaged, diabetes is dangerous.
