Diabetes
Diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high. Over time, having too much glucose in your blood can cause health problems, such as heart disease, nerve damage, eye problems, and kidney disease. You can take steps to prevent diabetes or manage it.
An estimated 30.3 million people in the United States, or 9.4 percent of the population, have diabetes. About one in four people with diabetes don’t know they have the disease. An estimated 84.1 million Americans aged 18 years or older have prediabetes.
Many areas of the body can be affected by diabetes. Learn about diabetes health problems.
