Diabetes and Prediabetes Home

Diabetes is a chronic disease in which sugar levels in the bloodstream are above normal. It occurs when a person cannot produce (type 1) or properly use (type 2) insulin. Insulin is a hormone that moves sugar out of the bloodstream into the cells to be used for energy. Prediabetes is a condition in which blood sugar is high, but not high enough to be type 2 diabetes.
