More than 34 million Americans have diabetes, meaning their bodies either do not produce insulin or can’t use it properly. (Insulin is a hormone that helps the cells in our bodies absorb the glucose [sugar] in our blood, which we use for energy.)

Over time, uncontrolled diabetes can lead to a host of serious health issues, so if you have diabetes, it’s important to understand the condition and how to properly manage it.

Our goal for this page is to provide a resource where you can get answers to your diabetes-related questions and connect to other information related to diabetes.
