What is Diabetes?

US News & World Report Best Hopitals Badge for 2025-2026 for Diabetes and Endocrinology

Your body needs to convert the food you eat into energy. Diabetes is a chronic disease that affects this process. Most of the food we eat is broken down into glucose (sugar) and released into the bloodstream for the body to use as energy. When you have diabetes, your pancreas doesn’t release enough insulin, or the insulin is not used efficiently, which allows too much blood sugar to stay in your bloodstream. This could eventually cause serious health problems such as heart disease, vision loss and kidney disease.

37.3 Million US Adults have diabetes

Types of Diabetes

Infographic showing the distribution of diabetes types. A donut chart illustrates that 5–10% of cases are Type 1 diabetes, caused by an autoimmune reaction that stops the body from producing insulin. The remaining 90–95% are Type 2 diabetes, where the body does not use insulin efficiently and cannot maintain normal blood sugar levels.

Prediabetes

Infographic stating that prediabetes is when blood sugar levels are higher than normal, raising your risk for type 2 diabetes, heart disease, and stroke. A bold statistic reads “96 MILLION” followed by “More than 1 in 3 US adults has prediabetes.”
