Overview of Diabetes in the U.S.
Diabetes is a group of conditions resulting from the body's inability to make insulin, use insulin effectively, or both. Insulin helps to control the body's blood sugar (glucose) levels to ensure sufficient energy. There are different types of diabetes that can affect adults and children of all ages, genders, races, and ethnicities. The types of diabetes include:
- Type 1 diabetes, or insulin-dependent diabetes mellitus, is commonly known as juvenile or childhood diabetes. In type 1 diabetes, the body does not produce insulin.
- Type 2 diabetes can occur in adults or children. In type 2 diabetes, the body does not use insulin properly.
- Gestational diabetes is a type of diabetes that occurs during pregnancy, among pregnant women who have never had diabetes.
- Prediabetes is having blood sugar levels that are higher than normal, but not high enough to be diagnosed as having type 2 diabetes.
People with diabetes must monitor their blood sugar (glucose) level to keep it within a normal, healthy range. People with diabetes should manage blood sugar by checking levels multiple times per day to be sure it is not excessively high (hyperglycemia) or low (hypoglycemia). When diabetes is not well managed or left untreated, it can result in complications such as:
- Kidney disease or failure
- Heart disease
- Nerve damage
- Circulatory problems
- Lower-extremity amputations
The Centers for Disease Control and Prevention (CDC) estimates that 88 million adults in the U.S. have prediabetes, putting them at risk for developing type 2 diabetes and other conditions. Type 2 diabetes accounts for approximately 95% of all cases of diabetes in the United States and is preventable with regular physical activity and healthy weight loss. A person with prediabetes is at an increased risk of developing type 2 diabetes. Lifestyle changes can prevent or delay the onset of type 2 diabetes. Evidence reviewed by the Community Preventive Services Task Force (CPSTF) supports intensive lifestyle interventions for diabetes management and combined diet and physical activity programs for diabetes prevention.
