Read more about different types of diabetes (a pre-existing condition), states with the highest rates of diabetes, disparities among demographics, risk factors, and more.
Fast Facts on Diabetes
Diabetes covers a collection of diseases characterized by elevated blood glucose levels. When someone has diabetes, their body can’t produce or use insulin—a hormone used to convert blood glucose to energy—which leaves excess blood glucose in their system.
There are three main types of diabetes:
- Type 1 Diabetes: Insulin-dependent diabetes usually develops in children and adolescents but can happen in any age group. It can be treated successfully by managing blood sugar, regular checkups, and following a healthcare professional-recommended lifestyle.
- Type 2 Diabetes: Type 2 diabetes most often develops in people over age 45, but more and more children and adolescents are also developing it. It can be treated and prevented by managing blood sugar, making healthier lifestyle changes, and maintaining good physical activity.
- Gestational Diabetes: Gestational diabetes develops during pregnancy in people who don’t have diabetes. Gestational diabetes can be managed by following your doctor’s treatment plan.
What are the symptoms of diabetes?
Type 1 diabetes symptoms can start within weeks, while type 2 diabetes symptoms develop over the years. Symptoms of diabetes include but aren’t limited to:
- Unexplained weight loss
- Increased hunger, thirst, and urination
- Blurred vision and fatigue
- Numbness or tingling in the hands or feet
People with type 2 diabetes often show no symptoms until they experience diabetes-related health outcomes, such as high blood pressure, blurred vision, or cardiovascular disease.
Diabetes risk factors
Risk factors for type 1 diabetes aren’t as straightforward as prediabetes and type 2 diabetes, but family history and age can usually indicate a high risk. In the United States, non-Hispanic white people are more likely to develop type 1 diabetes than Black and Latino people.
Risk factors for type 2 diabetes, prediabetes, and gestational diabetes include obesity, physical inactivity, family history, and more. Certain ethnic groups such as Black, Latinx, American Indian, and Alaska Native people are also at a higher risk, along with Pacific Islander and Asian American groups.
The effects of diabetes
When improperly managed, diabetes is a significant cause of blindness, kidney disease and failure, heart disease and heart attacks, lower limb amputation, stroke, and more. Diabetic people are also at an increased risk of experiencing complications from other health issues, including COVID-19.
How common is diabetes in the United States?
According to the National Diabetes Statistics Report, diabetes affects 37.3 million people in the US, with 28.7 million diagnosed diabetes cases and 8.5 million undiagnosed cases. About 96 million people are reported to have prediabetes: a serious health condition involving a higher-than-normal blood sugar level.
