Diabetes Facts and Statistics: Essential Insights for 2025
Explore comprehensive diabetes figures, types, risk factors, and health impacts across the United States, with guidance on prevention and management.
Diabetes is a pervasive chronic condition that impacts millions of Americans and has far-reaching effects on health, lifestyle, and the economy. This in-depth guide provides up-to-date statistics, critical facts, and actionable advice about diabetes, prediabetes, and related complications in the United States.
At a Glance: Diabetes in the United States
- About 38 million people—approximately 1 in every 10—have diabetes.
- 1 in 5 people with diabetes are unaware that they have it.
- Diabetes-related healthcare costs and lost earnings amount to an estimated $413 billion annually.
- Prediabetes affects 98 million adults (over 1 in 3), and the majority don’t know they’re at risk.
- Serious complications include blindness, kidney failure, heart disease, stroke, and limb loss.
What is Diabetes?
Diabetes is a metabolic condition that causes high blood glucose (blood sugar) levels. Over time, sustained high blood sugar can damage blood vessels and organs, leading to serious health issues such as heart disease, nerve damage, kidney disease, vision loss, and poor wound healing. There are three main types of diabetes: type 1, type 2, and gestational diabetes.
Types of Diabetes
- Type 1 diabetes: An autoimmune condition where the body attacks insulin-producing cells. It can occur at any age and accounts for about 5–10% of diabetes cases. There is currently no known way to prevent type 1 diabetes.
- Type 2 diabetes: Characterized by insulin resistance and insufficient insulin production, it represents about 90–95% of diagnosed diabetes in adults. Lifestyle factors play a central role in its development. Type 2 can often be prevented or delayed through healthy habits.
- Gestational diabetes: Develops during pregnancy, affecting how women’s bodies use insulin. While it usually resolves after birth, it increases the mother’s and child’s risk of developing type 2 diabetes.
National Diabetes Prevalence: Latest Numbers
| Category | People Affected | Percentage of Population |
|---|---|---|
| Total people with diabetes | 38.4 million | 11.6% |
| Diagnosed cases | 29.7 million | 8.9% |
| Undiagnosed cases | 8.7 million | 22.8% of diabetics |
| People aged 65 and older | 16.5 million | 29.2% |
| People under age 20 | 352,000 | 0.35% |
Every year, about 1.2 million Americans are newly diagnosed with diabetes. Notably, the prevalence among those over 65 is particularly high, making diabetes a significant concern for seniors.
Prediabetes: An Alarming Epidemic
Prediabetes is a condition in which blood sugar levels are higher than normal but not yet high enough to be diagnosed as type 2 diabetes. Prediabetes increases the risk of developing type 2 diabetes, heart disease, and stroke. Early identification and intervention can prevent or delay the onset of type 2 diabetes.
- 98 million adults (over 1 in 3) had prediabetes in 2021.
- Among adolescents aged 12–18, about 18% have prediabetes.
- More than 80% of adults with prediabetes are unaware of their condition.
| Age Group | Number with Prediabetes |
|---|---|
| 18–44 years | 32.8 million |
| 45–64 years | 37.5 million |
| 65+ years | 27.2 million |
Diabetes by Race and Ethnicity
What others are reading
The prevalence of diagnosed diabetes significantly varies among different demographic groups. Disparities reflect genetic, socioeconomic, lifestyle, and healthcare factors. Below is a demographic breakdown among US adults:
| Race/Ethnic Group | Prevalence |
|---|---|
| American Indian & Alaska Native | 13.6% |
| Non-Hispanic Black | 12.1% |
| Hispanic/Latino | 11.7% |
| Asian American | 9.1% |
| Non-Hispanic White | 6.9% |
Within Asian American groups, prevalence ranges from 6.1% to 12.2% depending on cultural background, highlighting the importance of tailored public health messaging and intervention.
Economic Impact of Diabetes
Managing diabetes carries a significant economic burden. According to recent analyses:
- $413 billion is the estimated annual cost attributable to direct medical expenses and indirect costs (lost work, reduced productivity).
- Individuals with diabetes incur over twice the medical expenses as those without diabetes.
- The economic toll encompasses hospitalizations, medications, supplies, and loss of earnings due to disability, absenteeism, and premature mortality.
Serious Complications Associated with Diabetes
Poorly managed diabetes can result in severe health complications. The most common and serious risks include:
- Blindness: Diabetes is a leading cause of vision loss among working-age adults.
- Kidney failure: High blood sugar damages blood vessels in the kidneys, often leading to chronic kidney disease and dialysis.
- Heart disease and stroke: Cardiovascular disease is the leading cause of death among people with diabetes.
- Peripheral neuropathy: Nerve damage may cause pain, numbness, and may result in limb amputations.
- Poor wound healing and increased infection risk: Especially in lower limbs, which increases the likelihood of amputations.
Key Risk Factors for Type 2 Diabetes
Understanding and addressing risk factors is critical for prevention:
- Being overweight or obese
- Physical inactivity
- Having a family history of diabetes
- Being over age 45
- Belonging to certain racial or ethnic groups at higher risk
- History of gestational diabetes
- High blood pressure or abnormal cholesterol levels
Type 1 vs. Type 2 Diabetes: A Comparative Overview
| Type | Prevalence | Causes | Prevention |
|---|---|---|---|
| Type 1 | ≈5–10% of all cases | Autoimmune: body destroys insulin-producing cells | No preventive strategy known |
| Type 2 | ≈90–95% of adult cases | Insulin resistance and deficiency; influenced by genetics and lifestyle | Often preventable with healthy habits |
Type 1 diabetes is more common in children and young adults, but it can develop at any age. Type 2 diabetes is most common in adults over 45 but is increasingly seen in younger people due to rising obesity and sedentary lifestyles.
Diabetes in Youth: A Growing Concern
- About 352,000 Americans under 20 have diagnosed diabetes.
- Annually, approximately 18,200 youth are diagnosed with type 1 diabetes.
- Annually, nearly 5,300 youth are diagnosed with type 2 diabetes.
- Youth living with diabetes face lifelong health management and increased risk for complications in adulthood.
The Path Forward: Prevention and Effective Management
While type 1 diabetes cannot be prevented, type 2 diabetes can often be delayed or prevented through proactive lifestyle adjustments:
- Adopting a balanced, healthy diet rich in whole grains, fruits, vegetables, lean proteins, and healthy fats
- Engaging in regular physical activity (at least 150 minutes per week for most adults)
- Aim for and maintain a healthy weight
- Managing blood pressure and cholesterol
- Regular health checkups and screenings—especially if you are in a high-risk group
Diabetes is a lifelong condition, but with the right management strategies, people can live active, fulfilling lives. Successful management typically includes:
- Collaborating with healthcare professionals
- Following individualized treatment plans
- Self-monitoring of blood glucose levels
- Medication adherence when prescribed
- Ongoing education about the disease
Frequently Asked Questions
What is the difference between type 1 and type 2 diabetes?
Type 1 diabetes is an autoimmune disease that destroys the insulin-making cells of the pancreas, requiring lifelong insulin therapy. Type 2 diabetes primarily involves insulin resistance and relative insulin deficiency, often managed with lifestyle, oral medications, and sometimes insulin.
How can I find out if I am at risk for diabetes?
Speak with a healthcare provider about your personal and family medical history, get screened for blood glucose levels, and pay special attention if you have known risk factors such as overweight, family history, or a previous diagnosis of gestational diabetes.
Is diabetes reversible?
Type 1 diabetes is not reversible. Type 2 diabetes can sometimes be put into remission, especially with early intervention, weight loss, and sustained healthy lifestyle changes.
What are the first signs of diabetes?
Early symptoms may include frequent urination, increased thirst, unexplained weight loss, fatigue, blurred vision, and slow-healing sores. Many people have no symptoms, which underscores the importance of regular screening.
How often should I get screened for diabetes?
Screening recommendations depend on individual risk factors. Most adults should be tested every 3 years starting at age 45, or earlier and more frequently if they have risk factors like obesity or family history.
