The 10 Most Common Health Problems in America

The United States is one of the unhealthiest developed nations in the world despite spending more on healthcare than any other country. Chronic diseases are highly prevalent, primarily driven by poor diet, lack of exercise, smoking, and other unhealthy behaviors.

Here are 10 of the most common health problems facing Americans today:

1. Heart Disease

Heart disease remains the leading cause of death in the U.S., accounting for 1 in 4 deaths. Coronary artery disease, heart attacks, congestive heart failure, and other cardiovascular diseases kill over 600,000 Americans every year. Major risk factors include high blood pressure, high LDL cholesterol, smoking, obesity, physical inactivity, poor diet, and diabetes. Many of these risk factors are modifiable through lifestyle changes.

Keeping blood pressure and cholesterol in check through medication and dietary changes, avoiding smoking and secondhand smoke, regular cardiovascular exercise, and eating a nutritious, low-sodium diet rich in fruits, vegetables, and whole grains can prevent up to 80% of heart disease cases. Monitoring health metrics through regular checkups allows for early intervention when risk factors become elevated.

2. Cancer

Cancer is the second leading cause of mortality, responsible for nearly 600,000 deaths annually. The most common cancers in the U.S. are breast, lung, prostate, and colorectal cancers. However, incidence and mortality rates vary greatly by cancer type. Widespread screening programs and early detection for breast, cervical, and colorectal cancers, as well as improvements in surgical techniques, radiation therapy, chemotherapy, immunotherapy, and personalized medicine, have led to declining mortality rates for many cancers.

However, obesity-related cancers like uterine, pancreatic, kidney, and liver cancer are rising. Quitting smoking, maintaining a healthy weight, protecting skin from excessive sun exposure, getting recommended cancer screenings, and undergoing HPV vaccination can all help prevent cancer. Public health initiatives aimed at encouraging healthy lifestyles and increased screening participation are key to further reducing the cancer burden.

3. Respiratory Diseases

Respiratory Diseases

Respiratory illness is the third leading cause of death in America. Chronic lower respiratory diseases like COPD, chronic bronchitis, emphysema, and asthma afflict millions of Americans. Cigarette smoking is by far the primary risk factor, accounting for over 85% of COPD deaths. However, air pollution, indoor and outdoor allergens, genetic predisposition, respiratory infections, and occupational chemical or particulate hazards also contribute to chronic lung disease.

Avoiding tobacco smoke exposure, getting annual flu and pneumonia vaccinations, minimizing exposure to industrial irritants and known allergens, wearing masks in poor air quality, and managing conditions like asthma and allergies with regular medical care can all help protect lung health and prevent exacerbations of respiratory illness.

4. Stroke

Stroke is the fifth leading cause of death, killing over 140,000 people annually. Ischemic strokes caused by blood clots are most common. Hemorrhagic strokes caused by bleeding in the brain are less frequent but more often fatal. Major risk factors for stroke include high blood pressure, high cholesterol, smoking, obesity, physical inactivity, unhealthy diet, and diabetes.

Preventive measures involve controlling blood pressure and cholesterol levels, quitting smoking, exercising regularly, limiting alcohol, and eating a low-sodium, high-fiber diet.

5. Alzheimer’s Disease

Alzheimer's Disease

Alzheimer’s is the most common form of dementia, afflicting over 5 million Americans. It leads to memory loss, confusion, impaired judgment, and eventually, loss of independence. While some genetic factors influence risk, the primary drivers are growing older, family history, head trauma, high blood pressure, and heart disease.

Staying physically and mentally active, controlling blood pressure, avoiding head injuries, and keeping socially engaged may help lower Alzheimer’s risk. There is no cure, but early diagnosis allows for better planning and medication management.

6. Diabetes

Diabetes cases have tripled over the past 20 years, affecting over 30 million Americans. 90-95% of cases are Type 2 diabetes, linked to obesity, physical inactivity, and poor diet. It increases the risk of heart disease, stroke, kidney disease, blindness, and limb amputations. Type 1 diabetes is an autoimmune disorder arising in childhood.

Controlling carbohydrate intake, maintaining a healthy weight, exercising regularly, and taking medication as directed can help manage diabetes. Routine screenings allow for early diagnosis and treatment. Also, prescription discounts like BuzzRX can help alleviate the financial burden of diabetes medications and supplies, making management more accessible for those in need.

7. Osteoarthritis

Osteoarthritis is the most common form of arthritis, affecting over 30 million adults. It results from wear and tear on joint cartilage and underlying bone. Symptoms include pain, stiffness, swelling, and decreased range of motion. Knees, hips, and lower back are most impacted. Excess weight, joint injuries, and intense physical activity can increase risk.

Losing weight, avoiding injury, balancing rest and exercise, using proper form, and taking over-the-counter pain relievers can help manage symptoms.

8. Anxiety Disorders

Anxiety disorders like generalized anxiety, social anxiety, phobias, and panic disorders affect over 19 million American adults. These manifest as excessive fear or worry, restlessness, fatigue, irritability, muscle tension, and sleep disturbance. Therapy and medications like SSRIs, SNRIs, and benzodiazepines can help manage symptoms. Lifestyle changes like exercising, meditating, limiting alcohol, and improving sleep habits also support treatment.

9. Depression


Depression is characterized by persistent sadness, hopelessness, sleep issues, anger, and loss of interest in everyday activities. It affects over 17 million Americans, is more prevalent in women, and can lead to suicide. While therapy and antidepressants help many people, lifestyle interventions like exercise, healthy eating, mindfulness, and improving social connections also support treatment and can help prevent recurrence.

10. Obesity

Over 40% of American adults are obese, putting them at higher risk for heart disease, stroke, high blood pressure, diabetes, cancers, and other problems. Obesity results from poor diet, lack of exercise, genetics, and other complex factors.

Losing just 5% of body weight through calorie reduction and 150 minutes of moderate exercise per week can reduce obesity-related health risks. Weight loss medications and bariatric surgery may also be treatment options for some individuals.

The prevalence of preventable chronic diseases highlights the importance of lifestyle choices for long-term health. Quitting smoking, limiting alcohol, reducing stress, improving diet, staying active, and getting health screenings are all small steps anyone can take to live a healthier life. With some changes to daily habits and access to quality preventive healthcare, Americans can work towards a future with lower rates of chronic illness.
