The 10 Most Common Diseases

1. Heart Disease
   The leading cause of death worldwide, heart disease includes coronary artery disease and heart attacks. Risk factors include high blood pressure, high cholesterol, smoking, and lack of exercise.
2. Stroke
   Often caused by blood clots or bleeding in the brain, stroke can lead to long-term disability. Controlling blood pressure and maintaining a healthy lifestyle lowers risk.
3. Chronic Obstructive Pulmonary Disease (COPD)
   COPD, which includes emphysema and chronic bronchitis, makes breathing difficult and is often linked to smoking and long-term exposure to lung irritants.
4. Lower Respiratory Infections
   Pneumonia, bronchitis, and influenza remain among the most common infectious diseases worldwide, especially affecting young children and older adults.
5. Alzheimer’s Disease and Dementia
   These conditions affect memory, thinking, and daily functioning, with age being the biggest risk factor. Supportive care and early detection are crucial.
6. Diabetes
   Diabetes occurs when the body cannot properly regulate blood sugar. Type 2 diabetes is strongly linked to diet, lifestyle, and obesity.
7. Kidney Disease
   Chronic kidney disease can progress silently until severe damage occurs. Managing blood pressure and diabetes is key to prevention.
8. Liver Disease
   Conditions like cirrhosis and hepatitis can damage liver function. Alcohol use, viral infections, and obesity are common causes.
9. Hypertension (High Blood Pressure)
   Known as the “silent killer,” high blood pressure often shows no symptoms but significantly raises the risk of heart disease and stroke.
10. Parkinson’s Disease
    A progressive neurological disorder that affects movement, Parkinson’s causes tremors, stiffness, and balance problems. While not as common as heart disease or diabetes, it remains a major chronic condition worldwide.
