noncommunicable diseases
Noncommunicable diseases (NCDs) are health conditions that are not caused by infections and cannot be transmitted from person to person. They typically develop over time due to genetic, environmental, and lifestyle factors. Common examples include heart disease, cancer, diabetes, and chronic respiratory diseases. NCDs are a leading cause of death worldwide, often linked to habits like poor diet, lack of exercise, tobacco use, and excess alcohol. Managing these diseases involves lifestyle changes, regular medical care, and prevention strategies to reduce risk factors and improve quality of life.
