Chronic diseases are long-lasting health conditions that often require ongoing management. Examples include diabetes, heart disease, and asthma. Unlike acute illnesses, which come on suddenly and are usually short-lived, chronic diseases can persist for years or even a lifetime. They often affect a person's daily life and may require regular medical care and lifestyle adjustments. These conditions can result from a combination of genetic, environmental, and lifestyle factors. For instance, poor diet, lack of exercise, and smoking can increase the risk of developing chronic diseases. Managing these conditions often involves medication, regular check-ups, and making healthier choices to improve overall well-being.
