Chronic illness refers to long-term health conditions that persist for months or years, often requiring ongoing management. These illnesses can affect various aspects of a person's life, including physical health, emotional well-being, and daily activities. Examples of chronic illnesses include diabetes, asthma, and arthritis. People with chronic illnesses may experience symptoms that fluctuate in intensity, leading to periods of better and worse health. Management often involves a combination of medical treatment, lifestyle changes, and support from healthcare professionals. Understanding and coping with a chronic illness can be challenging for both patients and their families.
