How is a chronic disease defined?

A chronic disease is defined as a long-lasting condition that can be managed or controlled but is typically not curable. This definition highlights the persistent nature of such diseases, which may require ongoing medical care, lifestyle adjustments, and continuous management to help improve the quality of life for affected individuals. Examples of chronic diseases include diabetes, hypertension, and arthritis, all of which can persist over many years or a lifetime, requiring consistent treatment and monitoring.

The other definitions fail to accurately capture the essential characteristics of chronic diseases. For instance, a chronic disease is not a temporary illness; it lasts for an extended period. It is also not exclusive to elderly individuals, as chronic conditions can affect people of all ages. Furthermore, chronic diseases do not resolve quickly; instead, they often require long-term management strategies rather than a quick fix through treatment. Therefore, option B accurately represents the enduring and manageable nature of chronic diseases.
