What defines a chronic illness?

A chronic illness is defined by its duration and frequency, specifically lasting over a significant period of time or recurring often. This characteristic differentiates chronic conditions from acute illnesses, which are typically severe but brief. Chronic illnesses can persist for months or even a lifetime, affecting the individual’s daily functioning and quality of life.

The notion that chronic illness only impacts elderly patients is misleading, as these conditions can affect individuals of all ages, including children and young adults. Additionally, while some chronic illnesses may be managed with medication, they are not necessarily easily treatable; many require ongoing management, lifestyle changes, and regular medical attention to control symptoms or slow progression. Thus, Option C accurately encapsulates the defining feature of chronic illnesses.
