What is a common characteristic of chronic illness?

A common characteristic of chronic illness is a long duration with possible ongoing treatment. Chronic illnesses typically develop gradually and can last for months or even a lifetime. Unlike acute illnesses, which may have a quick onset and dramatic symptoms, chronic conditions often involve a persistent state that requires regular management and monitoring. Patients may need ongoing treatment to manage symptoms, prevent complications, and improve quality of life. This continuous aspect of care distinguishes chronic illnesses from those that resolve quickly or have a definitive cure.
