What term describes a condition that lasts for a long time or reoccurs?

The term "chronic" refers to a health condition that persists over an extended period, often for months or years. Chronic conditions typically have ongoing effects and can vary in severity and symptoms over time. This classification is important in health science as it encompasses diseases and health issues that require long-term management and care strategies.

In contrast, "acute" describes conditions that occur suddenly and typically resolve relatively quickly, distinguishing them from those that are chronic. "Intermittent" refers to conditions that may come and go or occur sporadically, rather than being a constant presence. The term "sudden" is often associated with the immediate onset of symptoms or a condition, which does not align with the nature of chronic conditions that are characterized by their longevity and potential for recurrence. Thus, chronic is the best term to describe long-lasting or frequently reoccurring health conditions.
