Medical and anatomical terms have long crossed into everyday English as idioms and metaphors. These expressions, like “bitter pill to swallow,” or “Achilles’ heel", and "a stitch in time saves nine" use medical imagery to describe feelings, conflicts or behaviours. This article lists commonly used medical idioms, explains their meanings and gives short notes on origin and plain-English examples.
Bodies, illness and medical practice are universal human experiences. Medical imagery is vivid and familiar, so it adapts well as metaphor: a “gut feeling” feels immediate; a “pulse” suggests current activity; a “bitter pill” communicates something unpleasant to accept. Language guides and idiom compilations show these patterns across many cultures.
