diarrhea

This term describes a distressing loss of bowel control that is typically associated with illness, toxicity, or dietary distress. It carries a strong medical connotation but is used frequently in casual conversation to describe a physical state of urgency and discomfort. Because of its visceral nature, the word often evokes a sense of embarrassment or hygiene-related anxiety. It is distinct from constipation, which is its physiological opposite, and is often used as a shorthand for any gastrointestinal upset involving liquid stool.
