下痢

1. Origins, structure, and basic meaning

• Structure: Written 下痢 and read げり, it is a digestive symptom involving unusually frequent loose or watery stools.
• Basic usage: It appears after excessive cold food and, when persistent, prompts hydration and a hospital visit.

2. Common pitfalls and similar expressions

• Do not assume one cause
  • Many conditions can produce the symptom, so temporal association with food alone does not prove the medical cause.
