Diarrhea

泄泻 〔泄瀉〕xiè xiè

Any deviation from established bowel rhythm characterized by increased frequency of the stool; the semi-liquid or liquid stool characteristic of this condition. Diarrhea occurs in vacuity, repletion, cold, and heat patterns.

Specific types of diarrhea are named in three ways: according to pathomechanism, according to the associated morbid bowel or viscus, and according to signs.

Diarrhea

Classification According to Causes

Classification by Morbid Bowel or Viscus

Classification According to Features

These categories are not mutually exclusive. Food damage diarrhea, for example, is the result of damage to the digestive system by ingested food, as opposed to preexisting dysfunction. It may therefore include certain forms of stomach, large intestine, and small intestine diarrhea, but excludes large intestine diarrhea due to lung qì vacuity.

Association between causes and form of diarrhea is variable. For example, kidney diarrhea is always a form of fifth-watch diarrhea, whereas sloppy diarrhea may be part of either heat or cold patterns.

Etymology

Chinxiè pour, flow, discharge; explained in this context to mean remittent sloppy stool; 泻 xiè, flow, drain; explained in this as meaning defecation like the pouring down of water. The two characters therefore cover the various forms of diarrhea.
