Bezoar

Definition:

A bezoar is a ball of swallowed foreign material (usually hair or fiber) that collects in the stomach and fails to pass through the intestines.


Alternative Names:
Trichobezoar; Hairball
Causes, incidence, and risk factors:

Chewing on or eating hair or fuzzy materials (or indigestible materials such as plastic bags) can lead to the formation of a bezoar. The incidence is very low and the risk is greater among mentally retarded or emotionally disturbed children. Generally bezoars are seen in females (approximately 90%) aged 10 to 19.
