trichophagia
n. the chronic eating of one’s own or other people’s hair (in contrast to trichophagy, the biting of one’s own hair). Often co-occurring with trichotillomania, trichophagia is a relatively rare disturbance that may result in a potentially life-threatening trichobezoar, a mass of ingested hair in the stomach that interferes with gastrointestinal peristalsis. When the trichobezoar develops a long tail that extends into the small intestine, the condition is referred to as Rapunzel syndrome.
