Trichophagia (Greek: τριχοφαγία, from τρίχα, tricha “hair” + φάγειν, phagein “to eat”) is the compulsive eating of hair associated with trichotillomania (hair pulling).[1] In trichophagia, people with trichotillomania also ingest the hair that they pull; in extreme (and rare) cases this can lead to a hair ball (trichobezoar).[2]
Signs and symptoms
Trichophagia is characterized by the person eating hair, usually their own; primarily after pulling it out. Most often, hair is pulled out and then the ends of the root bulb are eaten, or occasionally the hair shaft itself. The hair eventually collect in the gastrointestinal tract (on occasion, and depending upon severity of symptoms) causing indigestion and stomach pain.[citation needed] Ritual is a strong factor, and may involve touching the root bulb to the lips, tasting the hair, and occasionally chewing it. Sometimes those with the disorder may even eat the hair of others. In the psychiatric field it is considered a compulsive psychological disorder.[citation needed]
Prognosis
Rapunzel syndrome, an extreme form of trichobezoar in which the "tail" of the hair ball extends into the intestines, can be fatal if misdiagnosed.[2][3][4][5] In some cases, surgery may be required to remove the mass;[6] a trichobezoar weighing 4.5 kilograms (9.9 lb) was removed from the stomach of an 18-year-old woman with trichophagia.[7]
History
Trichophagia is most often covered in the medical literature only "as a rare symptom of trichotillomania"[8] although it was reported in a 16-year-old boy by a French doctor, M. Baudamant, in the 18th century.[8]
