Trichophagia

From Wikipedia, the free encyclopedia

Trichophagia is the compulsive eating of hair. Most often, long hair is masticated while still attached to the head and then swallowed. The hair eventually collects in the gastrointestinal tract causing symptoms such as indigestion and stomach pain. A purgative can be given to induce the trichobezoar (hairball) to come out.

Surgery may be required in some instances.
