What is a trichobezoar?

A trichobezoar is a type of gastrointestinal blockage formed from the accumulation of ingested hair, often associated with trichotillomania (compulsive hair-pulling) or trichophagia (compulsive hair-eating). These masses can lead to various gastrointestinal complications, including pain, nausea, vomiting, and obstruction. Diagnosis typically involves imaging studies, and treatment may require endoscopy or surgery to remove the bezoar. Addressing the underlying psychological issue is also crucial for prevention.
