Gastric Trichobezoar: An Unusual Cause of Anemia.

Trichobezoar is a rare disorder that causes swallowed hair to accumulate in the gastrointestinal tract. It can lead to various gastrointestinal and systemic complications. We report the case of a 16-year-old girl who presented with pallor, chronic lethargy, and unintended weight loss. Initial assessment revealed severe microcytic anemia unresponsive to conventional iron supplementation. A giant trichobezoar was found to be filling the stomach after additional imaging investigation. Previously undetected trichotillomania and trichophagia were present in the patient's history. After the trichobezoar was surgically removed, her anemia and general health significantly improved with multidisciplinary care that included behavioral therapy, psychiatric treatment, and nutritional support. This case emphasizes how crucial it is to include trichobezoar as a differential diagnosis in young adolescents who have unexplained anemia, especially when behavioral or psychological issues are present. Early recognition and multidisciplinary management are crucial to prevent severe complications.
