Gastric bezoars are rare, cause nonspecific symptoms, and are usually found incidentally in patients undergoing upper gastrointestinal endoscopy or imaging [1]. This topic will review the epidemiology, pathogenesis, clinical manifestations, diagnosis, and management of gastric bezoars.


A gastric bezoar is defined as a foreign body resulting from accumulation of ingested material, most commonly found as a hard mass or concretion in the stomach.

Bezoars are classified according to their composition (table 1) [2-11].

Phytobezoars – Phytobezoars, composed of vegetable matter, are the most common type of bezoar. The diospyrobezoar, composed of persimmon fruit, accounts for the majority of cases.

Trichobezoars – Trichobezoars are composed of hair.
