A<unk>  is a type of bezoar, or trapped mass in the gastrointestinal system, that consists of components of indigestible plant material, such as fibres, skins and seeds. While<unk> s may be discovered incidentally on barium x-ray or endoscopic testing of the stomach, individuals with<unk> s may develop symptoms: nausea, vomiting, gastric outlet obstruction, perforation, abdominal pain, and bleeding have been reported. Conditions that lead to decreased motility in the stomach (gastroparesis) and surgeries on the stomach (such as vagotomy or gastric bypass) are associated with the development of<unk> s. A specific type of<unk> , termed a diospyrobezoar, is associated with ingestion of unripe persimmons, which contain a soluble tannin called shibuol that polymerizes into a coagulative cellulose-protein compound in the acid environment of the stomach, to form the bezoar. In addition to their presence in human stomachs,<unk> s have been documented in the stomachs of slaughtered plant-eating animals.
