Phytobezoar is defined as a mass of indigestible plant material that accumulates in the gastrointestinal tract, causing digestive problems. There are several synonyms for this term, including plant bezoar, vegetable bezoar, and green bezoar. Another synonym for phytobezoar is stomach stone, which refers to the similar hardened and obstructive mass that forms in the digestive tract. These terms are typically used interchangeably to refer to the same condition and are commonly the result of eating too much fibrous plant material, such as fruits and vegetables, or from impaired digestion. If left untreated, phytobezoars can lead to serious complications such as intestinal blockages or perforations of the digestive tract.
