A bezoar is a gastrointestinal mass developed via the accumulation and hardening of undigested or partially digested materials within the digestive tract. While often seen in the stomach, bezoars are rarely observed in the colon. Although many studies have reported that wholegrain foods have a positive effect on intestinal functions because of their high fiber content, a very limited number of case presentations have reported that excessive intake can cause intestinal obstruction.
