Causes & Risk Factors
Several factors can contribute to Gastric Bezoar.
Gastric bezoars form when indigestible materials accumulate in the stomach and bind together over time.
Gastric bezoars form when indigestible materials accumulate in the stomach and bind together over time. The most common type, called a phytobezoar, consists of plant fibers from fruits and vegetables. Foods like persimmons, celery, pumpkin, and grape skins are frequent culprits because they contain high levels of cellulose and tannins that resist stomach acid breakdown. When these materials aren't properly chewed or when stomach function is impaired, they can clump together into solid masses.
Another type, trichobezoars, form from swallowed hair and are most often seen in people with trichotillomania (compulsive hair pulling and eating).
Another type, trichobezoars, form from swallowed hair and are most often seen in people with trichotillomania (compulsive hair pulling and eating). Pharmacobezoars develop from medications that don't dissolve properly, particularly extended-release tablets or capsules that can stick together. Certain psychiatric medications, iron supplements, and antacids are common offenders in this category.
The underlying problem often involves impaired stomach motility or reduced acid production.
The underlying problem often involves impaired stomach motility or reduced acid production. Conditions like diabetes can slow gastric emptying, giving materials more time to accumulate. Previous stomach surgery, particularly procedures that alter the stomach's shape or function, significantly increases bezoar risk. Reduced stomach acid production, whether from medications like proton pump inhibitors or natural aging processes, also contributes because acid helps break down potential bezoar-forming materials.
Risk Factors
- Previous gastric surgery or stomach procedures
- Diabetes with gastroparesis (delayed stomach emptying)
- Trichotillomania (hair pulling and eating disorder)
- Regular consumption of high-fiber foods like persimmons
- Taking multiple medications, especially extended-release forms
- Reduced stomach acid production
- Poor chewing habits or dental problems
- Dehydration or inadequate fluid intake
- Mental health conditions affecting eating behaviors
- Advanced age with decreased gastric motility
Diagnosis
How healthcare professionals diagnose Gastric Bezoar:
- 1
Diagnosing gastric bezoars typically begins when patients report persistent stomach symptoms that don't respond to typical treatments.
Diagnosing gastric bezoars typically begins when patients report persistent stomach symptoms that don't respond to typical treatments. During the initial examination, doctors often feel for masses in the upper abdomen, though smaller bezoars may not be detectable this way. The patient's medical history provides crucial clues, particularly any mention of unusual eating habits, previous stomach surgery, or medications that could contribute to bezoar formation.

The gold standard for diagnosis is upper endoscopy, where a flexible camera is inserted through the mouth to directly visualize the stomach contents.
The gold standard for diagnosis is upper endoscopy, where a flexible camera is inserted through the mouth to directly visualize the stomach contents. This procedure not only confirms the presence of a bezoar but also reveals its size, composition, and exact location. CT scans of the abdomen can also detect larger bezoars and are particularly useful for showing the mass's relationship to surrounding structures. These imaging studies often reveal a characteristic mottled appearance with areas of different density.

Doctors must distinguish bezoars from other conditions that can cause similar symptoms.
Doctors must distinguish bezoars from other conditions that can cause similar symptoms. Stomach cancer, large polyps, and severe gastritis can sometimes mimic bezoar symptoms. Blood tests may be ordered to check for signs of obstruction or nutritional deficiencies. In some cases, a barium swallow study helps evaluate how well the stomach empties and whether the bezoar is causing any blockage. The diagnostic process usually moves quickly once imaging confirms the presence of an abnormal mass in the stomach.
Complications
- The most serious immediate complication of gastric bezoars is bowel obstruction, which occurs when pieces of the bezoar break off and block the small intestine.
- This condition, known as Rapunzel syndrome when associated with trichobezoars, requires emergency medical attention and often surgical intervention.
- Symptoms of obstruction include severe abdominal pain, vomiting, and inability to pass gas or have bowel movements.
- The risk increases with larger bezoars and those that have been present for extended periods.
- Long-term complications can include chronic inflammation of the stomach lining, ulcer formation, and in rare cases, perforation of the stomach wall.
- Large bezoars can cause persistent nausea and vomiting, leading to dehydration and nutritional deficiencies.
- Some patients develop chronic gastritis or changes in stomach function that persist even after bezoar removal.
- However, most complications can be avoided with prompt diagnosis and appropriate treatment, and the majority of patients recover completely once the bezoar is successfully treated and underlying risk factors are addressed.
Prevention
- Preventing gastric bezoars starts with understanding and modifying the dietary and lifestyle factors that contribute to their formation.
- People at higher risk should be particularly careful about thoroughly chewing high-fiber foods and avoiding large quantities of foods known to cause bezoars.
- Persimmons, especially unripe ones, should be consumed in moderation or avoided entirely by susceptible individuals.
- When eating fibrous vegetables like celery or pumpkin, taking time to chew thoroughly and drinking plenty of fluids helps prevent accumulation.
- For individuals with gastroparesis or delayed stomach emptying, working closely with healthcare providers to optimize treatment is crucial.
- This includes taking prescribed medications consistently, eating smaller and more frequent meals, and choosing foods that are easier to digest.
- People taking medications that slow gastric motility should discuss alternatives with their doctors if bezoar risk is a concern.
- Maintaining good oral health and addressing dental problems ensures proper chewing ability, which is the first line of defense against bezoar formation.
- Those with trichotillomania or other hair-pulling behaviors should seek appropriate mental health treatment to address the underlying condition.
- Regular medical follow-up is especially important for people who have had previous bezoars or stomach surgery, as they remain at higher risk for developing new masses.
Treatment approaches for gastric bezoars depend largely on the size, composition, and symptoms of the mass.
Treatment approaches for gastric bezoars depend largely on the size, composition, and symptoms of the mass. For smaller bezoars, especially those made of plant material, doctors often try dissolving them with enzymes or carbonated beverages. Coca-Cola has gained attention as an unusual but effective treatment because its phosphoric acid can help break down certain types of bezoars. This approach requires patience, as the dissolution process can take several days to weeks with regular consumption of the carbonated drink.
Medications play a role in both dissolving existing bezoars and preventing new ones.
Medications play a role in both dissolving existing bezoars and preventing new ones. Prokinetic agents like metoclopramide help stimulate stomach contractions to break apart and move bezoar fragments. Cellulase enzymes can be particularly effective for plant-based bezoars. For patients with underlying gastroparesis, treating the delayed stomach emptying with appropriate medications is essential for preventing recurrence.
When conservative treatments fail or bezoars cause significant obstruction, endoscopic removal becomes necessary.
When conservative treatments fail or bezoars cause significant obstruction, endoscopic removal becomes necessary. During this procedure, gastroenterologists use specialized instruments passed through an endoscope to break apart the mass and remove pieces. Various techniques include mechanical fragmentation, laser therapy, or electrohydraulic lithotripsy. Large or particularly hard bezoars may require multiple sessions for complete removal.
Surgical intervention is reserved for cases where endoscopic methods prove unsuccessful or when complications like perforation occur.
Surgical intervention is reserved for cases where endoscopic methods prove unsuccessful or when complications like perforation occur. Laparoscopic surgery is often preferred when possible, though open surgery may be necessary for very large bezoars. Recent advances in endoscopic techniques have significantly reduced the need for surgical removal. Post-treatment care focuses on addressing underlying conditions that contributed to bezoar formation and implementing dietary modifications to prevent recurrence.
Living With Gastric Bezoar
Living with a history of gastric bezoars requires ongoing awareness and dietary vigilance, but most people can maintain normal, active lives with appropriate precautions. The key is developing sustainable eating habits that minimize risk while still allowing for nutritional variety and social dining. This means learning to chew food thoroughly, eating smaller portions more frequently, and staying well-hydrated during meals. Many patients find that keeping a food diary helps identify which foods might be problematic for them personally.
