Causes of Bezoars

Bezoars are masses formed in the digestive tract that can lead to blockages. They can result from various factors, including certain dietary habits, previous surgeries, medications, or medical conditions. These causes contribute to the formation of bezoars by affecting the digestion and movement of food through the gastrointestinal system. Identifying and addressing the underlying cause is crucial in managing and preventing bezoar formation.


Types of Bezoars

Bezoars are masses formed of foreign material that accumulate in the gastrointestinal tract. They can vary in composition, with different types classified based on the materials they are composed of. Understanding the various forms of bezoars is essential for accurate diagnosis and treatment.

  • Trichobezoar: A bezoar formed from hair accumulation in the stomach, often seen in individuals with trichotillomania or trichophagia.
  • Phytobezoar: A mass of undigested plant material that can obstruct the gastrointestinal tract, commonly associated with highfiber diets or certain fruits.
  • Pharmacobezoar: Caused by the accumulation of medications or pills in the stomach, leading to potential gastrointestinal issues or blockages.
  • Lactobezoar: A rare type of bezoar composed of undigested milk proteins, typically found in newborns or infants fed with formula.
  • Trichophytobezoar: A combination of hair and plant material that can form a bezoar, potentially causing gastrointestinal symptoms and requiring medical intervention for removal.

Risk Factors

Bezoars are masses formed in the stomach or intestines from indigestible materials. Several factors increase the risk of developing bezoars. Understanding these risk factors can aid in prevention and timely management.

Risk factors for Bezoars:

  • Previous gastrointestinal surgery
  • Poor chewing habits
  • Eating disorders

Diagnosis of Bezoars

Bezoars are typically diagnosed through various methods that help healthcare providers determine the presence of these masses in the digestive tract. Healthcare professionals may use a combination of physical exams, medical history reviews, and imaging tests to diagnose bezoars. 

These diagnostic tools can provide valuable insights into the size, location, and composition of the bezoar, aiding in the development of an appropriate treatment plan. By utilizing these diagnostic approaches, healthcare providers can accurately identify and address bezoars in patients.

  • Physical Examination
  • Medical History Assessment
  • Imaging Studies (Xray, CT scan, ultrasound)
  • Upper Endoscopy
  • Blood Tests

Treatment for Bezoars

Bezoars are solid masses formed in the stomach or intestines, often composed of undigested material. Treatment options for bezoars typically depend on the size, location, and composition of the bezoar. In general, treatment may involve dietary changes, medications, endoscopic procedures, or surgery. Dietary modifications may include increasing fiber intake or avoiding certain foods. Medications can help dissolve the bezoar or improve gastric motility. 

  • Endoscopic removal: A procedure where a flexible tube with a camera is used to locate and extract the bezoar from the digestive tract.
  • Medication: Certain medications can be prescribed to help dissolve the bezoar, making it easier to pass through the digestive system.
  • Enzyme therapy: Enzyme supplements may be used to break down the bezoar, aiding in its digestion and elimination.
  • Surgery: In severe cases or when other treatments are not effective, surgical intervention may be necessary to remove the bezoar.
  • Dietary changes: Adjusting the diet to include more fiber and fluids can help prevent the formation of bezoars and promote their natural passage through the digestive system.
