Correct Answer: bezoar
a bezoar is an accumulation of indigestible materials in the gastrointestinal tract, most commonly found in the stomach. this mass forms because certain substances that individuals eat cannot be digested by the normal digestive enzymes and processes. as a result, these materials clump together, forming a solid mass that can remain in the stomach for a prolonged period. the presence of a bezoar can lead to discomfort, pain, and other digestive issues, and in severe cases, it may cause a blockage that necessitates medical intervention.
there are several types of bezoars, each classified based on the material that constitutes them. the most common types include trichobezoars, phytobezoars, and pharmacobezoars. trichobezoars are composed of hair - often resulting from a condition called trichophagia, where individuals feel compelled to eat hair. trichobezoars are more commonly seen in young females with psychiatric disorders. phytobezoars, on the other hand, are formed from indigestible plant materials such as cellulose, seeds, or fiber from fruits and vegetables. pharmacobezoars consist of undissolved medication or drug formulations that accumulate in the stomach.
bezoars can cause a variety of symptoms depending on their size and location. common symptoms include nausea, vomiting, gastric ulcers, and even obstruction, which can lead to a serious condition called gastric outlet obstruction. diagnosis typically involves imaging studies such as an abdominal x-ray or ct scan, which can help visualize the mass in the stomach. an endoscopy may also be performed, allowing direct visualization and sometimes removal of the bezoar.
treatment for bezoars varies depending on the type and severity of the condition. in some cases, small bezoars can be managed with changes in diet, increased fluid intake, and medication to enhance gastric motility. larger bezoars might require endoscopic removal, where a scope is used to break down and extract the mass. in extreme cases, surgical intervention may be necessary to remove the bezoar and alleviate the obstruction.
preventing bezoars involves managing the underlying causes, such as addressing dietary habits and treating any psychiatric conditions that may lead to abnormal eating behaviors like pica or trichophagia. regular medical follow-up and psychological support can also be crucial in preventing the recurrence of bezoars.
