What is meant by the term 'lactobezoar'?

The term 'lactobezoar' refers specifically to a type of intestinal obstruction that occurs due to the accumulation of a gelatinous mass formed from undigested lactose, typically in the form of milk or dairy products. This accumulation can block the intestines, leading to symptoms such as abdominal pain, nausea, and vomiting. It is particularly relevant in individuals who may have altered gastrointestinal motility or digestive problems, which can prevent proper breakdown and absorption of lactose.

While the other provided options represent different medical concepts, they do not accurately capture the definition of 'lactobezoar.' Lactose intolerance relates to the body’s inability to properly digest lactose but does not directly pertain to an obstruction. A food allergy involves an abnormal immune response to specific foods and is not synonymous with a mechanical blockage in the digestive system. An infection of the stomach lining, such as gastritis, concerns inflammation rather than a blockage resulting from undigested material. Thus, recognizing 'lactobezoar' as a type of intestinal obstruction helps clarify its specific medical significance.
