Menetrier disease, also known as giant hypertrophic gastritis, is a rare gastrointestinal disorder that primarily affects the stomach. This condition is characterized by the enlargement of the gastric folds, excessive production of stomach acid, and a decrease in the production of digestive enzymes. When looking for synonyms for Menetrier disease, two terms can be used interchangeably. The first is "giant hypertrophic gastritis", which accurately describes the inflammation and thickening of the stomach lining. The second synonym is "hypoproteinemic hypertrophic gastropathy", which refers to the protein deficiency caused by the disease. Both terms can be used to describe this uncommon condition that affects a small number of individuals worldwide.
