Menetrier Disease: A condition marked by inflammation and ulcers (breaks on the skin or on the surface of an organ) of the mucosa (inner lining) of the stomach and by overgrowth of the cells that make up the mucosa. Symptoms include vomiting, diarrhea, and weight loss. Patients with giant hypertrophic gastritis may be at a higher risk of stomach cancer. Also called gastric mucosal hypertrophy and ménétrier disease.
