Ménétrier's disease causes giant folds of tissue to grow in the wall of the stomach. The tissue may be inflamed and may contain ulcers. The disease also causes glands in the stomach to waste away and causes the body to lose fluid containing a protein called albumin. Ménétrier's disease increases a person's risk of stomach cancer. People who have this rare, chronic disease are usually men between ages 30 and 60. The cause of the disease is unknown.
Ménétrier's disease is also called giant hypertrophic gastritis, protein losing gasteropathy, or hypertrophic gastropathy.
Symptoms include pain or discomfort and tenderness in the top middle part of the abdomen, loss of appetite, nausea, vomiting, diarrhea, vomiting blood, swelling in the abdomen, and ulcer-like pain after eating.
Ménétrier's disease is diagnosed through x-rays, endoscopy, and biopsy of stomach tissue. Endoscopy involves looking at the inside of the stomach using a long, lighted tube that is inserted through the mouth. Biopsy involves removing a tiny piece of stomach tissue to examine under the microscope for signs of disease.
