Question: What is (are) Mntriers Disease ?
Answer: Mntriers disease causes the ridges along the inside of the stomach wallcalled rugaeto enlarge, forming giant folds in the stomach lining. The rugae enlarge because of an overgrowth of mucous cells in the stomach wall. In a normal stomach, mucous cells in the rugae release protein-containing mucus. The mucous cells in enlarged rugae release too much mucus, causing proteins to leak from the blood into the stomach. This shortage of protein in the blood is known as hypoproteinemia. Mntriers disease also reduces the number of acid-producing cells in the stomach, which decreases stomach acid. Mntriers disease is also called Mntrier disease or hypoproteinemic hypertrophic gastropathy.

Question: What to do for Mntriers Disease ?
Answer: Researchers have not found that eating, diet, and nutrition play a role in causing or preventing Mntriers disease. In some cases, a health care provider may prescribe a high-protein diet to offset the loss of protein due to Mntriers disease. Some people with severe malnutrition may require IV nutrition, which is called total parenteral nutrition (TPN). TPN is a method of providing an IV liquid food mixture through a special tube in the chest.
