Living with Gastric mucosal hypertrophy

Also called Menetrier disease: overgrowth of the stomach lining that causes thick stomach folds, pain, nausea, and protein loss.

Understanding Gastric mucosal hypertrophy

Gastric mucosal hypertrophy, also called Menetrier disease, is a stomach condition in which the lining overgrows.

Overgrowth of mucous cells in the stomach lining makes the stomach folds larger. This leads to extra mucus, protein loss from the stomach, and low or no stomach acid. It can start from childhood to adulthood.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Pain in the upper middle belly
  • Nausea
  • Vomiting
  • Weight loss
  • Swelling in the arms and legs (peripheral edema)
  • Lack of energy and strength (asthenia)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include digestive system specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
