Most forms of chronic nonspecific gastritis do not cause symptoms. However, chronic gastritis is a risk factor
for peptic ulcer disease, gastric polyps, and benign and malignant gastric tumors. Some people with chronic
H. pylori gastritis or autoimmune gastritis develop atrophic gastritis. Atrophic gastritis destroys the cells in the
stomach lining that produce digestive acids and enzymes. Atrophic gastritis can lead to two types of cancer:
gastric cancer and gastric mucosa-associated lymphoid tissue (MALT) lymphoma.
