Stomach ulcer occurs due to infection with bacteria called H.pylori. Stomach contains a mucus defensive barrier in its wall which provides protection against acid formation. Infection with H.pylori disrupts the mucus layer and thus allows the acid to cause inflammation and ulcer in stomach cells. Upper abdominal pain, bloating, retching and stomach heaviness are the common symptoms of stomach ulcer. Generally antacids and antinflammatory drugs are recommended for the treatment of stomach ulcer. However, in intense conditions, surgery is also suggested.
