   {peptic ulcer}, (Med.) an erosion of the mucous membrane
      forming the lining of the stomach, duodenum, or lower
      esophagus, originally believed to be due mostly to the
      action of gastric juice. Recently, the bacterium
      {Helicobacter pylori} has been implicated as a causal
      agent in many peptic ulcers. In other cases, the use of
      non-steroidal antiinflammatory agents (NSAIDs) such as
      aspirin are believed to be to blame. Such ulcers may be
      treated with antibiotics or antisecretory agents that
      reduce stomach acidity, or both. Formerly believed to be a
      chronic illness that could only be managed, it is now
      viewed as a curable disease.
