What is indigestion?

Indigestion, also known as upset stomach or dyspepsia, is a painful or burning feeling in the upper abdomen. Indigestion is not a distinct condition, but it may be a sign of an underlying intestinal disorder such as a peptic ulcer or gallbladder disease.

  • Drinking too much alcohol
  • Use of drugs that may irritate the stomach
