How common is indigestion in peptic ulcer?

A peptic ulcer is a sore in the lining of the stomach or the first part of the small intestine. It may cause burning or aching upper-abdominal pain, indigestion, nausea, bloating or discomfort related to meals. Some ulcers cause few symptoms until a complication develops.

The underlying cause may include Helicobacter pylori infection or medicines that irritate the stomach lining. Because these symptoms overlap with reflux and other digestive problems, a clinician may need to review your history and arrange suitable tests.

Make an appointment if indigestion is persistent, recurrent, unusually painful or associated with nausea that affects eating. Bring a list of medicines, including non-prescription pain relievers, and mention any previous stomach problems. Your clinician may investigate infection, review medicines and decide whether further examination is needed. Do not start or stop ulcer treatment without advice.

Seek emergency help for vomiting blood, passing black or tar-like stools, sudden severe abdominal pain, a rigid abdomen, faintness or weakness. Repeated vomiting or difficulty swallowing also warrants prompt assessment. These features can point to bleeding or another complication.

Could my medicines or Helicobacter pylori be contributing? Do I need testing for an ulcer or infection? What should I do if the pain changes, and which warning signs require emergency help?
