What is a peptic ulcer?
A peptic ulcer is a sore in the lining of the stomach or the first part of the small intestine.
Symptoms, causes and assessment
Helicobacter pylori infection and some pain relievers are major causes. Upper abdominal pain or burning can occur, but symptoms alone cannot confirm it. Testing or endoscopy depends on symptoms and bleeding risk.
Care and when to seek help
Vomiting blood, black tarry stools, fainting or sudden severe abdominal pain requires emergency care. Relying only on acid relief can delay diagnosis; treatment addresses the cause.
