Ulcer
A sore in the stomach or duodenal lining, causing burning pain that often changes with eating. Ulcers require medical diagnosis and treatment.
What to know
Peptic ulcers are commonly linked to H. pylori infection or to long-term use of certain painkillers. The pain often has a rhythm around meals, and it should always be assessed by a doctor rather than self-managed.
Warning signs
Black or tarry stools, vomiting blood, sudden severe abdominal pain, or fainting need urgent medical attention. Once treatment is under way, regular meals, avoiding alcohol and smoking, and steady stress management support healing.

This page is general wellness education, not a diagnosis. Persistent, severe or new symptoms — and warning signs such as blood in the stool, unexplained weight loss, fever, repeated vomiting or anaemia — need a qualified healthcare professional. Our guidance works alongside your doctor's care, never in place of it.
Each condition page clearly states that diagnosis and medical treatment require the advice of a qualified healthcare professional.
