Frequently asked questions
What is Helicobacter pylori?
It is a bacterium that can inflame the stomach and cause ulcers. It can usually be treated with antibiotics and acid suppression.
Can anti-inflammatory medicines cause ulcers?
Yes. Medicines such as ibuprofen, diclofenac, naproxen and aspirin can increase ulcer and bleeding risk.
How do I know an ulcer has healed?
Symptoms alone are not always reliable. Follow-up testing or gastroscopy may be recommended depending on the ulcer location and cause.
When to seek urgent medical help
Seek urgent medical care for heavy bleeding, vomiting blood, black tar-like bowel motions, fainting, severe or rapidly worsening abdominal pain, persistent vomiting, or significant weakness.
