Burning pain in the middle of the abdomen, persistent indigestion, or frequent bloating are symptoms many people dismiss as minor digestive discomfort — but they may be early warning signs of a stomach ulcer (peptic ulcer). Understanding what causes stomach ulcers and when to seek help can prevent the condition from developing into something more serious.
What causes stomach ulcers?
There are two primary causes:
- H. pylori infection
Helicobacter pylori (H. pylori) is a bacterium that damages the stomach lining, triggering chronic inflammation and ulcer formation. It is one of the most common and treatable causes of stomach ulcers, detectable through a simple breath test, stool test, or blood test. - NSAIDs (non-steroidal anti-inflammatory drugs)
Common pain relievers such as ibuprofen and aspirin can irritate and erode the stomach lining when used regularly or over a prolonged period, leading to ulcer development.
Symptoms that may indicate a stomach ulcer
- Burning or aching pain in the middle or upper abdomen
- Bloating and indigestion
- Heartburn
- Nausea or vomiting
- Pain that temporarily improves after eating but returns between meals or at night
Symptoms that require urgent medical attention:
- Dark or black stools
- Vomiting blood
- Sudden severe abdominal pain
- Dizziness or feeling faint
- Unexplained weight loss
How to prevent stomach ulcers
- Always eat clean, freshly cooked food
- Avoid taking pain relievers continuously over a long period — consult a doctor or pharmacist about alternatives if you rely on NSAIDs regularly
- Quit smoking and avoid alcohol, both of which irritate the stomach lining and slow healing
- If you experience chronic symptoms such as frequent burning stomach pain, vomiting, or black stools, see a doctor promptly rather than managing symptoms on your own
When should you see a doctor?
If abdominal burning or pain is recurring, not improving with lifestyle changes, or accompanied by any of the serious symptoms listed above, do not delay. A gastroenterologist can identify the cause — whether H. pylori, medication-related, or otherwise — and begin appropriate treatment before complications develop.
