Stomach ulcer

A stomach ulcer is a sore in the lining of the stomach or duodenum. Helicobacter pylori and anti-inflammatory painkillers are the main causes. Vomiting blood, black stools or sudden severe abdominal pain are warning signs.

• Burning, gnawing or aching pain in the centre of the upper abdomen.
• Pain that changes temporarily with eating and returns later.
• Complete the full Helicobacter pylori treatment and have a test to check that the infection has gone.
• Do not use additional anti-inflammatory painkillers without advice; check non-prescription products too.
• Make an appointment within a few days for recurring upper abdominal pain, night-time pain or symptoms while using painkillers.
• For urgent GP care outside office hours, call HAP 9252. Call Ambulance 912 only for an immediate threat to life.
