An ulcer is a breakdown in the lining of the stomach or the first part of the small intestine. A type of bacterial infection (Helicobacter pylori) is the most frequent cause, but lifestyle factors may also raise the risk. The following preventive steps may ward off a peptic ulcer:

1. Limit alcohol to no more than two drinks daily.
2. Stop smoking or chewing tobacco.
3. If you need to take painkillers, avoid anti-inflammatory drugs (NSAIDs) such as naproxen, ibuprofen or aspirin.
4. Consider, with your doctors approval, paracetamol instead.
