Aspirin and upset stomach

BMJ Group Medical Reference

Aspirin irritates the lining of your stomach. Most people feel this as indigestion soon after taking an aspirin. Others feel a little sick. More rarely, the irritation causes ulcers or bleeding from the stomach lining. To avoid these problems, take aspirin with your main meal or with a large glass of milk.

But if you think you're having a heart attack, don't worry about your stomach. Chew at least 160 milligrams of aspirin as soon as possible.

If you have an upset stomach or pain after you take aspirin, ask your doctor to recommend a brand that protects your stomach lining.



An ulcer is an open sore. Ulcers can happen in many parts of your body, such as in your stomach, and the skin of your legs, mouth, or genitals.
