My doctor told me that I need to start taking aspirin every day, but I've been told that aspirin can cause stomach bleeding. Is that true?

Yes, it is true that aspirin can cause stomach bleeding. Aspirin is an anti-inflammatory drug that works by blocking the production of prostaglandins in the body. Prostaglandins are chemicals that help blood vessels to dilate and contract. When prostaglandins are blocked, blood flow to the stomach may be reduced, which could lead to stomach bleeding.
