<human>: 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?
<bot>: Yes, it is true that aspirin can cause stomach bleeding. Aspirin is a blood thinner and can increase the risk of gastrointestinal bleeding. So it's important to monitor your health closely if you are taking aspirin regularly. You should consult with your doctor before starting any new medications or supplements.
