How does aspirin increase the risk of stomach bleeding?
Aspirin can irritate the stomach lining and also reduce the blood’s ability to clot. Together, those effects raise the risk of gastrointestinal (GI) bleeding, which can show up as stomach pain, black/tarry stools, vomiting blood, or anemia.
What symptoms should people watch for?
Seek urgent care if you notice signs of GI bleeding, including black or tarry stools, blood in vomit, vomiting that looks like coffee grounds, dizziness/fainting, or severe weakness. Call your clinician promptly if you have new or worsening stomach pain or symptoms of anemia.
Who is at higher risk for aspirin-related stomach bleeding?
Risk is higher for people with a history of ulcers or GI bleeding and for those taking additional medicines that also affect bleeding or stomach protection, such as other NSAIDs (ibuprofen, naproxen) or blood thinners. Age and other medical conditions can also increase risk.
How do doctors usually reduce aspirin-related bleeding risk?
Clinicians often weigh the heart/stroke benefits against bleeding risk and may adjust the dose, timing, or need for aspirin at all. If aspirin is still needed and bleeding risk is a concern, doctors may use stomach-protective strategies such as prescribing a proton pump inhibitor (PPI), depending on the individual case.
Is “enteric-coated” aspirin safer for the stomach?
Enteric-coated aspirin may reduce direct stomach irritation for some people, but it does not eliminate bleeding risk because aspirin still affects clotting. Many clinicians still consider GI bleeding risk when deciding whether aspirin is appropriate.
What should you ask your doctor to decide if aspirin is right for you?
Ask your doctor:
- Whether you should take aspirin at all for your reason (for example, prevention vs after a heart event).
- Your personal bleeding risk based on your history and current medications.
- Whether you should use stomach protection (like a PPI) and for how long.
- What symptoms would mean you should stop aspirin and seek care.
What happens if you already take aspirin and you’re worried?
Don’t change or stop aspirin without discussing it first if you’re taking it for a heart or stroke indication, but contact your prescriber promptly if you have any bleeding symptoms or a history of ulcers/bleeding.
