Why does aspirin upset your stomach?
Aspirin can irritate the lining of the stomach and upper intestines. It also reduces protective prostaglandins, which normally help keep the stomach’s mucus layer intact. That irritation can lead to symptoms such as heartburn, nausea, or stomach pain.
What stomach symptoms are common with aspirin?
People often notice gastrointestinal (GI) discomfort, including:
- burning or pain in the upper abdomen
- heartburn or reflux
- nausea
- indigestion
In some cases, aspirin can cause more serious problems like bleeding or ulcers, especially with higher doses or long-term use.
How can you reduce stomach upset from aspirin?
Common strategies include:
- taking aspirin with food or a full glass of water
- using the lowest dose that works (only if your clinician says that’s appropriate)
- switching to an enteric-coated or buffered product (these may reduce stomach irritation for some people, though they don’t eliminate risk for everyone)
- avoiding aspirin together with other stomach-irritating medicines unless a clinician has okayed it
What makes stomach upset more likely?
Risk goes up with:
- higher doses or frequent dosing
- taking aspirin on an empty stomach
- a history of ulcers or GI bleeding
- older age
- taking other medicines that increase bleeding risk (for example, NSAIDs or blood thinners)
When is stomach upset a warning sign?
Stop aspirin and seek medical care urgently if you notice signs of GI bleeding, such as:
- black, tarry stools
- vomiting blood or material that looks like coffee grounds
- severe or worsening abdominal pain
- dizziness or fainting
Does enteric-coated aspirin work better for the stomach?
Enteric-coated aspirin can reduce irritation for some people, but it’s still an aspirin (so stomach bleeding and ulcer risk are not zero). If you’re getting recurrent symptoms, it’s worth discussing alternatives with a clinician.
Should you take aspirin if you have acid reflux or ulcers?
If you have a history of ulcer disease, GI bleeding, or significant reflux, you should not assume aspirin is safe just because symptoms seem “mild.” Discuss your situation with a clinician before continuing or starting aspirin.
Are there alternatives if aspirin bothers your stomach?
Depending on why you take it (for example, heart protection vs pain), clinicians may recommend different approaches, such as changing the dose/formulation or using another medication. The right choice depends on your medical history and the reason you’re taking aspirin.
