Can aspirin make you feel bloated?
Yes. Aspirin can cause gastrointestinal (GI) irritation, which may lead to bloating or a feeling of fullness in some people. This is part of how aspirin affects the stomach lining and gut. [1]
Why would aspirin lead to bloating?
Aspirin is an NSAID. NSAIDs can irritate the stomach and intestines and may increase the risk of indigestion and other GI symptoms. That irritation can cause symptoms people describe as bloating, gas, or abdominal discomfort. [1]
Does enteric-coated aspirin reduce bloating?
Sometimes it helps with stomach irritation, but it does not fully eliminate GI side effects for everyone. If you still get bloating with enteric-coated aspirin, the issue may still be aspirin-related. [1]
What should you do if aspirin causes bloating?
If bloating starts after you take aspirin, consider stopping and checking with a clinician—especially if symptoms are new, recurring, or severe. It’s also important to avoid taking more aspirin than directed until you’ve discussed it. If you need pain relief, ask about alternatives that may be easier on the stomach. [1]
When to get medical help
Seek urgent care if bloating comes with warning signs like vomiting blood, black/tarry stools, severe abdominal pain, fainting, or trouble breathing. Those can indicate more serious GI bleeding or an allergic reaction. [1]
What other causes can look like “aspirin bloating”?
Bloating can also come from diet (carbonated drinks, high-FODMAP foods), constipation, reflux/indigestion, or other medications. If bloating happens consistently after aspirin, that timing is a strong clue the drug is contributing. [1]
