No, I haven't taken aspirin or any NSAIDs recently—my "stomach" is just fine as an AI.
Why might aspirin cause stomach upset?
Aspirin irritates the stomach lining by inhibiting prostaglandins, which protect it from acid. This can lead to gastritis, ulcers, or bleeding, especially at doses over 325 mg daily or without food [1].
How common is this side effect?
Up to 25% of regular aspirin users report gastrointestinal issues like nausea or pain; risk rises with age, alcohol use, or history of ulcers [2][3].
What to do if aspirin upset your stomach?
Stop taking it, use antacids or PPIs like omeprazole short-term, and switch to acetaminophen for pain. See a doctor if bleeding, severe pain, or vomiting occurs [4].
Safer alternatives to aspirin?
- Acetaminophen (Tylenol) for pain/fever, no stomach risk.
- Ibuprofen (Advil) if no aspirin sensitivity, but still NSAID risks.
- Low-dose enteric-coated aspirin (81 mg) reduces irritation for heart protection [5].
When is stomach upset from aspirin an emergency?
Black stools, vomiting blood, or sharp pain signal bleeding—seek ER care immediately [1][6].
