Food Poisoning Symptoms: When to See a Doctor

Most food poisoning resolves on its own within 1–3 days. But certain symptoms signal a serious infection that requires medical attention — and knowing the difference can be lifesaving, especially for children, the elderly, and pregnant women.

Common food poisoning symptoms

Typical food poisoning symptoms include nausea, vomiting, watery diarrhea, stomach cramps, and low-grade fever. These usually appear 6–24 hours after eating contaminated food and resolve within 1–3 days with rest and hydration. Most cases don't require medical treatment beyond staying hydrated.

When to seek medical attention

See a doctor if you experience: bloody stool or vomit, fever above 101.5°F, signs of dehydration (dry mouth, dizziness, no urination), symptoms lasting more than 3 days, or neurological symptoms like blurred vision or tingling. These can indicate infections from Listeria, E. coli STEC, Botulism, or other dangerous pathogens that require treatment.
