When should I call my doctor about food poisoning?
ANSWER
Though food poisoning usually goes away on its own, call your doctor if you have any signs of dehydration. For example:
- Dry mouth or extreme thirst
- Not peeing much (or at all) or dark, concentrated urine
- Rapid heartbeat or low blood pressure
- Weakness, dizziness, or a lightheaded feeling, especially when going from lying down or sitting to standing
- Confusion
You should also call your doctor if you see any of these symptoms:
- Blood in your vomit or poop
- Blurry vision
- Diarrhea for more than 3 days
- Extreme pain or cramps in your belly
- Fever over 101.5°F
- Throwing up that won’t stop -- you can’t even keep liquids down
- Tingling in your arms
- Weakness in your muscles
Food poisoning is more dangerous for some people than others. It’s best to call a doctor for:
- Adults 60 and older
- Babies and children
- People with a chronic illness or weak immune system
- Pregnant women
