When an Upset Stomach After a Meal Needs Medical Attention
Health
Food poisoning can cause diarrhea, cramps, nausea or vomiting. The CDC recommends seeking medical care for severe symptoms, including bloody diarrhea, frequent vomiting that prevents you from keeping liquids down, or signs of dehydration.
Signs of dehydration can include urinating very little, a dry mouth or dizziness when standing. Take note of when symptoms began and any meals you suspect, but avoid assuming that the last thing you ate was necessarily the cause.
If symptoms are severe or you are concerned about someone at higher risk, seek advice promptly. The CDC lists other warning signs and guidance for when to see a doctor.
