Treatment for nausea will depend on what's causing it. Treating an underlying condition (like a milk allergy) can bring relief. Because nausea sometimes is a sign of a medical emergency (such as appendicitis or diabetic ketoacidosis), if a clear cause isn't known, call a doctor right away.
Keep in Mind
Nausea that leads to vomiting or happens with diarrhea can lead to dehydration. It's important to make sure that the fluids, salts, and minerals lost are replaced.
Washing hands well and often is the best way to prevent spreading some of the infections that can cause nausea. Everyone in your family should wash their hands after using the bathroom and before eating or preparing food.
