Preventing Dehydration
The best way to prevent dehydration is to drink fluids. It may be difficult to drink and eat during bouts of nausea and diarrhea, but even small amounts help. You can try drinking a few ounces at a time of clear liquids every 15-30 minutes until you can keep larger amounts down. Ice chips can work wonders for dry mouth.Remember, if you think you are dehydrated or at risk of becoming dehydrated, call your doctor. He or she can prescribe medications to relieve vomiting and diarrhea, thus reducing the risk of dehydration. And recommend the right types of fluid to help you re-hydrate. If necessary, fluid can be given via IV.
