What should I do if I have symptoms of gastroenteritis?
- For vomiting and diarrhea associated with gastroenteritis, it’s going to be important to replace lost fluids. Oral hydration is usually sufficient, if you can keep fluids down. Start with clear liquids, such as water, clear sodas, Gatorade, ice chips, etc. As you are able to keep fluids down, gradually increase intake, starting with crackers or toast. Generally, you won’t feel like eating normally for a few days. Don’t force yourself to eat - wait until nausea subsides.
- For diarrhea, follow the BRAT diet, (bananas, rice, applesauce, apple juice, toast). Avoid dairy, fats, and greasy foods.
- You can try Pepto-Bismol or loperamide (Imodium) with liquids to try to slow down diarrhea.
