I have gastroenteritis - when can i eat normally again?

Depends on strain.: Start with clear liquid like water, soda that is clear, or sports hydration drinks. Sip often to prevent dehydration. Work up to solids with bland foods like bananas, rice, applesauce, toast, gelatin, or chicken. Avoid alcohol, nicotine, caffeine, dairy ; high fat foods. You might be able to eat normally as early as a day or two - it depends of strain. Gastroenteritis can last 1 to 10 days. Rest.
