I am having stomach flu since 4 days. i am experiencing pain in tummy and have not seen doctor so far. pls help in what is cure and diet?

No crystal ball here: Hard to pinpoint a response, since your question is so nonspecific. Can't even be sure you have a "stomach flu." you may want to consider: what you ate at the time of symptom onset, the location of your symptoms, accompanying distress, exposures to sick individuals, stressors. Definitely see your doctor if symptoms worsen or persist, ; particularly if associated with "alarm signs.".

Agree w Dr. Cattano: Start with clear liquid like water, soda that is clear, or sports hydration drinks. Sip, sip, sip. Work up to solids with bland foods like bananas, rice, applesauce, toast, gelatin, or chicken. Avoid alcohol, nicotine, caffeine, dairy ; high fat foods. Rest. According to the cdc, viral gastroenteritis usually has a duration of one to ten days (depending on the specific virus). Take care.
