Thank you for your question.
I am Dr Saha, I shall try my best to help you.
Viral gastroenteritis usually passes off in 3-5 days.
Sometimes, it can take a week.
Occasionally, bacterial or parasitic infection can be there.
If the symptoms remain same or gets worse, I would suggest to take an examination by doctor.
You can visit a free clinic.
A stool test, blood work would help to plan treatment.
Meanwhile, please try to keep good hydration.
Take plenty of fluid, oral rehydration solution.
Urine output should be observed.
In dehydration, it will decrease.
Bland soft diet, rice, banana, toast can be taken.
These are usually better tolerated.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
