Hello! Thanks for putting your query in HCM. I am a Gastroenterologist (DM).
I think you are suffering from acute infectious enteritis
. For which this is all what you have to do:
1.A course of antibiotics like ofloxacin
2. Take lots of liquid to maintain hydration level
3. Regular ORS
If not improved in three days , then visit a Gastroenterologist
I hope I have answered your query and this will help you. Remain in touch and get-well soon
