Thanks for writing your query.
After reading your post, it seems that you might be having infection of the gastrointestinal tract.
I would suggest that you should get yourself clinically examined and investigated.
Following investigations may be helpful :-
1. Stool examination.
2. Liver Function Test ( LFT ).
I would advise that you can take an antacid
40mg once a day along with an antibiotic like Ciprofloxacin
500mg twice daily and Metronidazole
400 mg thrice daily.
will have added benefits.
Further medical management can be planned according to the reports of the above mentioned Investigations.
Eat light meals prepared under hygienic conditions. Also take care of your hydration.
I hope this is helpful to you.
