Thanks for writing your query.
After reading your post, I would suggest that you should take an antacid
40 mg once a day before breakfast.
If you are having loose stools, you should take an antibiotic like Ciprofloxacin
500 mg twice daily along with antiamoebic like Metronidazole
400 mg thrice a day.
Also have light meals with less spice and oil, prepared under hygienic conditions.
I hope this is helpful to you.
