Hi,
Thanks for writing your query.
After reading your query, it seems that you might be having increased gas production in the stomach, which may be due to infection of the gastrointestinal tract.
You may take antacid like 
Omeprazole 40 mg once a day before meals along with 
Domperidone 10 mg. Antibiotic like 
Ciprofloxacin 500 mg twice day along with antiamoebic like 
Metronidazole 400 mg  thrice a day will help to control the infection.
Probiotic along with digestive enzymes containing pepsin and fungal diastase will have added beneficial effect.
You should take light diet with less spice and oil prepared under hygienic conditions.
Following precautions will be helpful :-
1. Avoid spicy/oily foods.
2. Do not miss a meal.
3. Avoid gas producing foods like peas, lentils,cabbage, etc.
4. Do not eat fast and do not talk while eating.
5. Avoid emotional/mental stress.
6. Drink at least 8-10 glasses of pure water daily.
I hope this is helpful to you.
Regards. Thanks.
