Thanks for writing your query.
After reading your post, it seems that you might be having gastritis
You should take an antacid like Omeprazole
40mg once a day before meals along with Domperidone
30mg. Digestive enzyme
preparation containing pepsin and fungal diastase twice daily and a probiotic
will have an added beneficial effect.
Following precautions will be helpful :-
1.Avoid spicy and oily foods.
2.Avoid being empty stomach for long periods.
3.Avoid smoking and alcohol, if any.
4.Drink lots of water daily.
5.Avoid gas producing foods like peas, cabbage, legumes, etc.
6.Avoid talking while eating.
7.Avoid eating fast.
I hope this is helpful to you.
