Thanks for writing your query.
After reading your post, it seems that your symptoms are due to gastritis
I would suggest that you should get yourself clinically examined and investigated.
Following investigations may be helpful :-
3. Liver Function Test ( LFT ).
You should take Domperidone
30mg along with Omeprazole
Further medical management can be planned after knowing the reports of the above mentioned investigations.
Following precautions will be helpful :-
1.Avoid spicy and oily foods.
2.Avoid being empty stomach for long periods.
3.Avoid mental and emotional stress.
5.Avoid self medications, especially pain killers and steroids.
6.Drink lots of water daily.
I hope this is helpful to you.
