Thanks for writing your query.
After reading your post, I would like to advise that you should follow some precautions like :-
1.Avoid being empty stomach for long periods.
2.Avoid spicy and oily foods.
3.Avoid mental and emotional stress
and alcohol, if any.
5.Avoid self medications, especially pain killers and steroids
6.Drink lots of water daily.
5.Eat food prepared under hygienic conditions.
You can take an antacid
in gel or liquid form as it forms a protective coating over the damaged mucosa of the stomach.
I hope this is helpful to you.
