Hi, Thanks for writing your query. After reading your post, it seems that you might be having gastritis as a result of taking painkiller like Ibuprofen. I would advise that you should take an antacid like Omeprazole 40mg once a day before meals. You can also take antacid in gel or liquid form. 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. I hope this is helpful to you. Thanks.
