Dear Heera, hello.
The symptoms described by you i.e. discomfort epigastric area with stomach ache and burping are usually present due to increased acidity. H.Pylori is one of the cause,for which you have taken medication.
Other cause include:-
1. Remaining empty stomach for long
2. Eating spicy food
3. Oil rich food
You can judge yourself and take precautions accordingly. Endoscopy
will help to know the damage done if any to your mucosa.
along with Domperidone
Antacids in liquid form,like Digene
gel, are more beneficial as they form a protective coating on the damaged mucosa and give quicker and prolonged relief.
Hope this will be beneficial to you.Thanks.
