Hello.
Here I would like to give you some information.
GERD is due to Reflux of Acid produced in the stomach back into the food pipe, in it lead to stomach problem like Heaviness in Epigastric region, fullness in abdomen etc. Not a major issue so need not to worry much.
I shall advice you to avoid spicy and oily food, cut down you tea/coffee intake, include 30 mins of wlk daily, sleep with Head end raised.
For medicine you can consult me in detail with your problem. I shall surely help you.
Wishing you good health.
