Thanks for writing your query.
Your symptoms are due to increased acid and gas production.
You should follow a healthy life style and follow some precautions like :-
1. Avoid spicy and oily foods.
2. Donot miss a meal.
3. Avoid emotional/mental stress.
4. Avoid cigarette/alcohol.
5. Donot self medicate especially with pain killers and steroids
Doing yoga and meditation
wil remove stress, if any.
Drink lots of water daily.
You can take Yoghurt or curd, if it suits you, it will be helpful.
You should take antacid Ranitidine
150 mg twice a day before meals along with Domperidone
10 mg after consulting with your treating doctor. Antacid gel forms a protective coating over the mucosa of the stomach and is beneficial.
Also get yourself investigated for H.Pylori.
I hope this helpful to you.
