Thanks for writing your query.
The symptoms you have mentioned are due to increased acid production in the stomach. This can be due to faulty lifestyle and eating habbits.
You should follow some precautions like :-
1. Avoid spicy and oily foods.
2. Avoid emotional/mental stress
3. Avoid cigarette and alcohol.
4. Donot miss a meal.
5. Donot self medicate especially with pain killers and steroids
You can take antacid
20 mg along with Domperidone
10 mg once a day for relief of your symptoms after getting yourself examined by a gastroenterologist.
You should follow the habbit of clearing your bowels daily preferably in the morning.
Also avoid eating in resturants. Take home made meals prepared in hygeinic conditions.
I hope this is helpful to you.
