I can understand your concern.
Gas can mean many things and everyone has a different defination of gas. For some its acidity and for some its burps and then there are other for whom its farts. Which is your problem.?
Anyways, take a cap. Pantoprazole and levosulpiride combination like cap. Pan-L once or twice a day half an hour before food for 3 days.
Drink lots of water and consult a general physician in person for further evaluation and management if it doesnt subside.
