Thanks for your question on Health Care Magic.
I can understand your situation and problem.
By your history and description, possibility of gaseous sound due to GERD (
gastroesophageal reflux disease) is more.
Stress and
anxiety are common cause for GERD.
So avoid stress and tension, be relax and calm.
Start
proton pump inhibitors and prokinetic drugs.
It will help in gaseous trouble.
Avoid hot and spicy food.
Avoid junk food. Avoid large meals, instead take frequent small meals.
Avoid
smoking and alcohol if you have these habits. Loose weight if you are obese.
Don't worry, you will be alright.
Hope I have solved your query.
Wish you good health. Thanks.
