Excessive gas formation. And scary.

From last 2 months there has been sudden and excess gas formation and remains so throughout the day.There has been change in location due to transferable job.Sometimes I wonder if change in water is the reason.No amount of diet change has helped.I have taken medicines which gave temporary relief.I have started with physical exercise.But things remain the same.Earlier I used to do ok without medicines and exercise.There has been increased flatulence.I also wonder if switching from indian style toilet to western is the culprit.Whatever I eat results to bloated feeling and regular belchs.Early morning flatulence has increased which was never there just a couple of months back.And also after lunch.It is really very depressing and scary.
