Excess Wind
Wind and flatulence are symptoms responding to excess gas somewhere in the gastrointestinal system.
Wind is a term usually used to describe expelling air from either end - flatulence is from your backside, a belch or a burp is from your mouth.
Both can be embarrassing and if it is continual you should rule out any underlying medical cause by going to your doctor.
You can experience real agonising pain with wind and sometimes it can be mistaken for heart problems.
