Trapped Wind (Flatulence)
Flatulence is passing gas from the digestive system out of the back passage. It's more commonly known as "passing wind", or "farting".
There are several natural causes of flatulence. Flatulence can also be caused by some health conditions related to the digestive system, or as a side effect of certain medicines.
Excessive flatulence can usually be treated by making changes to your diet and lifestyle.
