Gases can either be reabsorbed through the gut wall into the circulation and eventually exhaled through the lungs or excreted, better known as a fart.
Farting is a normal part of digestion that reflects the activity of the bacteria in your gut. You might also notice that you fart more when you eat certain foods that are more difficult to digest, such as beans or raw vegetables. While farting every day is normal, farting all the time is not.
The average human unnoticeably farts approximately 25 times during their sleep.
