Is it unhealthy to hold in flatulence? i do not want to fart when i am on the bus or around other people. but i heard it can be bad for your body to not release gas. what could happen to me if i hold in farts?

Not harmful: While those around you may benefit from your ability to hold gas, there should be no downside for you. The bowel is capable of holding large amounts of solid and gas. Typically gas is produced by the digestion process and is dependent on certain food (think beans), odor may be a result of sulfur compounds (onion, garlic). The gas will want out and most often you can pass at more convenient times.
