How much gas does the human body release over the course of its life time?

Answer:

The average human releases about one quart, or 1 liter of gas from their intestinal tract per day. That would be about 90 gallons, or 365 liters per year. And if they live to be 75 years old, then they would have released about 6,750 gallons, or 27,375 liters of gas in their lifetime.
