what causes extreme flatulence
Extreme flatulence can even interfere with a person's ability to work and socialize comfortably with other people. Most cases of flatulence are related to factors that can be controlled. This is because intestinal gas usually comes from two sources â swallowed air or the work of intestinal bacteria on undigested food. Swallowing air is one cause of flatulence. Although much of this swallowed air is belched upward through the mouth, a small amount passes into the intestines and out through the rectum.
