In brief: Bacteria make gas

A normal person eating a healthy diet can get flatulent.
One reason is excess fiber. Since humans don't digest the fiber, intestinal bacteria will feed on it and make gas as a byproduct. Another reason is lactose intolerance, in which one can't digest the lactose (milk sugar) he eats. Again, bacteria will feed on it. A third reason is sugar alcohols, like maltitol, that can cause gas & diarrhea.

In brief: Lactose Intolerance

Unable to breakdown lactose leads to increased gaseous production causing the bloat and flatulence.
