Hard to guess, but..: Since we don't digest the fiber we eat, intestinal bacteria will feed on it and make gas as a byproduct. Another reason could be lactose intolerance, in which one can't digest the lactose (milk sugar) she eats. Again, bacteria will feed on it. Drinking lactose-free milk and eating less fiber, should decrease gas. Intestinal infections, or using antibiotics, can also cause gas. Doctor can evaluate.
