Are there medications to stop someone from farthing as i fart a lot?

Maybe: Eating a healthy diet can cause gas due to excess fiber. Since humans don't digest the fiber, intestinal bacteria will eat it and make gas as a byproduct. "Beano" enzyme may help. Another reason is lactose intolerance, in which one can't digest lactose (milk sugar). "Lactaid" tablets help. A third reason is sugar alcohols, like maltitol, that can cause gas. One's doctor can look for other causes.
