What Causes Strong Smelling Flatulence With History Of Gall Bladder Surgery?

Yes, you can. My significant other of 24 years has an uncontrollable gas problem. His farts will kill you. It smells like he has passed a dead possum. So bad that when I came home last night and opened the door to the boat, I had to go outside and vomit. He had gall bladder surgery two years ago, but so have others, what is the problem?
