Suggest Treatment For Flatulence When Diagnosed With Diverticulosis

I am a 56 year old female. I have a horribly embarrassing problem. I have flatulence that sneaks out, if I feel the gas build up and I try to suppress it; it s already out. I had my gallbladder removed; it was nonfunctioning. My gas issue was ok and now it is back again. Nothing works. It is horrible. I have pockets. I have not been dx with IBS, but divertulosis.
