I Suffer From Extremely Excessive Flatulence And I Thought It

I suffer from extremely excessive flatulence and I thought it may be down to a gluten intolerance or a lactose intolerance. I cut out dairy and gluten and for a few days had no issues whatsoever however the flatulence has now returned and I’m not sure what to do. Could this be because of the damage I did to my body when I was eating gluten and dairy and will it go away if I just avoid gluten and dairy?
