I would blame it on the dog, but we don't have one!
Seriously, though, I went through a horrible period of evil wind. I came across an article in a magazine about something called FODMAPS. Looked it up and found lists of certain foods to avoid. I experimented by cutting out these foods for a short time and the wind went. Then gradually, I reintroduced some of the foods with no problem. I haven't researched this to any depth, but worth a look at if you are really windy.
