I have bad smell while passing gas tell me how to remove it?

Dietary changes: Certain foods cause bad odors when passing gas. Eating a diet heavy in red meat is one example. Try cutting out one food at a time from your normal diet, for a week or so, and if you have no improvement, add it back in and cut out another food for a week. Be cautious and see our doctor immediately if you have corresponding changes in your stool.
