Hello. I Have A Problem Whereas Everything And Anything I

Hello. I have a problem whereas everything and anything I eat gives me bloating for long hours of the day. I feel like my waist size increases and my body temperature starts to rise. This feeling does not go away until I pass wind, which does not happen for a very long time. I'm almost afraid to eat anything because of this feeling. I've tried creon and probiotics but nothing seems to help. Any insight would be helpful.
