gas and dressing issues

I have had copd for years and I was wondering if anyone else has these issues? I drink water and juices and for some reason I have so much gas. I burp constantly and have uncontrolled bottom gas. It's
embarrassing and especially in front of the grandkids...also I am struggling to wear a bra anymore. I feel like I'm in a vice and end up unhooking or removing it. I have even bought one in a bigger size, any suggestions please?

Thank you
