The ballooning of the OSTOMY bag should be from gas. Open the bag, I did it at the top and let the gas out. I always taped my bag down, they gave me special tape and a powder, so tape the bag back down and see if that helps. Does this address your issue? Feel free to ask me any questions.

Try a product called EZVent . It really helps you can apply it at the top of your pouch. You can go into a private area and release the gas! I’ve been using it for years! Hope this helps.

Do you have a urostomy or colostomy? I have a urostomy and use coloplast sun suri mio one piece as well as overnight bag. Periodically my bags balloon also. It especially balloons while flying. I disconnected the two bags to let the air out if the overnight bag is ballooning or just emptied the ballooning bag. I have attended other support groups and find it rare for urostomy patients to have this problem. I have been told that it is food related but my diet is fairly consistent and can’t figure out what is causing it.
