I have always sufferred with excess wind. Now that I have to wear a bag the problem is made worse especially at night when the bag inflates like a ballon. Are there any stoma bags on the market that cope with this problem better than others - ie much better filter etcetc.
of the waste might also make it swell up, and like you i wake up to find a huge filled balloon bag. My bag is meant to incorporate a filter system so this doesnt happen but it does, so like you i would be interested in learning what bags are best.
