Hi Maggie,
There's a lot being discussed here, so let me try to sort some of it. First off, if you have a lot of loose skin around your stoma, you have a different situation than any of us that don't. Meaning what works for us with tighter skin may not help your situation. Barriers and sealing rings can only deal with so much skin movement. If you have more than they can deal with, none of the solutions we're discussing will work in that situation. I Googled "ostomy products for obese patients" - not that you're obese, but because there must be some solutions for those folks that may be applicable to you with your loose skin. There were a number of sites, but I didn't have time to check them out. I'd suggest you see what they have to offer.
I think some are misunderstanding what you mean when you say you change your bag every day. I take that to mean you are changing your barrier every day, not leaving the barrier in place and just changing the bag (with a 2-piece system). As you're reading, everyone's skin is different. Some have skin that will tolerate being covered by a barrier for days, and others have skin that gets irritated very quickly. The hands-down best thing for irritated skin is to leave it exposed to the air so it can heal. But that's difficult to do with an ostomy. Check out www.nu-hope.com for ostomy products that might work in your situation. If you don't see anything obvious on their site, call them. They are very helpful and might be able to point you in the right direction if they can't help you themselves. Let us know how you make out.
Regards,
Bob
