Thanks for your reply and suggestions.
I'm 80 years old and had my ileostomy about 18 months ago. The gas issue seems to be worse now than ever. So, I'll be surprised if it gets better unless I change something.
I had a doctor tell me years ago I must be swallowing air. That was way before the ileostomy and even then I had more gas than most folks. I have tried to catch myself swallowing air, but if I do, I am not aware of it and don't know what to change. I am a very slow eater and chew my food much more than normal.

I have not been able to associate my gas to with any particular food except beans. I'll try to pay attention to broccoli and ice cream as both are very frequent in my normal diet. I'll try eliminating them one at a time. Thanks for mentioning them.

I now use Coloplast pouches with filters, and I tried filtered Hollister pouches earlier. The Hollister filters never seemed to work at all. The Coloplast filters work a little at first, but by day two I think the filter is clogged
