Welcome, Joanna, I'm sorry that you're suffering with UC.
My heart goes out to you.
You don't have to worry about
germs and infections, because the stoma is always covered with an airtight pouch. The only time it's not covered is for a few minutes about
once a week to change the wafer/pouch, and that happens at home. I hope that helps put your mind at ease.
Good luck with your consult, and keep us posted!
Cecilia
