Colostomy - love mine - works great.
I have trained myself to watch what I eat and to take magnesium every evening so that I only have output once a day in the morning. I have very few noise issues, I watch what I eat if I am going to be in a group. I tried every pouch on the market before I decided which one worked best for me. My choice was convenience, closed end, I also DON'T
use any other product including skin prep, removers, paste and glue etc. A couple of times a week I take off my pouch to allow my skin to have air. When I change my pouch I only use baby-wipes, fregrance and alchole free to clean the stoma area. I have had very few leakage problems , I make sure my bag is on secure from the start.
My colostomy has allowed me to lead a normal life - I had IBS and diverticulitis.
Hope this helps - I like being a bagger instead of a flusher.
