After the surgeon lifted all restrictions, I went back to my exercise routine. I always use a Hollister two piece changing every five days. Eventually with increased activity I had a few minor leaks and I could smell them. There would be poo around the stoma when I changed wafers. So I tried rings and then paste with my changes and also extenders. Paste didn't work so well but the rings kept the skin very clean so only one wet wipe to clean. I will always use rings now. I'm not buying extenders as medical tape works well for me with no skin problems. By the way I have an outie stoma which suits using rings. I might try to stretch changes to a week.
