Over the years, I have had some bleeding around the stoma. It was not until two years ago the person working in an ostomy store told me what I might have been doing wrong. I use the precut wafers and sometimes the wafer will be too close to the stoma causing it to "sever" ever-so-slightly; but because there is irritation, the stoma may bleed. Centering the wafer is very important so that the stoma is not affected. A damp cloth will stop the bleeding and better yet, ordinary ice will work; but this could cause frostbite to the area! I use a damp cloth and it seems to work. Also, changing the wafer every 6 days works for me.
