Stoma is full of small blood vessels, so it bleeds easily although it stops quite fast too, try avoid usage of dry cotton or gauze to wipe the stoma. Do not rub too hard on the stoma to avoid bleeding. Clean the skin surrounding the stoma thoroughly to avoid residues of fecal matter stays on the skin which can cause skin soreness (excoriation). Keep fingernails short to avoid injury to the stoma and use gloves.
