Hi @colleenyoung I have had an ostomy for 5 years. I play tennis 3-4 days per week and am quite active and shower most days. I use a one piece appliance and it previously lasted 5-6 days before it needed changing. Recently it needs changing after 3 days. I use a Sensura one piece convex # 15606. I have tried protective shields, barrier paste, and elastic barriers. What is the ‘normal’ time between appliance changes?
