No, you don’t need to change your ostomy appliance every time you shower. Most people with an ostomy can shower while keeping their appliance on. Just be sure to use gentle, non-irritating soap and water, and avoid scrubbing the area where the appliance sticks to your skin. If you’re concerned about keeping the adhesive secure, you might want to pat it dry gently with a towel. However, if you notice any issues with the appliance or your skin, it might be a good idea to consult with your healthcare provider for personalized advice.
