1. Leaks can be caused by various factors, and once the skin is irritated, the replacement flange may not adhere well. It's important to focus on healing the skin.
2. Check if there have been any changes in the normal routine, weight gain, or if the skin is being prepped correctly before applying the products.
3. Consider using different products if the issue started after changing a product in the routine. Some ostomates have found that a slightly defective product can cause issues.
4. Contact a representative from the company supplying the ostomy products for helpful advice and consider trying a different pouch, such as a one-piece pouch.
5. After several years, the colostomy site may have experienced a curvature from a hernia, which can affect the appliance's adherence. Using tape around the perimeter and seeking advice from a wound nurse can help address this issue.
6. Inquire about the long-term condition of the skin around the stoma and whether the stoma diameter has remained the same over time.
