This topic is about dealing with a blister that has formed under the outer edge of an ileostomy bag seal. The person who discovered the blister is looking for ways to protect or treat it without causing leaks or compromising the adhesion of the bag. Here are some helpful suggestions and insights shared by others:

1. Trim the wafer or baseplate: Carefully cut away a small section of the wafer or base tape so it doesn't press on the blister. Many people have done this around sensitive areas without losing adhesion.

2. Use a protective ostomy powder: Lightly dust the blistered area before applying the wafer. This can help reduce friction and absorb moisture while still allowing the adhesive to stick.

3. Handle changes gently: Be extra cautious when removing the appliance to avoid bursting or worsening the blister. Try to minimize manipulation of the skin.

4. Monitor and consult a stoma nurse: Keep an eye on the blister. If it enlarges, weeps, or looks like hypergranulation tissue, seek professional help. A nurse can provide appropriate dressings.

5. Reduce friction inside the pouch: Consider using a lubricating deodorizer inside the bag to prevent rubbing that can create or aggravate blisters near the stoma or wafer edge.

6. Watchful waiting: Sometimes minor spots resolve on their own if left undisturbed. Only intervene if they grow or become painful.

7. Silver nitrate treatment: This can be used medically on stubborn granulomas or blisters, but it is reportedly very painful and should be reserved as a last resort under professional supervision.
