This topic is about a person who has noticed their stoma, which is 9 months old, has started to shrink and dip below the skin level. They are using a specific type of wafer and are seeking advice on why this is happening and how to address it.

Here are some helpful insights and advice:

1. Stomas can naturally change size and "breathe," but if your stoma is sinking below skin level, it might cause issues with adhesion and lead to leaks.

2. Many people suggest trying a convex wafer. This type of wafer helps by pressing the skin around the stoma down, encouraging the stoma to protrude so that the output flows into the pouch properly.

3. It's a good idea to consult your stoma nurse for guidance. They can help you find the right fit and depth for a convex wafer and may provide samples to try.

4. You might also consider using a convex wafer along with an ostomy support belt or hernia belt. This combination can help maintain steady pressure around the stoma, and some people report longer wear times with this setup.

5. Keep in mind that continuous pressure from a convex wafer or belt can cause skin soreness. It's important to monitor the area and adjust or switch products if needed.

6. If you continue to experience leaks or skin issues, it might be time to consult your surgeon or gastroenterologist. In some cases, stoma revision surgery, which involves pulling the stoma out further, might be necessary if other measures don't work.

7. Since nine months is longer than usual for normal post-operative stoma shrinkage, a medical evaluation is recommended if the retraction continues.

8. When seeking help, provide the exact product number of the wafer you are using. This information can help others or suppliers look up the specific type, size, and recommended alternatives.
