This topic is about dealing with unexpected odor issues when using a Hollister one-piece ostomy pouch, even when there are no detectable leaks. The person experiencing this is six weeks post-surgery and is concerned about occasional stool odor, which her husband does not notice. She is unsure if the odor is real or imagined, as she has been told that a properly sealed appliance should not smell. Here are some helpful insights and advice:

1. Integrated filters can sometimes release odors.
- You can cover the filter with the white tab provided in the box or use ordinary tape. Be aware that this might cause the pouch to balloon.
- Some people choose to block the filter only when eating foods with strong smells, like fish.

2. Consider using an internal deodorant or lubricant.
- A mix of Hollister Adapt Lubricating Deodorant and Hollister m9 Odor Eliminator Drops (in a ¾ to ¼ ratio) is said to help reduce odor while maintaining adhesion.
- Generic deodorizer sachets or liquid drops can also help mask any lingering smells and provide peace of mind.

3. Be cautious with alternative lubricants.
- Revel “It’s In The Bag” lubricant, which is oil-based, may leave oily stains on fabric covers and clothing, degrade pouch filters, and cause barrier rings to absorb more output, leading to earlier odor or leakage.
- Pure coconut oil and some flavored lubricants can weaken adhesive strength and promote odor, so they are best reserved for pouch removal rather than regular use.

4. Phantom or "nose-locked" smells are common among new ostomates.
- Anxiety can make you more aware of smells. If your partner cannot detect the odor and there is no leakage, it might just be lingering in your nasal passages.

5. Wafer and hydrocolloid absorption can create odor over time, even without a visible leak.
- Moisture from output is slowly absorbed, and by the second day, some users notice a smell despite an intact seal.
- More frequent changes or switching to a two-piece system with adhesive coupling, which is reported to smell less than mechanical coupling, can help.

6. Product or batch quality can affect odor.
- Some people have experienced entire lots of Hollister CerraPlus pouches that leaked or smelled prematurely. Inspect each bag before use and request a replacement if problems persist.

7. Dietary triggers like fish and other strong-smelling foods can reliably create odor.
- Plan to change the pouch sooner after consuming these foods.

8. Closed-end pouches can help avoid residual waste on the outlet.
- Some users switch to them when odor persists despite thorough cleaning.

9. General reassurance: Most new ostomates worry about odor, but this concern usually diminishes with experience and routine refinement.
