The topic at hand is about dealing with persistent odors coming from an ostomy pouch. A new member is experiencing constant smells and is curious if the issue might be with the seal of the pouch. They are looking for practical ways to tackle this problem. Here are some helpful tips and insights shared by others:

1. **Check for Leaks**: Odors often result from a poor seal or a small leak around the wafer. This can happen due to pressure from gas, excess liquid, or even sleeping on the pouch, which might open up gaps.

2. **Consider the System Type**:
- One-piece pouches without a working filter can trap gas, leading to leaks. Many people prefer two-piece systems that allow them to "burp" the pouch.
- Filters can clog quickly and let odors escape, so manually burping the pouch might be more effective.

3. **Evaluate Pouch Brand and Model**: Some brands are better at containing odors. For instance, users of ConvaTec have noticed improvements after switching to Sur-Fit Natura drainable pouches. It might be helpful to contact ConvaTec for samples or advice.

4. **Change Frequency**: Changing the pouch daily can significantly reduce odor buildup, and many find that Medicare covers this.

5. **Use an Extra Barrier**: Placing a thin grocery-store produce bag over the pouch can help isolate odors and also serves as a convenient disposal bag.

6. **Deodorants and Lubricants**: Consider adding products like M9 or Brava Lubricating Deodorant to the pouch. Most companies offer free samples if you request them.

7. **Homemade Rinses**: Rinse the bag at each emptying with solutions like:
- A 50/50 mix of water and mouthwash
- A few Tic-Tac mints dropped into the pouch between rinses

8. **Diet and Supplements**: Be mindful of recent diet changes, as foods like asparagus or fish-oil/omega-3 capsules can cause distinct odors that permeate the plastic.

9. **Contact the Manufacturer**: If the odor persists, reach out to the pouch manufacturer. They might be aware of material or chemistry issues with certain lots and can suggest alternative pouches or send replacements.
