Topic Explanation
The discussion revolves around the use of Coloplast SenSura Mio bags, specifically addressing issues with the pre-filters in these ostomy bags. The original poster has switched to this type due to a need for a deeper convex base-plate but is experiencing problems with the pre-filters clogging and causing the bag to balloon. This issue is exacerbated by their very watery output due to having only 3.5 meters of small bowel and an ileostomy. The poster is seeking advice and experiences from others regarding managing these pre-filter issues or finding alternative solutions.

Advice and Insights from Replies
1. Use of Gelling Sachets:
- Consider using sachets that solidify the liquid output to prevent pre-filter clogging. Products like Ileosorb, ConvaTec Diamonds, and Trio Pearls were mentioned as potential options.
- These sachets are added directly into the pouch to gel the contents, which can help manage the flow and reduce the risk of filter clogging.

2. Dietary Adjustments and Medications:
- Some users suggested dietary changes and the use of medications like loperamide to thicken the output and slow down motility. However, effectiveness can vary significantly based on individual health conditions and the extent of bowel resection.

3. Bag and Filter Modifications:
- Some users have experimented with modifying the bags by cutting out the pre-filters or adjusting the placement of the filters to better suit their needs.
- It was also mentioned that Coloplast produces a bag model without a filter (transparent "11484"), which might be an alternative for those who face persistent issues with filter clogging.

4. Availability and Cost Concerns:
- Availability of specific products like gelling sachets can vary by region, and in some cases, they may not be subsidized or readily available. For instance, issues were noted regarding the availability and high cost of these products in New Zealand.
- It was suggested to check with local health providers or stoma nurses to explore the possibility of importing or locally sourcing these products.

5. Personal Experiences with Different Bag Types:
- Some users prefer one-piece bags over two-piece systems due to ease of use and better odor control, although this can vary based on personal preference and specific needs related to stoma care.
