This topic is about someone who is experiencing increased intestinal gas due to blood-thinning medication, which causes their ostomy pouch to balloon. They are looking for an ostomy pouch that can automatically release gas without needing to be manually vented.

Here are some helpful insights and advice:

1. Consider using vented or filtered pouches:
- A recommended option is the Hollister 18393, a pre-cut, one-piece drainable pouch with an integrated carbon filter. This filter allows gas to escape while absorbing odors.
- Keep in mind that filters work well for several hours but can become clogged if stool covers them. Once saturated, the pouch will still require manual venting.

2. Be prepared to manually vent the pouch multiple times a day, even with filtered pouches, as no pouch is completely automatic.

3. Over-the-counter anti-gas medication like Simethicone (Gas-X) can help reduce gas build-up, but users will still need to vent the pouch.

4. Many brands offer pouches with charcoal (carbon) filters. Several users have reported satisfaction with these pouches, although they still require occasional manual release of gas.
