This topic is about managing gas issues for someone using a two-piece Hollister New Image pouching system with a built-in filter. Despite the filter, the pouch often fills with gas, requiring frequent "burping." The person enjoys a diet rich in vegetables, legumes, and grains and is looking for ways to manage gas without drastically changing their diet. They are also curious about whether irrigation or other techniques might help. Here are some insights and advice shared by others:

1. **Filters & Positioning**
- Standing can help keep the filter open longer, while sitting or lying down may cause it to clog, especially overnight.
- Some people choose to replace the pouch when ballooning starts instead of dealing with a blocked filter.

2. **Burping vs. Product Change**
- It's common to "burp" the pouch in the bathroom as needed, and many people do this casually.
- For extreme gas, over-the-counter products like Beano or Gas-X can help reduce it.

3. **Diet & Swallowed Air**
- Consulting with a dietitian who understands gastrointestinal issues can be beneficial. Sometimes, it's about the timing or combination of foods rather than eliminating them.
- Swallowing air can significantly increase gas. To reduce this, avoid gum, candies, straws, smoking, and talking while eating. Eating slowly can also help.
- Foods known to cause gas, such as beans, cucumbers, corn, onions, broccoli, and others, don't need to be eliminated but can be timed for when gas is less of a concern.

4. **Irrigation**
- If approved by a healthcare professional, irrigation is highly recommended. It doesn't stop gas but offers several benefits:
- Eliminates daytime output, allowing the use of stoma plugs that vent gas quietly.
- Keeps filtered pouches functional longer with less output.
- Allows for scheduling activities when the colon is clear.
- The first irrigation session can be supervised by a stoma nurse, and instructional videos are available online.
- Necessary supplies include an irrigation set (cone, tubing, bag), irrigation sleeves/pouches, and optional stoma plugs.

5. **Lifestyle Tips**
- Keep spare pouches handy for quick changes.
- Techniques like awareness training or even hypnosis can help reduce unconscious air swallowing.
- Community forums and online resources offer extensive discussions for further information.
