The topic at hand is about managing and reducing gas buildup in an ostomy pouch, which can cause the pouch to inflate or "balloon." If you're dealing with this issue and have already cut out carbonated drinks, here are some helpful tips and insights to consider:

1. Over-the-counter enzyme aid: You might want to try Beano tablets, which are available without a prescription. They can help reduce intestinal gas.

2. Filtered pouches: Think about using an ostomy bag that has an integrated charcoal filter. Just keep in mind that these filters can stop working if they get wet.

3. Dietary changes:
- Try cutting back on breads, cereals, grains, and pasta. Instead, focus on a high-protein, low-fiber diet to reduce fermentation and gas.
- Pay attention to specific vegetables that might cause gas, like cruciferous or high-fiber ones, and limit them if needed.

4. Probiotics: Consult with a naturopath or healthcare provider to find a probiotic strain that suits your gut microbiome. The right probiotic can significantly reduce gas and improve digestion, especially in the early months after surgery.

5. Swallowed air: Be mindful of habits like chewing gum, which can introduce extra air into your digestive system and lead to more ballooning of the pouch.

6. General rule: Keep track of what you eat and drink, and note any combinations that seem to cause ballooning. Everyone's body reacts differently, but being attentive to your diet is crucial for controlling gas.
