This topic is about whether the M9 deodorizer, used in ostomy pouches to control odor, might be causing gas buildup. The person sharing their experience noticed that after using M9, their pouch became very tight with gas, a problem that had previously been resolved with medication. They are curious if M9 could be interacting with bacteria in a way that produces gas and are seeking insights from others who might have experienced something similar.

Here are some helpful points and advice shared by others:

1. Some people have found success in managing excessive gas in their pouches by using the botanical supplement Atrantil. They take two capsules before meals, but it's important to do this under the guidance of a doctor or gastrointestinal specialist.

2. One person mentioned they prefer to avoid using antibacterial soaps, except when necessary for wound care or surgery preparation. They feel there isn't enough evidence supporting the long-term safety or effectiveness of over-the-counter antibacterial products. Instead, they use Brava Lubricating Deodorant, which helps with odor without causing gas issues.
