Topic Explanation:
The discussion revolves around an individual who has transitioned from an ileostomy to a colostomy due to complications such as a parastomal hernia and a minor prolapsed stoma. The person is experiencing a new issue with their colostomy: increased gas noises, which were not present with their previous ileostomy. They are seeking advice on whether this is a normal occurrence or if it necessitates contacting a healthcare professional.

Advice and Insights from Replies:
1. Normalcy of Gas Noises:
- Several participants confirm that it is normal for a colostomy to produce gas noises. These noises can vary from person to person, with some experiencing more noise than others.

2. Handling Social Situations:
- One way to handle the noise in social situations is to acknowledge it humorously, as one participant does by announcing when their colostomy makes a noise and smiling about it.
- Another participant shared that they informed their coworkers about their condition to prevent any misunderstandings about the noises.

3. Dietary Influence:
- The noises can be influenced by what one eats, as noted by a participant whose colostomy noise levels vary with different foods.

4. Biological Explanation:
- It is explained that the colon contains bacteria that produce gas, and since the environment in the small intestine (where the ileostomy was located) is more liquid, it typically produces less gas noise compared to a colostomy.
