Coping with pouch inflation while flying can be a concern for those with an ostomy. The main worry is that the pouch might inflate, or "balloon," during a flight due to changes in cabin pressure. Although this hasn't led to needing a change on board for some, the possibility can still be stressful. Here are some helpful tips and insights to make your flying experience more comfortable:

1. Many people with ostomies find that pouch inflation isn't a major issue during flights. The changes in cabin pressure typically don't cause leaks.

2. Consider using a two-piece system, such as those from Coloplast, Hollister, or ConvaTec. This allows you to easily detach the pouch and release any gas in the lavatory, then reattach it.

3. Plan your meals carefully. Before and during the flight, opt for smaller portions and foods that are less likely to cause gas. Common triggers to avoid include milk, other dairy products, carbonated drinks, and any foods that you know tend to produce gas for you.

4. If your pouch does inflate, simply head to the aircraft lavatory to release the gas. Once done, you can return to your seat and relax.

5. Remember that everyone is different. It might take some trial and error with your diet and the type of appliance you use to find what works best for you in preventing ballooning.

6. Always keep spare supplies in your carry-on luggage and plan ahead. With some practice, managing pouch inflation should become a rare or easily manageable issue.
