Switching to a new ostomy system can sometimes come with a few challenges, especially when it comes to managing gas. If you've recently moved from Hollister pouches to the Coloplast SenSura Mio system and are finding it tricky to release gas, here are some helpful tips and insights that might make things easier:

1. Consider using a SenSura Mio pouch with a built-in filter. Many people find that this feature significantly reduces the need to burp the pouch. However, keep in mind that the filters can clog after a day or two, which might mean you'll need to change the pouch more frequently.

2. Instead of burping the pouch, try emptying it in a restroom. Once it's drained, the pouch will lie flat again.

3. You might want to add an external vent like the Osto-EZ-Vent. This vent adheres to any one- or two-piece pouch, including the SenSura Mio, and allows for quick and mess-free air release without needing to open the tail or top. It doesn't have a filter, works in water, and lasts for the life of the pouch.

4. For discretion under clothing, you can use double-sided dressmaker’s tape along the top edge to help keep the SenSura Mio pouch flat. Light abdominal wraps can also provide gentle pressure, encouraging gas to move through the filter.

5. If you're concerned about the pouch being bulky, you might want to try alternative products like Dansac Nova pouches, which have a low-profile wafer that some users find more discreet under tight or clingy clothing.

6. If you enjoy water activities, you'll be pleased to know that several users have noted the SenSura Mio fabric dries faster than many other brands, making it a good choice for swimming or kayaking.
