Managing a stoma that occasionally flattens, or retracts, can be a bit challenging, especially when you're trying to apply an ostomy bag securely. This situation often arises during activities like showering, where the stoma might sit almost level with the surrounding skin, making it tricky to attach the barrier ring and wafer without risking leaks. Here are some helpful insights and advice for dealing with stoma retraction:

1. Temporary retraction is quite normal. Various factors such as heat, cold, moisture, physical activity, inactivity, reclining, or wearing support garments can cause a stoma to shorten or swell. Typically, it returns to its usual length once these conditions change.

2. The heat from a shower can often trigger brief retraction. You can apply the ring and pouch as you normally would; the stoma usually fills the space again as it cools down.

3. Consider using a convex system, like a convex wafer or pouch. The convexity helps press the skin around the stoma down, allowing more of the stoma to protrude. This can improve the seal and reduce the chance of output sneaking under the ring.

4. Stoma behavior can be unpredictable, and it may retract randomly throughout the day or while sleeping. Many people find there is no consistent pattern to this behavior.

5. If convex products are not suitable due to the stoma's location or skin sensitivities, stick with the brand that works for you and experiment with different positioning or accessories. Some people need to avoid convexity or certain adhesives due to allergies.

6. Wearing a hernia support belt or engaging in physical activity can temporarily enlarge or lengthen the stoma, while lying down or relaxing can make it shorten.

7. It's worth noting that some individuals may have allergies to certain brands, and finding the right product can be a personal journey. If you have a specific brand that works for you, it might be helpful to share that information privately with others who are seeking similar solutions.
