Topic Explanation:
The discussion in the forum revolves around the challenges faced by an individual struggling with ostomy bag leaks and seal issues. The person has been experiencing frequent leaks, particularly around the belly button area, despite trying various products and techniques. They describe their ordeal with different types of leaks, including pancaking (where stool collects at the top of the bag instead of falling to the bottom) and issues with the bag popping off due to excess air. The individual has tried using different types of wafers, barrier strips, and even poking holes in the bag to manage air but has not found a reliable solution. They also mention the use of Questran for bile acid malabsorption and the impact of their diet on the stoma output.

Advice and Helpful Insights:
1. Osto-Ez Vent:
- Consider using an Osto-Ez vent, which allows for controlled release of air from the ostomy bag without risking leaks near the top of the bag.

2. Wafer and Barrier Strip Placement:
- Try cutting the wafer in a way that it does not need to cover the belly button, potentially improving the seal.
- Use Hypafix tape to secure the edges of the wafer to the skin, ensuring it sticks well even after showering.

3. Support and Skin Preparation:
- A larger support belt might help by applying even pressure around the wafer, enhancing the seal.
- Ensure the skin is clean, dry, and free from any residues (like lotions or soaps) before applying the wafer. Products like Cetaphil soap are recommended for cleaning the skin around the stoma.

4. Diet and Sleeping Position:
- Adjust your diet to manage pancaking and ballooning, which can be influenced by the types of food consumed.
- Train yourself to sleep on your back with the upper body slightly elevated to help the contents flow to the bottom of the bag and reduce pressure on the wafer.

5. Product Selection and Testing:
- Consider taking a product selection test from ostomy appliance manufacturers like Coloplast to find the most suitable appliance for your needs.
- Experiment with both one-piece and two-piece systems to see which provides a better seal and lasts longer.

6. Showering Techniques:
- Avoid hot showers as they can cause sweating that may loosen the wafer. Use lukewarm water and avoid directing
