This topic is about dealing with changes in ileostomy output, specifically when it becomes thicker and causes issues like seal failures and skin irritation. If you're experiencing similar challenges, here are some possible causes and solutions to consider:

1. It's normal for ileostomy output to thicken over time. As your small bowel adjusts, it might absorb more fluid, leading to thicker output and increased pressure on the wafer, even if your diet hasn't changed.

2. Try a simple food-elimination test. Eat one type of food at a time and observe how your body reacts. This can help identify any foods that might be making your output more acidic or thicker.

3. Improve the fit of your appliance:
- Consider using an ostomy belt for extra support, which can help reduce the strain on the seal.
- Experiment with different types of seals, pastes, or rings. Some people find that certain brands, like Hollister seals, work better for them, while others feel that Eaken rings might not hold up as well under thicker output.

4. Remember that the stinging sensation is due to the natural acidity of the output. Protecting your skin with a good seal and emptying your pouch promptly can help prevent irritation.
