Experience with Hirschsprung and or none solid stool

I am wondering if there are any other hueligans that have the Hirschsprung decease. Or people with none solid stool. All my life I have had more or less diarrhea. This is due to the condition I have. And I am desperately trying to find a solution.

I am very pleased with Huël but it tend to make it worse. And I am not sure what to do. Add fibers? Or use less fibers? Pro-biotica does not do the trick.
