I KNOW that I am intolerant to both gluten & dairy through my experience and everything I have learned from both this forum and another one. I do wonder, though, about malabsorption. Does it occur all the time (when you have it) or does it come and go? Sometimes, my movements are pretty normal and other times they are more like mud, little pieces (wormlike--no I don't have worms), and are floating, and shiny looking. I do not pass blood, so no concern about an IBD. I guess I wonder if you can have malabsorption at times and then at other times, not? I had my vitamin levels checked about a year ago and they were fine. Right now, though, I am taking additional vitamin D since that is too low.
