Monique suggested in another thread that it would be interesting to compare notes, to see how many of us have been pleasantly surprised by unexpected additional benefits of following a gluten-free diet.
In my case, for example, I changed my diet in a desperate attempt to stop the uncontrollable D, and the cyclic flu-like symptoms that continued to recycle on a seemingly endless schedule. I was surprised when it also resolved all the other problems, such as the severe arthritis symptoms (that had begun about the time of the onset of my other symptoms). Migraines, headaches, general body pains, and even the recurring mouth sores also disappeared, as my gut healed. Of course, most of those symptoms had only appeared when the disease suddenly went into overdrive.
The interesting part was discovering that skin problems that had plagued me since adolescence, such as recurring fungal infections and occasional boils or other skin eruptions, all eventually went away, and they never came back. I thought that everyone had occasional headaches (and maybe they do), but I haven't had an honest-to-goodness headache since my gut healed, and that was over 8 years ago. The only way I can get a headache now, is to bump my head on something when I'm not paying attention to where I'm going.

If only I had known what I know now, about 30 years earlier.
