Celiac affects your ability to absorb the nutrients you ingest as it damages the villi in your gut lining. I am not celiac but am gluten intolerant and have not eaten gluten in 11 years. I have several autoimmune issues and there is a connection between autoimmunity and gluten, particularly if you have Hashimoto's, autoimmune hypothyroidism. I also have alopecia for 20 years, treated medically for about 10 years which was like playing wack-a-mole, injecting each new round spot as they appeared each month. During the 10 years of treatment, I never went into remission. When I was diagnosed with osteoporosis, I knew I had to stop treatment but by then I had done a lot of research and new information was coming out on the connection of gluten to autoimmunity. I gave up gluten and within a few months, the alopecia slowed. I then gave up dairy, another inflammatory food for some, and my alopecia went into full remission for the first time and has mostly held for the last 11 years without any medical treatment. I relay this info because I think many with osteo may also have autoimmune issues and if so, it's best to get your microbiome in top shape and avoid inflammatory foods to give yourself the best chance of absorbing all of the nutrients we need to build bone and maintain health.
