I have been no-gluten for about three years now. In my life, I always had gastro-intestinal issues of various kinds, stomach pain, and nausea. For about 20 years I had low-grade constant nausea. I do mean constant, 24/7/365. You learn to live with it. No doctor ever helped me with any of that over the years. although they did on occasion prescribe medication that had terrible side effects and did no good.
Finally I went to an alternative medical practitioner, who did muscle testing and told me I am gluten-intolerant. I had eaten bread every day my whole life; it was my favorite thing. When I went gluten free it was like coming off an addiction, and it was hard, but after the first two weeks I started to feel so much better that I kept it up. Now if I get even a little gluten it makes me feel as if I have the flu for about 2 days.
going gluten free has not made the chronic pain go away but not being nauseous all the time is huge. Plus, I don't know how much worse my pain might be if I were still essentially poisoning myself daily with gluten.
I know some people give no credence to alternative medicine practitioners. But in this case, as in a few others in my life, it was an unconventional practitioner who was finally able to help me with a severe and chronic condition.
If you think there's any chance that gluten could be an issue for you, try going gluten free for a few weeks or months and see. But, you really have to be vigilant!! Just not eating bread is not enough. You have to read every single label, because lots of things have wheat, barley, rye, or triticale in them even if you don't think it would (like soy sauce, for instance). You have to basically stop eating in restaurants. Even salad dressing can have gluten in it. If you don't cut it out totally you won't know if it will help you to go gluten free. And you have to give it a good period of time, not just a couple of weeks. They usually say four to six months, although i had results sooner than that. Now I only get nausea occasionally and when I am stressed. I would never go back to eating gluten.
