I've been hesitant to write this post, because I don't want to jinx myself. But this site has helped me in so many ways, I feel compelled to share my success.
I suffered with nasal polyps for about two years. During that time my body was under a great deal of stress from thyroid and adrenal issues. My polyps were concentrated on one side of my nose, and kept me from being able to breathe through my nose at all when lying down. I tried a few of the suggestions on this site without any luck, and had given up for the most part.
But about five months ago I stopped eating dairy and gluten to help my thyroid and adrenal problems. After about two months the polyps seemed to loosen one day, and I felt them drain down my throat. It has been three months since then, and I have not felt any sign of their return. I can't be sure what it was that caused the polyps, but because I have tried cutting gluten before without result, I believe it was the dairy. I only hope that this helps someone else solve their polyp problems. I will never take the ability to breathe out of my nose for granted again.
