Celiac sprue isn't TMS, its an autoimmune disease in which the villi in the intestine are damaged and flattened from your the sufferer's reaction to gluten. When the sufferer stops eating gluten, the villi heal and symptoms go away.
You know my journey, and from what I've learned this past year and a half since my disc thingie and subsequent healing, I'm a believer that pretty much anything can be a mind/body disorder. . .(I use that term instead of TMS--seems to restrictive). Louise Hay says we [emotions] create every condition in our bodies. Plenty of mind/body docs/authors will agree.
