The original post is almost a year old, but for anyone still interested in other ideas.....

If you have not been screened for gluten sensitivity, you should be!! Your medical problems scream potential for gluten sensitivity. The tests you need to request are antigliadin IgA, IgG. Just be sure they do not substitute a newer similar test, called anti-deamidated gliadin.

Gluten sensitivity is common in many autoimmune diseases... and may be the underlying problem for some with Sjogren's and/or fibromyalgia.

In fact, one person who used to post as debinaz at BrainTalk years ago completely reversed her Sjorgren's disease by removing gluten, casein and soy from her diet... ANA antibodies back to zero, symptoms gone. Her doctor was impressed, and now screens all of his Sjogren's patients for gluten sensitivity and recommends a gluten free diet for those who are postive.

Gluten sensitivity is also associated with several skin disorders, one of which is a blistering rash called dermatitis herpetiformis. Has your dermatologist done a skin biopsy of the surrounding tissue to rule this out?






With all of these risk factors, it is definitely something worth considering. There is more information on diagnostics and other information in The Gluten File. You can scan the right bar from the homepage for topics of interest.

You mentioned many other symptoms that are common in celiac disease/ gluten sensitivity... and please be sure that your B12 level is upper range. A lot of symptoms you mention are symptoms I had with a B12 deficiency.

Doctors often miss this, think low normal B12 levels are ok, etc. B12 deficiency is common, especially in those with autoimmune disease. This can all go together... and frequently does.

Tests for B12 deficiency:
B12 level
homocysteine
methylmalonic acid
