Gluten Sensitivity is More Than Just Celiac Disease

If you are a reader of this website, you probably either have Celiac Disease or have a family member or friend that has Celiac Disease. I’m sure by now we’ve all heard the statistic that it is believed roughly 1 in 133 Americans have Celiac Disease.  However, did you know that it is believed that a significantly higher percentage of Americans actually have some form of gluten sensitivity?

If you’d like to learn more about gluten sensitivities, Whole Health Source recently took the time to explain that gluten sensitivity is much more than just Celiac Disease:

Approximately 12% of Americans can be diagnosed as gluten sensitive using blood antibody tests (anti-gliadin IgA or IgG). A subset of these have full-blown celiac disease. The vast, vast majority are undiagnosed. Gluten sensitivity associates with a dizzying array of diseases, including autoimmune disorders, cancer, and neurological problems. The problem with the blood tests is they aren’t very sensitive. The most common blood tests for celiac disease look for a class of antibody called IgA. IgA is produced by the mucosa, including the gut. Unless gut damage is already extensive, the majority of IgA stays in the gut. This may cause the assay to overlook many cases of gluten sensitivity. A negative blood antibody test does not rule out gluten sensitivity!

I recently discovered the work of Dr. Kenneth Fine of EnteroLab. He has developed an assay that detects anti-gliadin IgA in stool. Gliadin is one of the problematic proteins in gluten that is implicated in gluten sensitivity. Dr. Fine has been conducting informal research using his fecal anti-gliadin IgA test (data here). He has found that:

• 100% of untreated celiac patients are antigliadin IgA positive by fecal test, compared to only 76% by blood (n= 17).
• 76% of microscopic colitis (a type of chronic diarrhea) patients are positive by the fecal test, compared to 9% by blood (n= 57).
• 57% of symptomatic people (digestive problems?) are positive by the fecal test, compared to 12% by blood (n= 58).
• 62% of people with autoimmune disease are positive by the fecal test.
• 29% of asymptomatic (healthy) people are positive by the fecal test, compared to 11-12% by blood (n= 240).
• Baby and cow feces are 0% positive by the stool assay.

He also later mentions:

Not everyone who is genetically susceptible will end up developing health problems due to gluten, but it’s impossible to estimate how many of the problems we attribute to other causes are in fact caused or exacerbated by gluten.

If you think you have Celiac Disease, you may actually simply have a gluten sensitivity of some sort, which is why it is so important to go through the proper channels and to get an official diagnosis.
