L.B.
My son and I both have Celiac disease. Neither of us had gastrointestinal symptoms. Our symptoms were fatique, joint pain and sores on our tongue. My son had a history of iron deficiency anemia prior to diagnosis. I had a history of iron deficiency anemia and B12 deficiency.
My son had the blood test that screens for Celiac. His blood work came back very highly positive. He then had an intestinal biopsy to confirm the diagnosis.
I had the blood test that screens for Celiac and it came back negative, Because my fatique was so bad and I just never felt well, I inisited that the doctor do an intestinal biopsy, I am glad I did because the biopsy came back positive for Celiac.
So the blood test is just a screening and it can give a false negative. Sometimes it gives a false positive that is why it is important to also have the biopsy. Gluten free is not an easy diet and you really don't want to be on it unless you have to.
Yes, you can be deficient on only one vitamin or mineral with celiac, it depends on how severely your intestines are affected.
The only test for gluten sensitivity is trial and error. Many people are sensitive without having Celiac. You can eliminate gluten from your diet completely and see if that makes a difference. Just remember that once you go gluten free you cannot get tested for Celiac because the antibodies will not be in your blood if you are not eating gluten and your intestines will begin to repair themself once you stop gluten intake.
Get the test, then try out a gluten free diet.
Good Luck, let us know what happens
I just want to add you can have celiac disease without having any symptoms.
