I recently got diagnosed with celiac disease and iron deficiency about a year ago. i've been gluten free ever since and i still don't feel better...

Refractory sprue or: ...maybe some gluten is slipping into your diet. If your diagnosis of celiac sprue is a certainty, then checking your tissue transglutaminase antibody now will indicate how successful you may be at gluten avoidance.

Dr Anyanwu agreed

Talk to your Dr: 1) Your doctor can check antibody levels as a surrogate to celiac disease activity. If they are up you may be eating gluten in hidden items (for example if something is fried in oil that also fired wheat containing food). 2) Another consideration is small bacterial overgrowth. Talk to your doctor to see if this fits. 3) Alternatively you may be in the rare group who are refractory to the diet.
