Celiac disease detection in hypothyroid patients requiring elevated thyroid supplementation: A prospective cohort study.

Background: Celiac disease (CD) is associated with hypothyroidism, but the disease prevalence is not thought to be great enough to warrant testing all hypothyroid patients. We hypothesized that hypothyroid patients with concomitant CD would require elevated doses of levothyroxine, and there is a threshold daily dose, above which, hypothyroid patients should be tested for CD.

Methods: Hypothyroid patients presenting to the endoscopy or endocrinology clinics at the University of Vermont Medical Center were included.
