Primary Outcome Measures:
- presence of celiac disease [ Time Frame: 1 month ]
Secondary Outcome Measures:
- Symptoms associated with celiac disease [ Time Frame: 6 months ]
a short questionnaire will be filled out at the time of serologic testing. If a patient hads celiac disease the form will be filled out again at 6 months after diagnosis.
- medication adjustment [ Time Frame: 6 months ]
Patients diagnosed with celiac disease who initiate a gluten free diet will be assessed to determine whether adjustment of levothyroxine dosing is necessary
This study is looking at whether hypothyroid patients who require above 125 mcg/day (or >1.5mcg/kg/day) of levothyroxine are more likely to have celiac disease than those who require smaller doses. It also looks to see if the prevalence of celiac disease in hypothyroid patients who require elevated doses of levothyroxine is high enough to warrant screening in that population.
