<<Disclaimer: Verify this information before applying it to your situation.>> The CSA conference this weekend featured an endocrinologist who spoke on problems with CD and thyroid. One thing she did mention is that if you are malabsorbing, there could be problems with how much thyroid you need to take. For those of you having trouble, you might want to run this by your endocrinologist. One person was up to 3 mg. of Synthroid and found out that it was because he was still not absorbing properly. Very important!! Rosalie
