<<Disclaimer: Verify this information before applying it to your situation.>> If you are overweight and are often cold, you should probably get your thyroid checked. These are classic symptoms of an underactive thyroid. As has been mentioned before, there is a significant corelation between celiac disease and tyroid problems. So there may be symptoms from more than one problem, each of which confuses identification of the other. Best of luck, Debra [log in to unmask]
