Husband-wife hypothyroidism

Remember the Bushes? Before they left the Whitehouse they were both diagnosed with Grave’s Disease (hyperthyroidism or overactive thyroid). Well, I recently diagnosed both a husband and wife with hypothyroidism (underactive or low thyroid). Both are being treated with thyroid replacement medicine and are doing well, but we all continue to wonder what causes cluster diseases like this. Probably the most likely explanation is a virus. Or maybe it’s the liberals. (Just kidding. I don’t have a political agenda.)
