Deb,

Sorry to hear about your dad and son and the thyroid issues, and yes, it does run in families.

I don't know if you are aware that there are certain parts of the country that are more prone to thyroid problems because of the deficiency of iodine in the soils in those areas. Mostly in the Mid-west, including MI.

Dr. David Brownstein, MD who has a practice in MI, has written a couple of books that might be helpful: Overcoming Thyroid Disorders, and Iodine, Why you Need It and Why you can't live without it.

Hope that your son will be on replacement hormone (thyroid), and be feeling better in the near future.

Marilyn
