Re: is this possibly hypothyroidism?
Yes, Mike. Thyroid problems are definitely familial. My mom had it, I have it, and so does my daughter.
Get tested! If you can see your dad's doc, you may have an easier time getting the right diagnosis. There are lots of really stupid MDs when it comes to these disorders, and you don't want one who thinks hypothyroidism is a disease of old ladies... Because it isn't!
