My Daughter has had hypothyriodism since birth, and up until 3-4 years ago was taking medication for it. Since then she has neglected it for the past several years even through 3 very difficult pregnancies. I went with her to her new Endocrinologist yesterday, and she told my daughter that during her exam she couldn't feel her thyriod gland, and told her that she either never had one, or it was " dead", and ordered an ultrasound study of her thyriod. This test has never been done before, why I don't know, but my daughter, and I are both wondering what the term Dead meant, and what this ultrasound study is giong to show? My big question is , What do they do for a dead or missing thyriod?, because my daughter is only 27, So , Is this repairable?
