Not so John! We are invaded from the south by "Wilson's Syndrome". This has nothing to do with copper or ceruloplasmin but is an entity of low body temperature, normal thyroid tests, and confused physicians. They even have their own foundation.

There is quite a bit of literature on this topic but as yet there does not appear to be a clear consensus on whether to put patients on replacement therapy. At the Endocrine Society Meetings 2 yr. ago at two separate "Meet the Professor" sessions on subclinical hypothyroidism the two experts could not agree on whether to treat or watch. This is likely a situation where the physician and patient have make a joint decision. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
