The New Thyroid Epidemic

Does it seem like everyone is having problems with their thyroid these days? It’s not your imagination. In doing research for our new book on thyroid disorders, What’s Wrong With My Thyroid? (Amazon October 2013), we found that the ratio of people with potential thyroid troubles has increased from 1 in 13 Americans to 1 in 5. 1 in 5! This number reflects those at risk of having thyroid hormone blood levels outside the functional range.

Laboratory Reference Range TSH: 0.5 – 5.5 (varies from one lab to another)

Functional Reference Range TSH: 1.5-3.5

Doctors  typically will only look at the Laboratory Reference Range.  If their patient’s test results come back negative for thyroid disease then that’s it – the patient does not have a thyroid problem.  We now know that the functional ranges of thyroid hormones are much more helpful in diagnosing a patient especially if they also have thyroid-related symptoms and signs including:
