Diagnosis of Hypothyroidism and Changing Upper Limits for TSH Levels

Dr. Bianco recently published the book, Rethinking Hypothyroidism: Why Treatment Must Change and What Patients Can Do. 

Today I'll be speaking to Dr. Bianco, whom I deeply respect,  about his approach to thyroid health—and mine. 

While we already had a lot of overlap in our approaches,  I walked away with new, incredible insights on hypothyroidism. 

I think you'll feel the same way.

Dr. Bianco received his MD from Santa Casa Medical School and a PhD in human physiology at the University of Sao Paulo, in Brazil. He’s the former president of the American Thyroid Association (2015-2016) and author of the book "Rethinking Hypothyroidism" . 

Currently, he’s a Professor of Medicine at University of Chicago in the research unit called the Committee on Molecular Metabolism and Nutrition which focuses on thyroid hormone metabolism, more specifically, how certain enzymes called deiodinases control thyroid hormone action & metabolism. This research forms the basis for his understanding of the variable response to thyroid hormone replacement among individuals. 

He has been published in over 200 peer reviewed papers.
