Q&A With Dr. Richard Bernstein

Do thyroid levels affect how people are able to control their diabetes?

Answer: Well, all that I know is that people who take an excessive amount of liothyronine, which is T3, can raise their blood sugars. The brand name for this medication is Cytomel, and it’s well-known that Cytomel can raise blood sugar if you take too much. So, you have to tighten your serum Free T3 levels to the middle of the normal range.
Does PCOS affect insulin resistance or hypothyroidism?

Answer: As a matter of fact, I just stumbled upon an article which states that young women with PCOS (Polycystic Ovarian Syndrome) apparently have a much higher incidence of hypothyroidism. Also, if they have PCOS, a higher incidence of insulin resistance and diabetes occur. So, these things are tied in together in some strange way.
