I’m confused about facetious hyperthyroidism presentations because it seems like it can present in a variety of different fashions. For example, there’s been discussion that these patients can have low or low-normal TSH with normal T3 and T4. One elevated and one normal or low or both T3 and T4 high.

Dr. Amy Nett:  So normally, facetious type of hyperthyroidism you see a suppression of T4. So facetious hyperthyroidism most often, you have a lower, low-normal TSH with high T3 and low T4. That’s the most common presentation of facetious hyperthyroidism. And I think we talked about that in week 38 a little bit more. So there’s a little bit more information there that’s still confusing. But look mostly for a low, low-normal TSH and suppression, complete suppression of T4 being most common.
