On week 37, part 5, Chris talks about patients who have low TSH and low T3 and T4 that this can be caused by Hashimoto’s or pituitary gland or hypothalamic dysfunction. Can this occur with HPA axis dysfunction as well?

Dr. Amy Nett:  So HPA axis dysfunction can certainly cause low thyroid function potentially, also low T3 and T4, it depends on the degree. But absolutely if we’re talking about relatively low TSH, then I would think about HPA axis dysfunction.
