I have Hashimotos and take T3 but simply cannot loss weight. I hardly eat, keep gluten free and what I eat just maintains my weight without losing. If I ate anymore I would continue to gain. I am 18 stone and used to be 10stone. I continue to feel embarrassed by it. I had some private blood tests done and my Cortisol was very high. I went back to my doctor explaining all of this and he ordered a range of tests including cortisol. I had this done today. However the nurse commented this was not a normal set of tests. He had ordered 7 tests including cortisol, TSH and T4 . Vitamin D and B12 but she said the others were for checking heart but I can't remember what they are. Are heart tests normal for suspected Cushings?
