Hiya, I had a partial thyroid lumpectomy about 11 years ago and have been taking Nutri Thyroid on and off since then when I felt I needed to. About 3 years ago I started having more severe symptoms and was at a loss until I read Dr Peatfield's fantastic book 'Your Thyroid'. My symptoms seemed to be adrenal related so I had a private adrenal test done through Genova Diagnostics. The result was that my adrenal glands were verging on exhausted so I started taking Adreno Lyph Plus which seemed to work well. My problem is during the night when I have terrible nightmares (along with the menopausal and thyroid sweats)! and my temperature is always low along with my heart rate which drops as low as 38 during the night. I went to my doctor, waste of time, surprise surprise, and he tested my cortisol levels and full bloods. Cortisol levels were normal, but I guess it was because I had a blood test in the morning and I believe you need to be tested 4 times during the day because your levels change so much in that time. My cholestoral was high and I've just found out that it can be another symptom of thyroid problems. I would love to hear from anyone who has had adrenal problems and their symptoms and I would also urge anyone who feels that their medication isn't working, to have their cortisol levels checked. I know how difficult it is to get a GP to listen, and even when I showed him my Genova results he mocked them.
