Can I just ask - what is NDT?? (I'm still a bit of a novice with all the terminology)
Re. the DHEA, I can only speak from personal experience. I actually took 7-Ketozyme between October 2012 and January 2013, on the advice of my nutritionist, whom I trust. (She is BANT-registered.) I did a bit of digging around before I committed myself and yes, you are recommended to take it under supervision and need to keep an eye on levels. I did come across information that said that excessive DHEA can cause agitation/acne and excessive hair growth. I am like you and very cautious about taking stuff. At that stage however, I felt I had nothing to lose. (I had been struggling with my health increasingly for about 10 years. Throughout this period my GP had not come up with any answers and the final straw came when I asked my GP for blood tests last June as I knew something was wrong - I felt dreadful- but was refused.) At that point I turned to a local nutritionist for some help. We tested throughout the summer (I also did a 28 day hormone test at the same time) then when the results were in I started on the supplements. I certainly felt no ill-effects from the 7-Ketozyme, and actually along with the other supplements the nutritionist had recommended - some high concentrate fish oils, magnesium and spa tone - I think they kept me "propped up" while my GP finally got round to some sort of diagnosis by Christmas. In fact my GP commented when the results were finally in that it was a wonder I was functioning like I was.
I actually knew about my fatigued adrenals then before I was diagnosed as hypothyroid. I only stopped taking the supplements because the haematologist I was referred to asked me to stop taking them. I didn't ask him why. To be honest there was so much to discuss in the appointment that I didn't question it and because I was starting on a LOT of new medication that I thought would sort me out!! (A diagnosis of hypothyroidism/anaemia/neutropenia and osteoporosis all came in within about a week).
Six months down the line, however, I am still struggling with all of the symptoms I had pre-diagnosis, and I am now just starting to explore adrenal support again with my nutritionist. I'm afraid "the gloves are off". I have had a real struggle again with my GP since diagnosis......and I want my life back ( I feel like I have lost a decade!).
I would be really interested to know more about any other symptoms you have, if that's OK especially as we have such similar adrenal profiles. (You mention a racing heart, I can't say that I have experienced anything like that. )
