I recently had serum, saliva and urine tests to confirm an elevated cortisol diurnal. My ACTH has been elevated for the past 6 months and it has thrown me off w/thyroid meds (Synthroid). I was on 75, then on 50, now on 62.5 consistently for 8+ weeks.
I really don't know what's happening with the ACTH. I've been given an order for a pituitary MRI (no contrast) to see if something is wrong with it, like a pit tumor.
I had sub-clinical Cushing's in the past but it was due to an adrenal adenoma vs the pituitary. Had the one adrenal gland removed. The remaining one remained sluggish so I supplemented Cortef 7.5 everyday since Dx w/Hashimoto's (shortly after surgery). Been that way for about 7 years, and since this episode began in March this year, I had to wean off Cortef and since then I've had very hard time taking Levo even though my cortisol is high.
I remember after the surgery it was such a relief and I was beginning to feel normal again, then 3 months later I was Dx w/Hashimoto's. The doc was weaning me off Cortef but I couldn't handle it once I had started T4 50mcg. I mainly felt dizzy so kept me on the Cortef. I felt sluggish for a long time until I left him (JohnsHopkins, mind you) (typical endo mentality labs only, forget how you feel) and found an integrative doctor and she upped my Levo to 75 and kept me on the Cortef. I finally began feeling better. This went on for years feeling normal. Suddenly this year out of the blue, things began to unravel.
I could not take my medication w/o getting dizzy and feeling off. If this happened, in the past, my doc told me to up my Cortef 2.5. Usually worked and only had to do that for less than a week. So I tried that but to no avail. The doc left and a nurse practitioner took her place. She got labs done and found my ACTH elevated and cortisol high normal. I had to cut back. This was back in March and now I'm off Cortef completely and I have not felt well at all this whole time. I've been taken off levo a couple times and put back on 25/50 and now 62.5. But I can't handle it. It brings me right back to when I was first Dx'd w/Hashimotos and couldn't take Levo w/o Cortef, yet now I'm high normal cortisol, and it's all because of the constant elevation of ACTH.
In the past couple months I've had blood/saliva/urine (DUTCH) test and they all reveal elevated cortisol (with a normal pattern) but they also all reveal a very low DHEA. I have habitually measured low on DHEA for +/-20 years. Always blamed on aging. I'm 56 now. One saliva in 2018 showed <6. A number the doc said she had never seen before. So I supplemented 5mg DHEA. Didn't really help much, because I felt fine and noticed no change. But here I am today with all these tests showing a pattern of a Cortisol/DHEA ratio that is low and all say this is a bad combination.
The DUTCH urine was very revealing. First time I've had that test and the information is more comprehensive than saliva. All sex hormones are low range, glutathione low, melatonin low normal, dopamine low, Cortisol high/Cortisone normal, DHEA low. In this 6 month period, I've lost weight, lost my appetite, nauseous, dizzy, weak, and jittery (never had these jitters before). I have to force myself to eat to maintain 95lbs. My skin is sagging everywhere, like wrinkled and I'm aging before my eyes. I've asked the NP if I should take DHEA a couple months ago, she said no, not now, wait for DUTCH. My iron had dropped to 70 and I asked her if should supplement iron, she said no, but then the next blood test it was 50, so I told her I am going to supplement iron. She's not as dynamic as the prior doctor was. Plus the business seems to have dwindled, so I feel I need to take some matters into my own hands, as I know there's no endo out there who is any good, none that I have ever found.
So my question is this, in regards to DHEA. Does anyone have experience in taking it? It's not mentioned very much in thyroid articles/websites like Cortisol is. Why is that? So not sure how DHEA fits in, and quite frankly never really thought of it because I hardly read about it/hear about it. Does anyone know anything about the Cortisol/DHEA ratio being low? Like symptoms etc. Commentary on Saliva/Urine do say it's a bad combination and I wonder if it has anything to do with why I cannot tolerate thyroid meds.
I've been told I should switch to T3 only yet I've never been able to handle a speck of dust of the stuff. I tried 2.5 a month ago. The first 5 minutes was glorious, my mind cleared, then my heart started racing for about 30 minutes and as it stopped doing that I felt the biggest crash in wellness and I was out of it the rest of the day in misery. I don't understand any of this. But I've been told privately that I don't handle T4 well and my labs show I don't convert well and I should just trudge through dropping it completely and go T3 only. That it's entirely different than Levo and it will also help adrenal problems. The DUTCH said low DHEA can be caused by hypothyroidism. But I do not know how to get passed what T3 does to me. It's like I can't handle any thyroid medications. So I wonder how I got along so well on 75Levo/7.5 Cortef all these years. It's gotta be adrenal related.
Could it all be due the very low DHEA? Appreciate any input. Thank you and sorry for the long post!
