This is my first post here so please bear with me. I have been diagnosed with FND but researching the adrenals over the years as this has come up a few times. I don't seem to find I fit into the category of Addison's or Cushing's and I've come up negative on both. I'm not sure I fully buy into the adrenal fatigue thing either. However, it comes up a lot that FND could be caused by surgery, injury or infection and these are things that affect the adrenal glands as well and that does seem to be some connection. Mine is triggered by stress massively. Especially since there a connections with the thyroid looking at previous posts here and therefore links as well endocrinolly. I just wondered what other people thought about this what their experiences and research had brought up?
I wondered whether they could be miscommunication between the pituitary and the adrenals on the negative feedback system on the HPA axis? I gave up coffee about the time I became ill and also oral contraceptives which can all have an impact on blood cortisol levels. Looking at my physiology I think I've had high cortisol throughout my life until I got ill. I'm now 41 and pre menopausal. As the adrenals deal with the oestrogen levels as well has made me wonder if there is some changes in these glands or not detected for some reason.
I also had high stress, surgery and infection prior to becoming ill. Plus childhood stress. Any kind of stress connection in the body should raise question marks over the adrenal system and HPA axis. Looking forward to hearing your thoughts.
