Hi all. Just wanted to ask if anyone knew much about low cortisol? I'm due to see the endocrinologist at the hospital for my hypothyroidism and he asked for some tests to be done before I went in. One was for cortisol and it's come back as low, 169 nmol at 9am in the morning. Because of that they now want me to have a short synacthen test to check for addisons but I'm on a waiting list for that now. In the meantime I've been feeling worse day by day, fatigue, weakness, dizziness, abdominal pain and weight loss. I wondered if my level is particularly low or just borederline as the GP didn't really tell me much about it. I guess I just want to know what's wrong with me now as I'm sick of feeling poorly. Sorry for the moan! Any experiences or advice would really be appreciated.
