Addison's Disease Support Group
Addison's disease (also known as chronic adrenal insufficiency, or hypocortisolism) is a rare endocrine disorder. It is estimated that it affects about 1 to 2 in 100,000 people. It occurs when the adrenal glands, seated above the kidneys, fail to produce enough of the hormone cortisol and, sometimes, the hormone aldosterone
I would ask for a thyroid panel from the endo too. The sensitivity to cold is a sign of hypothyroidism. I was dx with both Addison's and hypothyroidism at the same time. A lot of the symptoms overlap. If you do get the thyroid tests don't just go by the TSH number. You need to find out what your Free T3 and Free T4 are also. A lot of endo's go solely on the TSH, which really doesn't help if your going to get the right amount of medication to feel better.
I hope this helps. Ask any questions you might have. Hope your feeling better soon.
