I have been diagnosed with both conditions. All of the research I've read says there is a link between the two. Either Hoshimotos caused the POF or the POF is also another autoimmune disorder. My question is this, should I be tested for Addison's disease as well? Quite a bit of literature says that Hoshimotos, POF and Addison's disease are linked. I also have low DHEA and occasionally have hypoglycemic episodes. If anyone is familiar with this I'd appreciate your input. Thanks in advance!
