Hi Shelley, I am a registered dietitian and work with lots of clients that have thyroid issues. Additionally, I myself have a history of hashimotos and thyroid cancer and no longer have a thyroid.
Are you currently on thyroid hormones? If so, what brand/dose? How often do you get your full thyroid panel tested (you want to be sure thyroid antibodies are also tracked)?
The majority of people diagnosed with ‘hypothyroid’ have an autoimmune condition called hashimotos. Typically, if you have one autoimmune disorder you can pretty much guarantee you have another (for example, I also have Reynaud’s syndrome). Also, there is a very good chance you are deficient in Vitamin D – have you had your levels checked?
