Re: I'm new to this thyroid stuff
Hi and welcome to the healthboards!
Your TSH indicates hypothyroidism. Please don't worry. It sounds like you don't have many symptoms at all so yours is probably in the very early stage. It's great that your gyn even tested for it. Most doctors won't bother testing until the symptoms are much more severe.
As far as the expense for the meds, your doctor will probably start you out on either Synthroid or Levoxyl and the usual starting dose is 50mcgs (.05mgs). It's a natural synthetic (made in a lab) t4 hormone that your body produces anyway. It's nothing that's going to harm you if taken as prescribed. The cost in the US is around $18-$20 for a 30 day supply.
You'll be surprised when you talk to people about this just how many of your friends and maybe even family have it.
I was diagnosed a year ago with this and unlike you, my doctor tried to make me think all my symptoms were due to stress and depression. Instead of testing me for thyroid disease, he let me get worse and worse. Because of this, it is taking a long long time for me to get well. That's why I think you're lucky.
If you haven't already, read the stickys at the top of the page. They're a lot of reading but well worth it.
Live, Love, Laugh.
