I'm glad they put in a referral- I hope it is an endocrinologist who is thorough in their testing. Also, I had a primary care internist order my first pituitary MRI, and I hope you can ask yours to order one for you even before you get to see the endocrinologist! If it turns out you have a pituitary tumor, you might want to visit the brain/pituitary tumor forum, where moderator Rumpled is very consistent at responding to posts and others with pit. tumors check in and give input as well!
I am ging to try and answer both of your questions at the same time...
I am NOT taking any meds for the thyroid nodules. The only thing that has ever been done as far as the thyroid is many blood tests and an ultrasound. The test would come back showing low levels on the thyroid, so they would go back and retest then it would come back normal. Then when I was in a car accident back in April of 2009, and had a MRI of my neck, that's when the nodules where detected, but my doctors never did anything about them, I was the one that questioned it and pursued it.
I have been tested for diabetes and I am quite the opposite. I have HypOglycemia. It was really bad when I was pregnate. My blood sugar stayed in the 40-60 range.
I requested a test for Cushing's. The cortozol level anyways... That DID come back high. I'm not sure if an FSH has been ran though.
My doctors are just now thinking about the pituitary and thyroid since pretty much all else has been ruled out. So they have referred me to an endocrinologist.
As far as my meds, none of them that I am currently on would make my hair fall out. When I was on Methotrexate, my hair did fall out with that to some extent but never this much like it has since I've been off of it.
Have they ever run extensive endocrine tests on you? Besides thyroid function, as Nicola wisely suggested, have you ever been tested for diabetes, Cushing's (easy bruising can come with that), growth hormone, FSH with your amenorrhea? Has looking for a pituitary tumor ever been seriously considered, using a dynamic MRI (with and without contrast)? You have multiple symptoms that I think should cause a doctor to send you to an endocrinologist for a full work up, including if any endocrine numbers come back abnormal, that MRI! And you mentioned visual disturbances- if it started with loss of your peripheral vision, that could be yet another indicator of an abnormal growth on the pituitary.
Also, with the rapid weight gain, did they run any cancer marker blood tests on you?
Regarding the hair falling out- you might check with a pharmacist to see if any medication you are taking could be causing this much hair loss. Stress too can cause a person's hair to fall out, I was told by a doctor... they said it takes about three months before you start to see the affect of the stress with the hair falling out. I had hair falling out with Depakote (about a third of my hair) and again I believe a few months after a car accident. I know it is very difficult to deal with that. I started taking vit B 50 time release, ester c and vit. e for the hair loss at the recommendation of a radio doctor I called into.
You sound like you have a thyroid problem to me all the symptoms can all be thyroid related, I would suggest having a FT3, FT4, TSH. plus a thyroid anti-body blood test.
to check for auto-immune thyroid disease.
I have graves disease, but have just had mt second surgery done ,so i am hypo at the moment, which means under active, and im having symptoms like yours now, loosing my hair, dry skin, the rash, deep voice, joint pain,etc etc.
Also are you taking any thyroid meds, as you say you have thyroid nodules?
When did you last have your thyroid ultra sound scanned?
Sorry if i seem nosey, im just trying to work the picture out, im no doctor, so i can only give light advice, as to were to start.
It sounds like you have had a pretty rough time for the last 13 years, keep getting messed about off different doctors, and being told different diagnosises.
Thyroid illness, can be connected to fibro, pcos,etc.
So it might be worth looking into.
Wishing you well, hope this is off some help to you.
Keep me posted
Nicola.
