I have been suffering from numerous symptoms for years (fatigue, moodiness, menstual issues, hair loss, digestive issues, etc). I had my thyroid "checked" by GPs and they said it was normal. Recently, I had an endocrinologist test me. He said it was "within range."
But I am older and wiser and left with a copy of my labs this time. My TSH is 3.7 <.35-5.5> and my anti-ATPO is 84.5 <0-60>. My T4 is 1.45 <.89-1.76> and my T3 is 2.54 <2.3-4.2). I realize my T4 looks good and my T3 is just on the low side, but after reading that many women feel best with a TSH of 1.0 or so, I wonder if I am hypothyroid... It would really make sense with all of my symptoms.
But - I've also read (link at bottom) that hypothyroid is associated with a low Sex Hormone Binding Globulin - but mine is high (174 <8-112>), which is associated with hyperthyroid. Is Sex Hormone Binding Globulin really much of a factor in diagnosing thyroid issues and could I still have hypothyroid despite this?
I am going to see another doc, one who seems to be really good at listening and using a combination of labs and symptoms to diagnose/treat. But I won't see her for a few weeks. So just trying to get educated in the mean time.
THANK YOU!
PS - reading all of the information and stories here has been very helpful. I'm quite anxious and knowing I'm not crazy and not alone really helps.
