I went in and got my test results today. I thought they tested T1 but it was T3 (triiodothyronine) and T4 (thyroxine).

My T4 was 14.3 with a reference interval of 4.5-12.0
My T3 was 191 with a reference interval of 71-180

Apparently my school insurance will cover the cost of an endocrinologist, so I have to make an appointment. There is a note on the lab report that says "hyperthyroidism: further evaluation needed."

My concern is that they'll give me a medication that will make me gain weight, which is obviously the opposite reason of why I'm here.

And, is it really possible to be hyperthyroid and be chronically obese?? I always thought that it would make you naturally thin. My mom has Hashimoto's which happened after a spell of hyperthyroidism that killed her thyroid. She lost so much weight during that hyper period, and she was already a small woman to begin with. Why can't I have that kind of luck??
