Good news from the doctor today. My wife, Holly, was found to have low TSH levels in her last checkup, so they did some more tests. Low TSH levels generally indicate hyperthyroidism, a condition in which one is gaunt, nervous, with their body's clock running too fast. My wife is none of those things, so we were a bit concerned about other possibilities, and problems with her pituitary gland. After a battery of bloodtests and scans last week, we found out today that she just has subclinical hyperthyroidism. Basically, her thyroid is outputting normal amounts of the T3 and T4 hormones, though her pituitary isn't sending it the right signals to do so. Nothing really wrong with her, no symptoms, and so there's nothing to fix, they just monitor the levels, in case the body's clock speeds up later and full-blown hyperthyroidism takes hold.
I made the same diagnosis while reading through the various pamphlets as we waited for the doctor to appear, I wonder if I can send her HMO a bill? :)
