Off-topic, but my husband had hyperthyroidism caused by Graves Disease. He lost about 50 pounds in short order when I was pregnant in 1999, he lost some muscle function, and he lost a lot of hair. We had no idea what was wrong with him - my MIL insisted it was stress from being sole financial support of our family, I was worried it was something terminal, but my mother suggested he have his thyroid tested. Sure enough, that was it.
I lost about half my hair, total, through bursts of hair loss that accompanied every major change in thyroid levels. It's all growing back, but I have this "halo" of different regrowth lengths, so no matter what I do I look
awful!I was having these dizzy spells that came with garbled speech and loss of motor function that we couldn't diagnose for months. My biggest fear was stroke (I was 43, and Dad was only 48 with his first stroke) but we quickly ruled that out. When a dizzy spell hit while driving to the doctor, though, we finally realized my pulse was racing over 180bpm because my thyroid was running so high. Lucky I didn't pass out at 70mph!
Unfortunately, the 20 pounds I lost in the short time as hyper came back quickly after the RAI treatment. Now I get to lose it all over again, and then some (a lot, really!).
I will never make it to a size tew, though!
