A
disease of the thyroid
gland (underactive) that effects mostly
females:
symptoms include
slow metabolism,
dry skin,
sleepiness, dry hair. It can be
hereditary. It may be caused by your body attacking your
thyroid (
Hashimoto disease), or it may be
inexplicable.
I finally went to the doctor and was diagnosed with it after a semester of truly excessive naps & other strange sleepiness. They subscribed synthroid, but as i didn't notice any changes after a couple of months (and I resented having to take drugs to be "normal"), I haven't taken it since.
I am now used to being sleepy. I hide it well.
