I have had constant fatigue, weakness, cognitive impairment, low body temp, 20 pound
weight gain,
and what seems like an inability to lose
weight. These are all of course symptoms of hypothyroidism and it really seems like that is my answer. Particularly when you consider my mother was diagnosed with hypothyroidism in her early 30s and I have a cousin on my dad's side who had all the symptoms of hypothyroidism but normal levels of T3, T4, and TSH.
