Sorry, I just got your message about H (I'm in Piecing, btw).
Hair loss is definitely a symptom of hypothyroidism.
As for the odor question - well, I've never read about it being mentioned in relation to thyroid disease. Still - i will relate a rather embarrassing personal fact - which may or may not have anything to do with my thyroid. (I'm post-radioiodine ablation of my thyroid for Graves disease, now hypothyroid on hormone replacement). I still have problems with nightsweats (unclear whether it is menopausal - but I'm on BCPs - or thyroid related - altho my numbers are normal). One thing I have noticed, though - when I sweat during the day, like during a workout, it is normal. When I sweat in my sleep, though - PHEW! STINKY! I have no idea why the difference.
That said - diabetes can also cause a change in body odor, and diabetes is more common in families with thyroid disease - so H should get checked for both. Also, some medications affect your body odor.
