I second the recommendation to have another opinion on the thyroid number. I've dealt with hyper and hypothyroidism over the past few years, and even when my blood comes back in the defined normal range, its often not working for me.

As SallyShortyPnts said, these numbers are most commonly used to treat older women, not young athletic types (32 yr old male here). Low on the normal scale is way too low for me, and could be way too low for your daughter.

Only problem is that it can be hard to find a doctor that knows how to treat atypical thyroid patients. I've had my best luck seeing a naturalpath.
