Andi,

Do you mean the lab value for thyroid stimulating hormone is low, or the level of it in your body is low?

I have what is called "sub-clinical" hypothyroidism, where the lab value of the thyroid stimulating hormone is high because my body is not properly processing the fact that my T3 and T4 are normal range, and thinks the level in the body is low. The thyroid stimulating hormone keeps screaming at the thyroid to produce more T3, hence, the value is high. If your lab value is low but T3 and T4 are normal, maybe the reverse, if there is such a thing as sub-clinical hyperthyroidism.

Best of luck to you,

Hopeful
