what is subclinical hypothyroidism
Subclinical hypothyroidism is the third stage of the condition, while overt hypothyroidism is the 4th. When the TSH is between 2.5 and 10 mIU/L and T3 and T4 is within normal limits, this is known as subclinical hypothyroidism (at this point, people may or may not have thyroid antibodies). This means that your thyroid is still able to make enough thyroid hormone, but not without sacrifice.
