A member asked:

When pituitary gland is responsible for thyroid .then effect on tsh goes to high or low side of normal range means hypo or hyperthyroid condition?

A doctor has provided 1 answer

If your: Pituitary is responsible for hypothyroidism, by definition your TSH will be low. That's what causes the thyroid deficiency. If it is normal, and your free T4 is normal, you do not have hypothyroidism or are on replacement, possibly unnecessarily. Check w/your doctor or see an endocrinologist.
