This drop in TSH is an attempt to return circulating thyroid hormone levels to normal. So, a test to measure the amount of TSH in your system will usually show lower than normal TSH when the thyroid is overactive. So, in general, LOWER TSH = OVERACTIVE THYROID / HYPERTHYROIDISM.
If the pituitary sees very little T4, then it produces more TSH to tell the thyroid gland to produce more T4. Once the T4 in the blood stream goes above a certain level, the pituitaryâs production of TSH is shut off.
