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.
Certain populations are more likely to develop high TSH levels. Pregnant women with a past history of thyroid problems or dietary iodine deficiency tend to develop TSH problems. High TSH levels during pregnancy can increase health complications of an unborn baby and normal health issues in the mother.
