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 your level is too high, or too low, discuss treatment options with your doctor. If your TSH level falls between 3.5-4.5, but you have many of the symptoms of hypothyroidism, find an integrative medicine practitioner who will help you achieve a level within the desirable range.
