If your TSH is low you probably have hyperthyroidism (overactive thyroid), if it's high you probably have hypothyroidism (low thyroid function); however, other mechanisms may account for abnormal TSH levels (abnormal pituitary function). Testing your thyroid hormone levels (t3, t4) is more complete. ...Read more
