- If your TSH level is increased, it usually indicates that you have hypothyroidism. Hashimoto's thyroiditis is the most common cause of primary hypothyroidism.
- If your TSH level is decreased, it usually indicates hyperthyroidism. Graves' disease, multinodular goiter, and toxic nodules are some of the common causes of hyperthyroidism.
Note: TSH normal range levels show circadian variation (fluctuates during the 24-hour cycle), reaching peak levels between 2-4 a.m. and at a low between 6-10 p.m.
