You have hypothyroidism. The normal range of tsh levels is 0.4 to 4.0 milli-international units per liter. If you're already being treated for a thyroid disorder, the normal range is 0.5 to 3.0 milli-international units per liter. A value above the normal range usually indicates that the thyroid is under active. This indicates hypothyroidism. Standard treatment for hypothyroidism involves daily use of the synthetic thyroid hormone levothyroxine (levo-t, synthroid, others. Treatment with levothyroxine will likely be lifelong, but because the dosage you need may change, your doctor is likely to check your tsh level every year.
