Can hyperthyroidism Cause High reverse T3?
In common forms of hyperthyroidism serum levels of triiodothyronin (T3) are higher than those of thyroxin (T4) and isolated elevations of serum T3 have even been noted. We report 9 cases of proven hyperthyroidism with normal or low levels of T3 and elevated T4 and reverse T3 (rT3).
What does reverse T3 reveal?
Description. The Reverse T3 (RT3) test measures the inactive form of the hormone T3 or Triiodothyronine. Triiodothyronine is one of two major hormones produced by the thyroid (the other is T4, or thyroxine). Under normal conditions, the body converts T4 to T3 and RT3 in specific ratios.

If you have hyperthyroidism, you may experience a fast heartbeat, increased appetite, anxiety, sensitivity to heat, or sudden weight loss.
Is reverse T3 an active hormone?
Reverse T3 (rT3) is a metabolically inactive form of thyroid hormone, which is generated from T4 via the type 3 5′-deiodinase enzyme. In addition to producing rT3, the type 3 5′-deiodinase enzyme is also responsible for decomposing rT3 into inactive diiodothyronine.
Does Reverse T3 cause weight gain?
The balance of T3 and rT3 is based on your body’s energy needs. With less-than-optimal T4, hypothyroidism is usually characterized by low T3 and low rT3. Yet, sometimes, unexpectedly high rT3 can develop if you are hypothyroid. This can cause weight gain, and it may also be caused by weight gain.
Why is testing reverse T3 important?
Reverse T3 (rT3) This is often ordered in conjunction with a T4 test because it’s a hormone produced from your T4’s metabolism. If you’re experiencing chronic stress, depression, brain fog, anxiety, weight fluctuations or hair loss, your doctor may recommend this test for you.
