Reverse T3

[Diana58]

Hi

I’m from the USA

I will be getting my test results after being on NP for 3 months

My question is

If everything looks great blood wise

And I feel great

But my reverse T3 is extremely high

How can I lower it without changing my numbers on the other (TSH Free T3 and Free T4)

Don't worry about reverse T3. There are many reasons for high rT3 and only one of them is to do with the thyroid.

When it's thyroid related it's due to a build up of T4. As you are taking NDT then it's very unlikely you have excess T4 and it will be due to a non-thyroidal cause.

Conditions that contribute to increased Reverse T3 levels include: Chronic fatigue, Acute illness and injury, Chronic disease, Increased cortisol (stress), Low cortisol (adrenal fatigue), Low iron, Lyme disease, Chronic inflammation. Also selenium deficiency, excess physical, mental and environmental stresses. Also Beta-blocker long-term use such as propranolol, metoprolol, etc. Physical injury is a common cause of increased RT3, also illnesses like the flu. Starvation/severe calorie restriction is known to raise RT3. Diabetes when poorly treated is known to increase RT3. Lyme disease. Cirrhosis of the liver. Fatty liver disease. Any other liver stress Renal Failure. A fever of unknown cause. Detoxing of high heavy metals.
