This article looks at the symptoms of high reverse T3. But before we get started let’s discuss the important relationship between triiodothyronine (T3), thyroxine (T4), and reverse T3.
You may already know that a healthy body naturally produces ample amounts of T4. In fact, this thyroid hormone is often termed a pro-hormone as it is converted to T3 as required.
T3 is the principal bio-active hormone. In effect, this thyroid hormone is your metabolic driver. It’s the reason adequate T3 makes a real difference to how you feel.
What Is Reverse Triiodothyronine (RT3)?
Reverse T3 (RT3) is an inactive form of T3. It’s important to know two facts about this thyroid hormone;
# RT3 has a similar structure to T3 so it can easily lock into the T3 cell receptor.
# Despite their similar structures RT3 has the opposite effects of T3. Now that’s not necessarily a bad thing. In fact, it’s normal for your body to produce a certain amount of RT3 to help balance your metabolic rate.
You see your body works hard to maintain a healthy balance of both T3, and RT3 to keep your metabolic rate in check. However, problems arise when there’s a shift in this balance and too much RT3 is produced. High RT3 has a powerful effect on slowing your metabolism which creates a hypothyroid state.
Over time RT3 pools in the body.
When RT3 is elevated it indicates there is less T4 converting to T3, and this T4 is instead being diverted towards production of RT3. When this occurs RT3 pools in the body. There is now more RT3 that can attach to the T3 receptor. And as a consequence T3 is blocked and can no longer attach and get on with doing it’s job.
The Symptoms of High Reverse T3
An abnormal amount of RT3 triggers a long list of hypothyroid symptoms. Signs you might have high RT3…
+ Constant fatigue
+ Sensitive to cold weather, or feel cold all the time
+ Difficulty losing weight, or gaining weight easily
+ Thinning hair, and noticeable hair loss
+ Low blood pressure, and heart palpitations
+ Mood swings that range from mild to severe
+ Depressed mood
+ Brain fog, and memory problems
+ Swelling around the throat, or hoarseness
+ Easily irritated, and feel stressed
+ Muscles aches, and joint pain
+ For women, menstrual problems, or irregular periods
+ Skin is dry, and pale
+ Sluggish digestion, and constipation
+ Face, hands and feet are swollen and puffy
+ You have lost your mojo!
What Is A Reverse T3 Test?
To properly test for reverse T3 (RT3) it’s essential the specific RT3 test is performed. If not, this common thyroid problem is easily missed.
The RT3 test measures the amount of RT3 circulating in your blood.
Unfortunately testing RT3 remains controversial. For that matter, you may even find some medical practitioners will not authorize this test. This is despite the fact the RT3 blood test is essential to properly diagnosis, and manage a thyroid hormone imbalance.
