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. This thyroid hormone is 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, and although they are similar in structure 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.
Your body works hard to maintain a healthy balance of both T3, and RT3 to keep your metabolic rate in check. Problems arise when there’s a shift in this balance and too much RT3 is produced.
To clarify further, 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 your body pools RT3 this hormone attaches to the T3 receptor. As a consequence the RT3 blocks free T3 from doing its job.
Chronic illness, extreme dieting, and/or prolonged stress are the main reasons why the body makes an abnormal amount of RT3.
The Symptoms of High Reverse T3
High RT3 has a powerful effect on slowing your metabolism. For this reason, an abnormal amount of RT3 pushes your body into a hypothyroid state which triggers a long list of low thyroid symptoms.
Here is your high RT3 symptoms checklist:
+ You are constantly fatigued
+ You feel cold all the time
+ You have problems losing weight, or gain weight easily
+ You have low blood pressure and heart palpitations
+ You have mood swings that range from mild to severe
+ You feel down, even depressed
+ You have brain fog, and memory problems
+ You have swelling around your throat
+ You are easily irritated and get stressed out
+ Your muscles ache, or you have pains in your joints
+ You are experiencing menstrual problems, or irregular periods
+ You are sensitive to cold weather, or feel cold all the time
+ Your skin is dry and pale
+ You have sluggish digestion and constipation
+ Your hair is thin, or falls out excessively
+ Your face, hands and/or feet become swollen or puffy
+ You have lost your mojo!
What Is A Reverse T3 Test?
The reverse T3 (RT3) test measures the amount of RT3 in your blood. Unless you specifically test RT3 this common thyroid problem will get missed.
However 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.
