Hypothyroid Symptoms with Normal Thyroid Counts. Could it be REVERSE T3?

by in Health Tips, Uncategorized January 5, 2019

Thyroid issues are very common in Australia today, with many factors affecting the function of this very important gland. You may have all the symptoms of hypothyroid disease, but annoyingly, all of your regular thyroid pathology has come back normal.

Commonly when standard tests are performed for thyroid function they will include TSH (thyroid stimulating hormone), T3 and T4 levels and sometimes thyroid antibody tests. Unfortunately, it is uncommon in mainstream medicine to test for something called reverse T3

Thyroid hormone T4 must be converted into T3 for the body to actively use it. T4 is essentially inactive whilst T3 is active. T3 is the the hormone that drives our metabolism and basically all body functions.  Some refer to T3 as ‘the magic hormone. But in every story there must be a villain right?

 

Sometimes during the  conversion of T4 to T3, something goes awry, and this can be due to a multitude of reasons. For this  conversion to take place, an enzyme called 5-deiodinase is necessary. When something goes wrong in this conversion, too much reverse T3 may be produced causing an imbalance known as reverse T3 dominance. The problem with too much reverse T3 is that it is virtually inactive in the body. To add to this problem, reverse T3 will attach to the T3 receptor therefore blocking the critical function of T3 in the body.

Reverse T3 dominance will therefore cause hypothyroid symptoms but general pathology will come back as normal. It is worth having a chat to a practitioner if you suffer the symptoms of hypothyroid but have normal labs. Supplementing with some thyroid hormones can exacerbate reverse T3 dominance, so it is crucial to get to, and work on, the cause of the problem.
