A healthy thyroid is crucial to whole body health. In fact, the thyroid is often referred to as ‘the body’s major metabolic regulator’ as this organ keeps your body humming.

Many individuals struggle with an an under active thyroid with low thyroid problems becoming more widely accepted. But reverse T3 dominance is often overlooked. Reverse T3 dominance, sometimes referred to as Wilson's Syndrome is a very common thyroid condition.

Thyroid Hormone Levels

The thyroid produces two main hormones: thyroxine (T4) and triiodothyronine (T3). When your thyroid is working well it produces adequate amounts of T4 along with smaller amounts of T3. T3 is the more potent thyroid hormone, it fires up your metabolism. Under normal conditions T4 will convert to both T3 and reverse T3, with the body quickly eliminating reverse T3.

Reverse T3 dominance occurs when too much T4 is converted to reverse T3, the inactive form of T3. Reverse T3 circulates and blocks the action of T3 leading to the wide range of symptoms associated with hypothyroidism (low thyroid function).

Get a Real Medical Diagnosis

Reverse T3 dominance can be difficult to diagnose as it is not generally accepted as a low thyroid problem by medical doctors. In addition, the standard thyroid tests of TSH, T4 and T3 can appear to be within normal reference ranges.

Only a special test that specifically measures reverse T3 can rule out reverse T3 dominance. If your doctor only wants to test TSH, or you are told your thyroid is normal after only checking TSH, you need to find a doctor who will do a thorough assessment of your thyroid hormones.

It is vital to determine if your thyroid is manufacturing T4, and that the T4 is converting through to active T3 and not reverse T3. To get a real medical diagnosis you need to assess TSH, free thyroxine (T4), free triiodothyronine (T3) and reverse T3.

Treatment for Reverse T3 Dominance

Treatment of reverse T3 dominance treatment requires a holistic approach that includes getting plenty of rest, reducing as much emotional stress as possible, performing moderate exercise, eliminating negative lifestyle habits and avoiding thyroid damaging foods.
