CHRONIC FATIGUE SYNDROME AND HIGH(ER) REVERSE T3 HORMONE by Dr. John Crisler
ANOTHER reason it is important to see a physician well-practiced in Interventional Endocrinology.
We know what to do with high(er) Reverse T3 levels. And it would not matter whether the patient presents with Chronic Fatigue Syndrome (CFS) or any other medical issue which is causing them to feel tired, worn down, and hurt: a good and proper thyroid hormone evaluation (which includes a rT3 test) will many times point us in the right direction.
The article is also remarkable in that even though these patients are suffering what is clearly hypothyroidism—as defined as the SYMPTOMS of low thyroid—they may have completely “normal range” TSH. That means even the possibility of it being a thyroid problem will be completely dismissed by most doctors, for most doctors allow the mere taking of a TSH as sufficient for evaluating thyroid hormone function. Nothing could be further from the truth, to the great detriment of the patient.
As far as “normal range” goes, it’s important to know it is determined by purely statistical means…not health and/or happiness. There are vast differences as we go across what is supposed to be “low normal” and upwards. So you definitely do not have to even be outside “normal range’ to be quite sick; and very responsive to proper hormonal optimization. It can be as night and day.
For a little background, Thyroid Stimulating Hormone (TSH) can stimulate the thyroid gland to make mostly a form of thyroid hormone called T4. But T4 is just a prohormone, and must be converted into its active form, T3, out in the body, in order for the thyroid hormone to get into the cells, and do its good work. MANY things hinder this conversion: stress, fatigue (adding to the fatigue), many prescribed medications, severe dieting/starvation, and all manner of nutritional deficiencies. Then the T4 is instead converted into what is called Reverse T3, which not only plunders available T4, it also directly blocks the good T3 that has been made from working. Double whammy….resulting in a vicious cycle of hormonal XXX that can sink the patient, and their life, lower and lower.
All the above, over time, can also result in Adrenal Insufficiency. Now add in the fact it takes cortisol to get the T3 into the cells. Finding the right doctor just became even more critical.
In my experience, as well as others in my field, proper treatment of high(er) Reverse T3 brings great relief for CFS sufferers. And almost everyone else with such hormonal imbalances.
