I was reading on a web site about "Wilson's Syndrome", which apparently is diagnosed by hypometabolism (temperature below 98.2) together with high reverse T3. The site describes the condition as: "The thyroid gland makes T3 and T4. T3 is the active thyroid hormone and every cell in the body has molecular docking stations for T3. T4 is made by the thyroid, circulates and eventually ends up in the liver where it is converted to T3 and a tiny amount of a substance called Reverse T3 (RT3). RT3 has no action on the cell, except that it binds with the receptor sites, the tiny docking stations, and blocks the action of T3. However, in the normal situation, T3 dominates and RT3 is no problem. However, when a person experiences prolonged stress, the adrenal glands respond by manufacturing a large amount of cortisol. Cortisol inhibits the conversion of T4 to T3 and favors the conversion of T4 to RT3. If stress is prolonged, a condition called Reverse T3 Dominance occurs and persists even after the stress passes and cortisol levels fall. Apparently, RT3 itself acts like cortisol and blocks the conversion of T4 to T3. Reverse T3 Dominance is the cause of hypometabolism because too many receptor sites are blocked by RT3 and the chemical reactions of life slow down. These reactions give off heat and are the source of heat in the body. They make us warm blooded. When those reactions slow down, our temperature drops. This drop in temperature slows down enzymes in every cell of the body causing a condition of Multiple Enzyme Dysfunction which is the heart of hypometabolism." My question is what does it mean when you have normal thyroid levels, and high RT3, but do NOT have low temperature? In this case the body is able to run its function with the amount of thyroid receptors that RT3 has not blocked? You are effectively "normal" for thyroid purposes?
