The thyroid sets the metabolism for the entire body. When it is functioning normally, the whole body is in synchrony and all parts are doing their job. Hypothyroidism, or low thyroid, is called, “The Great Imitator” because when low the thyroid can cause almost any metabolic disease in the human body!
Simple enough then, just check for low thyroid and correct it if it is abnormal? Part of the problem lies in what is “abnormal” and what thyroid labs to test. One needs at a very minimum 3 to 4 lab test to evaluate the thyroid but up to a dozen or more lab tests to start to be more complete! There is no test in medicine that always answers the questions asked!
The problem issue is usually apparent in the thyroid lab panel and appropriate action can be taken.
The thyroid and the adrenal glands are intimately tied together and Dr. DeCosmo calls the “the twins.” What happens in the thyroid effects the adrenals and vice versa but they are not equal. The adrenal gland is the stronger of the two and has more of an effect on the thyroid than the other way around. If the adrenals are off, it is near impossible to balance the thyroid!
