Up until the late 1940’s, hypothyroidism was successfully diagnosed and treated based primarily on a number of common symptoms and oftentimes on your Basal Metabolic Rate (BMR). Your BMR is entirely dependent upon your thyroid function. Doctors would determine your BMR by measuring your body’s oxygen consumption, which would indicate your body’s rate of metabolism. An inefficient use of oxygen was clearly a sign of hypothyroidism. Another one of the common symptoms oftentimes used to diagnose hypothyroidism was cholesterol levels. Research studies at that time, and still today, showed that your cholesterol levels were directly correlated to your thyroid function. When thyroid function is low, cholesterol levels rise. When the thyroid is stimulated to normal levels, cholesterol levels fall to within normal range. And so doctors began using elevated cholesterol levels as another indicator of hypothyroidism. The relationship between thyroid and cholesterol is easily explained through a basic understanding of the human body. Your body requires cholesterol, thyroid hormone, and vitamin A in order produce the hormone pregnenolone. Pregnenolone is a very important hormone because it is the precursor to all of the highly protective steroid hormones including two very important ones, DHEA and progesterone. When you are hypothyroid and lack thyroid hormone, then your body can’t convert cholesterol as it normally would. Thus, your cholesterol builds up as a protective mechanism in attempt to stimulate the production of more protective hormones. At that time, the diagnosis was conclusive based on therapeutic trials. You would be treated for hypothyroidism while your measureable indicators (BMR, temperatures, cholesterol, etc.) were charted over time. If your symptoms improved as your indicators normalized, then the diagnosis was confirmed and treatment would continue. Based on these well accepted methods that were used at the time, hypothyroidism was commonly diagnosed and treated in 40-45 percent of the population. 9
