Prevalence and Impact of Thyroid Disease. More than 12 percent of the U.S. population will develop a thyroid condition during their lifetime. 1  An estimated 20 million Americans have some form of thyroid disease. 2  Up to 60 percent of those with thyroid disease are unaware of their condition. Hyperthyroidism, another form of thyroid disease, is a condition causing the gland to produce too much thyroid hormone. 2  Symptoms include irritability, nervousness, muscle weakness, unexplained weight loss, sleep disturbances, vision problems and eye irritation.
In classic low thyroid both numbers drop. However, if thyroid hormone is still signaling cells to go, but cells lack nutrients to properly make energy, then a person may make 50 percent energy and 50 percent heat. If the problem worsens a person could make 35 percent energy and 65 percent heat.
