On this episode of Living Beyond 120, Mark and Dr. Gladden discuss thyroid function and disfunction. The thyroid is a hormone gland in the body that is under the control of the brain, determining the metabolic rate of a cell, through hormone production. One of those things this process does is help the mitochondria put out more ATP, which is “the currency of life.”  They discuss hypo- and hyperthyroidism, plus some other conditions, and some of the potentially far-reaching health consequences of when one’s thyroid doesn’t function properly. They consider some of the symptoms that people suffer when people have hypothyroidism, even if common medical tests do not recognize it. Dr. Gladden recommends what people can do to get a more accurate picture of their thyroid health.
