Fact 2. The Crucial Role of Thyroid Hormones in Determining Energy Levels
Thyroid hormones act as the body’s “gas pedal,” controlling the speed at which body functions are carried out. These hormones influence almost every organ system, including heart rate, body temperature, and the nervous system. All of these systems collectively contribute to energy levels.
When thyroid cancer interferes with the production of these hormones, it can lead to an overall slowdown (hypothyroidism) or acceleration (hyperthyroidism) of bodily functions. In both scenarios, the patient can experience fatigue.
In hypothyroidism, because the body’s functions slow down, individuals often feel sluggish, tired, and lack energy. On the other hand, hyperthyroidism leads to an overactive system, resulting in feelings of exhaustion due to the body’s overexertion. (2)
