The onset of TM requires toxic levels of the thyroxine hormone due to overproduction by the thyroid gland. Documented cases have only been diagnosed in conjunction with patients with hyperthyroidism. While hyperthyroidism is more common in women, the development of TM was more common among men with hyperthyroidism. Case studies of patients with diagnosed hyperthyroidism showed that only about half of them complained of symptoms characteristic of TM. Further examination as described above indicated that about 75% of the studied patients showed signs of muscle fiber degeneration. This indicates that either at the time of study some patients were in early stages of TM or the symptoms were insignificant patients.
