What is Thyrotoxic Myopathy?
Thyrotoxic myopathy is a neuromuscular disorder that may accompany hyperthyroidism (Graves' disease, caused by overproduction
of the thyroid hormone thyroxine). Symptoms may include muscle weakness, wasting of the pelvic girdle and shoulder muscles,
fatigue, and heat intolerance. Muscle breakdown may occur in acute cases. Physical acts such as climbing stairs may be difficult.
Patients may develop muscle damage to the eyes and eyelids, which may affect mobility of the eye muscles, and temporary, but
severe, attacks of muscle weakness known as periodic paralysis.
