Graves disease is the most common form of hyperthyroidism. Manifestations include weight loss, tremor, heart palpitations, sweating, and heat intolerance. This condition increases the metabolic rate and oxygen consumption, requiring an increased supply of oxygen and removal of metabolic products from the skeletal muscles.1 Hyperthyroidism may cause an over-reliance on muscle glycogen during exercise programs.2 Those who develop arthralgias secondary to this condition will greatly reduce their daily activities in order to control joint pains. Severe cases of hyperthyroidism may result in myopathy of the proximal and respiratory muscles. Treatment usually results in insufficient thyroid hormone production, requiring the client to take synthetic thyroid hormone.
