Hyperthyroidism is short for hyperthyroidism, and the typical symptoms of hyperthyroid hypokalemic periodic paralysis are recurrent episodes of symmetrical flaccid paralysis of the limbs, with paralysis of the lower limbs being more common. The attacks can last from a few hours to a few days and can be relieved by potassium supplementation. Severe hyperkalemia may cause paralysis of the respiratory muscles, resulting in dyspnea. Hyperthyroid hyperkalemic periodic paralysis occurs in young men between 20 and 40 years of age. Common triggers are excessive exercise, cold, intake of large amounts of sugary foods, alcoholism, and insulin use. Patients with hyperthyroid hyperkalemic periodic paralysis are advised to follow the doctor’s instructions to standardize the use of medication, so as to avoid delaying the condition and causing serious consequences.
