Abstract

Thyrotoxic hypokalemic periodic paralysis is a rare disorder and is a clinical condition which manifest as thyrotoxicosis, hypokalemia and recurrent episodes of muscle weakness. Hyperthyroidism is often due to Graves Disease. Episodes are occurring in the form of sudden onset of muscle weakness and deterioration of consciousness, and patients are completely healthy between the episodes. A case admitted with sudden onset of muscle weakness who diagnosed with hyperthyroidism due to Graves Disease was described and an improvement in muscle weakness was achieved with replacement of potassium; moreover, beta-adregenic receptor blocker and anti-thyroid treatment was started for preventing paralysis episodes. We aimed to report our case with thyrotoxic hypokalemic periodic paralyses -a rare disorder- in the light of briefly review of literature.
