Periodic Thyrotoxic Hypokalemic Paralysis (PTHP) is a rare endocrinological complication characterized by hypokalemia, episodes of muscle weakness and thyrotoxic symptoms. The following is a case report of PHHP in a black patient diagnosed with hyperthyroidism during an episode of sudden and progressive weakness associated with hypokalemia. PHHP is often underdiagnosed and should be remembered as a diagnosis of acute muscle weakness in young patients, especially males, regardless of ethnicity, although it is frequent in Asians.
