Hypokalemic periodic paralysis (HPP) due to hyperthyroidism is a rare clinical condition. It is more commonly seen among Asian males as compared to its global incidence. We are reporting a rare atypical case of HPP which presented in our Medicine outpatient department (OPD) with complaint of repeated episodes of weakness in all of the four limbs. However, at the time of presentation, the patient did not complain of any weakness but investigation profile revealed a low potassium level which was done during the previous episode. On the basis of all routine and specific investigations including EMG-NCV, muscle biopsy and thyroid profile as well as clinical examination, the patient was diagnosed as a case of hyperthyroidism and was managed with oral anti thyroid medication. Considering the diagnostic difficulties in such patients especially when such patients present with atypical clinical presentation, it is important to rule out hyperthyroidism specifically in patients presenting with acute onset of weakness in all the four limbs.
