On a regular basis, a physician would come across a number of patients presenting with muscular weakness of different severities. Among the causes of the muscular weakness, hypokalemia remains as one of the important causes. This condition is called Hypokalemic Periodic Paralysis. It is a neurological manifestation of hypokalemia and it is completely reversible with appropriate management. Hence, identifying the cause of hypokalemia in each individual at the time of presentation is very important to make a diagnosis, treat accordingly and prevent the further episodes. In this article, three cases of hypokalemic periodic paralysis are presented with typical muscular weakness caused by hypokalemia which in turn is due to different causes and are recovered by giving potassium correction.
