[Thyrotoxic periodic paralysis]

Abstract

Thyrotoxic periodic paralysis (TPP) is a rare complication of hyperthyroidism mainly seen in patients of Oriental origin and is rarely encountered in Western countries. TPP clinically resembles familial periodic paralysis with recurrent episodes of weakness or flaccid paralysis of especially the legs. Transient hypokalaemia is regularly observed during attacks and remission can be achieved by administration of potassium salts. The definitive treatment of TPP is to restore euthyroidism. This case describes a thyrotoxic patient who initially presented with periodic paralysis.
