Thyrotoxic Periodic Paralysis With Severe Hypokalemia Precipitated by Acute Alcohol Intoxication in a Patient With Graves' Disease.

We present a case of a 29-year-old male who presented with thyrotoxic periodic paralysis (TPP) precipitated by acute alcohol intoxication. TPP is an endocrine emergency that presents with an episode of acute flaccid paralysis with hypokalemia in the setting of thyrotoxicosis. Individuals who present with TPP are thought to have an underlying genetic predisposition. Overactivation of the Na+/K+ ATPase channel leads to large-scale intracellular shifts in potassium, leading to low serum levels and the clinical manifestations of TPP. Severe hypokalemia can lead to life-threatening complications such as ventricular arrhythmias and respiratory failure. Therefore, timely recognition and management are essential in cases of TPP. In addition, understanding the precipitating factors is necessary for adequate counseling of these patients to prevent further episodes.
