Recurrent, refractory hypokalemia as a diagnostic clue to thyrotoxic periodic paralysis in a patient with acute kidney injury and suspected Guillain‐Barre syndrome

Abstract

Abstract When clinical presentation is atypical, especially in a non‐Asian population, the finding of recurrent and refractory hypokalemia can serve as a key diagnostic clue for timely diagnoses and management of thyrotoxic periodic paralysis. In suspected cases, complete thyroid laboratory panel should be measured so that T3 toxicosis is not missed.
