A 56-year-old woman with type 2 diabetes mellitus and hypertension presented with acute left-sided weakness and altered mental status, for which she was hospitalized. The patient, who was obese, was in her usual state of well-being until 2 months before this presentation, when she noted a gradual onset of generalized weakness. She received a diagnosis of severe hypokalemia that was refractory to oral potassium supplementation. The outpatient workup of the cause of her hypokalemia was in progress.
