A 28-year-old woman presented to our emergency department (ED) with acute, painless left wrist and hand weakness and numbness after twenty-two months of a diet consisting solely of one cup of ramen noodles per day. Initial laboratory results revealed potassium 2.2 mmol/L, lactic acid 5.0 mmol/L, PCO2 66.8 mmHg and bicarbonate 40 mmol/L. She was admitted to our inpatient service for further imaging, blood testing, electrolyte repletion, vitamin supplementation, and cardiac monitoring. She was subsequently discharged with symptomatic improvement. We review various etiologies of myeloneuropathy related to poor nutritional intake, including the effects of hypokalemia from a potassium-poor diet.
