A 42-year-old man developed a myopathy in the setting of malnutrition following Roux-en-Y gastric bypass for the treatment of morbid obesity. No specific vitamin or electrolyte deficiency was identified. Muscle biopsy revealed type II fiber atrophy. He recovered after the initiation of continuous enteral feeding. We suggest that malnutrition was the underlying cause of his myopathy.
