Non-diabetic Euglycemic Ketoacidosis in an Adult Patient With Spinal Muscular Atrophy Type II

Spinal muscular atrophy (SMA) is a rare neuromuscular disease that develops as a result of the degeneration of the anterior horn cells in the spinal cord and lower brainstem motor nuclei, resulting in progressive muscle weakness and atrophy. While the initial presentation of this disease involves diffuse muscular atrophy at an early age, patients with an established diagnosis and later-stage disease often present with gastrointestinal symptoms related to metabolic imbalances. Here, we examine the case of an adult patient with SMA type II who presented with complaints of 12 hours of intractable nausea and vomiting. The patient was found to be in euglycemic ketoacidosis (EKA), an uncommon, but not unheard of, metabolic derangement in SMA patients with severely decreased muscle mass.
