RESUMEN

Diabetic ketoacidosis (DKA) is an extreme complication of diabetes mellitus characterized by hyperglycemia, metabolic acidosis, and ketonemia. Thyroid storm, a potentially life-threatening manifestation of thyrotoxicosis, presents with a multitude of symptoms, including hyperthermia, tachycardia, and altered mental status. Periodic paralysis can be precipitated by different metabolic disturbances, including thyrotoxicosis, and may lead to extreme episodes of muscle weakness and paralysis. We present a case of a 41-year-old female with a history of type 1 diabetes mellitus and hyperthyroidism, who presented with DKA complicated by an impending thyroid storm and likely periodic paralysis exacerbated due to hypokalemia. Prompt recognition and aggressive management of each component of this triad were essential for a positive patient outcome. This case highlights the importance of a broad and comprehensive approach to managing complex metabolic emergencies, particularly in patients with multiple comorbidities. Our patient presented to the emergency department with symptoms of severe vomiting, shortness of breath, and altered mental status. Laboratory investigations revealed metabolic derangements consistent with DKA, alongside impending thyrotoxicosis and hypokalemia-induced periodic paralysis. Management involved aggressive fluid resuscitation, insulin therapy, anti-thyroid medications, and potassium supplementation, with a multidisciplinary approach to stabilize the patient's condition.
