Polyuria and Acute Hyperglycemia Secondary to New-Onset Diabetes in a Young Woman With Friedreich's Ataxia.

A 23-year-old woman with progressive Friedreich's ataxia (FRDA) presented to a local urgent care facility for urinary urgency and frequency. A urinalysis showed the presence of trace ketones and glucose, and point-of-care testing revealed severely elevated glucose. The patient was referred to the emergency department and was admitted for further evaluation of hyperglycemia. Laboratory tests were negative for a urinary tract infection; however, results revealed elevated serum glucose and hemoglobin A1C. She was diagnosed with new-onset diabetes mellitus and started on insulin therapy. Management of her diabetes was complicated due to advanced neurodegenerative symptoms related to FRDA. An individualized treatment plan and coordination of care with her home facility were essential for managing her diabetes.
