Vitamin D Deficiency and Related Disorders Differential Diagnoses

  • Author: Vin Tangpricha, MD, PhD; Chief Editor: Romesh Khardori, MD, PhD, FACP  more...
 
Updated: Oct 30, 2015
 
 

Diagnostic Considerations

Conditions to be considered in the differential diagnosis of vitamin D deficiency include the following:

  • Lack of dietary intake
  • Inadequate sunlight exposure
  • Malabsorptive diseases - Celiac sprue, short bowel syndrome, cystic fibrosis
  • Use of antiepileptic medications that accelerate vitamin D metabolism - Phenytoin, phenobarbital
  • End-stage liver disease
