Background
- AKA: Hypovitaminosis D
- Vitamin D
- Lipid soluble
- Acts as a hormone to:
- Stimulate intestinal calcium absorption
- Maintain adequate phosphate levels for bone development
- Regulate cell growth proliferation and apoptosis
- Modulate the immune system
- Deficiency leads to impaired bone mineralization and disease such as:
- Rickets in children
- Osteomalacia and Osteoporosis in adults
Etiology
- Inadequate intake
- Inadequate sunlight exposure
- Disorders limiting vitamin D absorption
- Conditions preventing vitamin D conversion into active metabolites (i.e. Renal Failure)
