Fractures - Calcium, Vit D, Nutrition Probs

Your Path

  • Fractures - Calcium, Vit D, Nutrition Probs


  • Low calcium intake
  • Low vitamin D levels, from breakdowns along the pathway: low nutritional intake and/or lack of sun, dark skin color (decreased D2 and D3); decreased production D-25 OH (liver); decreased production D 1, 25-OH (chronic kidney disease)
  • Socio-economic factors affecting access to adequate/appropriate food
  • Weight loss surgery (gastric by-pass, sleeve gastrectomy, other)--> impaired absorption
  • Chronic infection leading to overall poor nutrition: HIV, TB, other
  • Idiopathic hypercalcuria
  • Other disorders leading to chronic malabsorption

Risk Factors

  • Dark skin
  • Poor nutrition
  • Chronic kidney disease
  • Impaired absorbtion


  • May have pain and/or dysfunction at site of fracture
  • Fracture may occur at early age and/or with less than expected force
  • May have radiographic evidence osteoporosis/osteomalacia in absence of symptoms
