  8. How do you manage Osteomalacia?
A
  1. Refers to bone softening due defective bone mineralisation. Rickets is the form in children before closure of growth plates
  2. Vitamin D is synthesized in the skin from cholesterol with the help of UV radiation
  3. Malabsorption diseases i.e. IBD, CKD whereby the kidneys fail to active Vitamin D to absorb Ca2+ and PO43-
  4. Vitamin D helps absorb Calcium and Phosphate from intestines and kidneys into blood, to facilitate bone mineralisation.
  5. Hypocalcemia will cause Type 2 hyperparathyroidism, stimulating osteoclast activity to increase serum calcium levels
  6. Below 25 = Vit D deficiency, 25-50 = Vit D insufficiency, above 75 = Optical
  7. Ca2+ (low), PO43- (low), PTH (high), ALP (high), XR (osteopenia), DEXA (low BMD)
