title: Osteoporosis after total gastrectomy. Results of a prospective, clinical study.
abstract: BACKGROUND
  Osteopenia and enhanced risk of fractures have been reported after partial gastrectomy, but the significance of total gastrectomy is still unknown.
  
  
  METHODS
  Twenty-six patients were followed up for at least 3 years after total gastrectomy. The intake and S-levels of vitamin D, phosphate, magnesium, and calcium were prospectively studied, and a whole-body dual-energy X-ray absorptiometry scan was performed at a mean of 5 years after gastrectomy.
  
  
  RESULTS
  At this time point we found normal blood levels of vitamin D, calcium, and phosphate. Food intakes of phosphate, calcium, magnesium, and vitamin D reached the recommended daily allowances. Bone mineral density was similar to that of a control population, and increasing values were seen concomitant with an increase in body weight with the time after gastrectomy.
  
  
  CONCLUSIONS
  Calcium homeostasis and bone mineral densities seem not to be affected by total gastrectomy, at least when studied over a period of 5 years, an observation that hypothetically can be explained by weight recovery with time after the operation.
