title: SECONDARY HYPERPARATHYROIDISM AFTER BARIATRIC SURGERY: TREATMENT IS WITH CALCIUM CARBONATE OR CALCIUM CITRATE?
abstract: BACKGROUND
  Bariatric surgery, especially Roux-en-Y gastric bypass, can cause serious nutritional complications arising from poor absorption of essential nutrients. Secondary hyperparathyroidism is one such complications that leads to increased parathyroid hormone levels due to a decrease in calcium and vitamin D, which may compromise bone health.
  
  
  OBJECTIVE
  To compare calcium carbonate and calcium citrate in the treatment of secondary hyperparathyroidism.
  
  
  METHODS
  Patients were selected on the basis of their abnormal biochemical test and treatment was randomly done with citrate or calcium carbonate.
  
  
  RESULTS
  After 60 days of supplementation, biochemical tests were repeated, showing improvement in both groups.
  
  
  CONCLUSIONS
  Supplementation with calcium (citrate or carbonate) and vitamin D is recommended after surgery for prevention of secondary hyperparathyroidism.
