Review Articles

  • * Bariatric surgical procedures can be subdivided into restrictive, malabsorptive, and restrictive and malabsorptive categories.
  • * The greatest amount of excess weight loss occurs by 18 to 24 months following these procedures and can exceed 70% in certain procedures.
  • * Postoperative malabsorption of fat-soluble vitamins and protein is most common in patients with combined restrictive and malabsorptive procedures such as biliopancreatic diversion.
  • * Patients undergoing a bariatric surgical procedure are at an increased risk of fracture due to changes in bone metabolism, with the potential risk for decreased fracture-healing that has not been extensively studied.
  • * Regardless of the improvement in body mass index, patients undergoing a bariatric surgical procedure appear to remain at higher risk for complications with total joint arthroplasty when compared with the general population.
