Results Initially, investigators identified 23,263 patients at least 21 years of age with at least 1 RYGB or AGB procedure code on a date after 1 year of continuous enrollment in the health plan.After applying the eligibility criteria, investigators identified 12,482 patients who had undergone an RYGB procedure and 8922 patients who had undergone an AGB procedure.The incidence of any nonvertebral osteoporotic fractures was the primary outcome of interest.Secondary analyses assessed the risk of fracture at these individual sites: humerus, wrist, hip, and pelvis.Vertebral fracture was not included as an outcome due to the difficulty in capturing incident vertebral fracture using claims data.Potential confounders (including age, year of surgery, geographical region, osteoporosis diagnosis, receipt of osteoporosis medications, history of fall, BMD testing, and markers of healthcare use intensity) were assessed with type of bariatric surgery during the baseline period of 365 days and on the index date.Patients in the RYGB group had an increased rate of nonvertebral fractures compared with those in the AGB group (hazard ratio [HR], 1.43; 95% CI, 1.13-1.81).In site-specific analyses, patients who underwent an RYGB procedure had a higher risk of fracture at the hip and wrist compared with those who underwent an AGB procedure (HR, 1.54 and 1.45, respectively).
Among patients with severe obesity, bariatric surgery is effective at reducing body weight; however, there are potential clinical risks associated with these procedures, such as metabolic bone disease.The claims data provided patient demographic information and longitudinal data on inpatient and outpatient medical claims, procedure claims, and pharmacy claims.Patients with morbid obesity who were at least 21 years of age and had undergone RYGB or AGB were identified for potential inclusion in the study cohort.Doctors often use the body mass index (BMI) and health conditions such as type 2 diabetes (diabetes that started in adulthood) and high blood pressure to determine which people are most likely to benefit from weight-loss surgery.Gastric bypass surgery is not a quick fix for obesity. After this surgery, you must eat healthy foods, control portion sizes of what you eat, and exercise.

RYGB is a true metabolic surgery that is composed of both gastric reduction and intestinal reconstruction, resulting in greater metabolic improvements compared with surgeries that involve restriction, such as AGB.
