and bowel obstructions. In general, the benefits of gastric bypass outweigh the
risks for people with BMI > 40, and for people with BMI 35-40 In the
presence of medical problems associated with obesity.
Gastric Bypass Surgery for obesity is a medium-risk abdominal operation similar in danger to a
hysterectomy, cholecystectomy or bowel resection. The mortality risk for
appendectomy or hernia repair is on the order of one death in 700 operations.
With certain other operations such as those done for abdominal aortic aneurysms
or certain cancers, the risk of death following surgery may be as high as one
in 10. The mortality risk from surgery for obesity is one in 200. There is also
about one chance in 15 of developing some complication from surgery not
resulting in death. LAP-BANDÂ® Surgery is considered ten times safer
than Gastric Bypass Surgery.
