Though death occurs about 1 out of every 350 surgeries, the risk increases as the patients health worsens (diseases and excess weight are noted). Having the surgery at an older age also increases overall risks, because of co-morbidity problems. Two other serious risks, while rare, include heart attack and stroke.
