Super Obesity Ups Risk of Dying After Weight-Loss Surgery
WEDNESDAY, Oct. 21 (HealthDay News) -- People who are super obese and those with the most chronic health problems face an increased risk for dying within a year after weight-loss surgery, a new U.S. study has found.
The research involved 856 men and women who had bariatric (weight-loss) surgery at 12 Veterans Affairs medical centers between 2000 and 2006. They averaged 54 years old and had an average body-mass index (BMI) of 48.7. BMI is a measurement based on height and weight, and a BMI of 40 or greater is considered class 3 or morbid obesity.
About 36 percent of the group was considered super obese, with a BMI of 50 or higher. In addition, 8 percent also had such chronic diseases as diabetes and heart disease.
During the follow-up, 54 people died, including 1.3 percent who died within 30 days of their surgery, 2.1 percent who died within 90 days of surgery and 3.4 percent who died within a year, the study found.
Those who were super obese and those with co-existing chronic diseases had the highest risk for early death. Super obese people accounted for 30 of the 54 deaths and had 30-day, 90-day and one-year death rates of 2 percent, 3.6 percent and 5.2 percent, respectively.
