People who are underweight have a higher risk of dying post-surgery compared to overweight patients: Study
CHICAGO (REUTERS) - People who are underweight have a 40 per cent higher risk of dying in the first month after surgery than patients who are overweight, according to new research released on Monday. The findings suggest that body mass index, or BMI, may be useful in predicting which patients are at the greatest risk while recovering from surgery, United States researchers reported in the Archives of Surgery. Prior studies looking at the role of BMI in surgery have been mixed, said George Stukenborg of the University of Virginia in Charlottesville, who worked on the study. 'Patients with low BMI are at higher risk of death 30 days after surgery,' Mr Stukenborg said in a telephone interview.
