Bariatric Surgery Survival – 5 Countries, 500,000 Participants

A recent population-based cohort study (JH Kauppila et al. Gastroenterol 2019; 157: 19-27) examined the effects of bariatric surgery on survival from Nordic countries between 1980-2012.

Among 505,258 obese individuals, 49,977 had bariatric surgery.

Key findings:

  • Overall mortality rates were lower in the surgery group during the first 14 years but higher after 15 years (HR 1.20 with CI 1.02-1.42).  Thus, overall, obese patients who underwent bariatric surgery had longer survival times than obese patients who did not have surgery.  Both groups had higher mortality than the general population
  • The improved survival compared to those without surgery was related to decreased mortality from cardiovascular mortality, diabetes and cancer.  However mortality due to suicide was increased.
  • Limitations: lack of detailed data including BMI, smoking and alcohol consumption
