Background: Several previous studies have suggested a correlation between weight loss and age after bariatric surgery.
Objective: The aim of our study is to further address age as a preoperative factor to determine the amount of weight loss after bariatric surgery.
Materials and Methods: We performed a retrospective analysis of outcomes of a prospectively maintained database of 1,244 obese patients who underwent either sleeve gastrectomy (SG) or Roux-en-Y gastric bypass surgery (RYGB) at our hospital between 2011 and 2015. We analyzed the 3-month, 6-month, and 1-year postoperative percent total body weight loss (%TBWL) of obese patients who underwent bariatric surgery based on their preoperative age.
Results: The average age of patients included in the study was 45 years old with a range of 21–78 years. An inverse relationship between preoperative age and postoperative weight loss was observed. Younger patients achieved a higher %TBWL than older patients at the 3-month, 6-month, and 1-year postoperative follow-up. The average %TBWL for all patients at the 3-month, 6-month, and 1-year postoperative follow-up periods were 15.5%, 23.6%, and 28.9%, respectively. At the 1-year follow-up, for every decade increase in age (above the average age of 45), patients lost 4% less TBWL.
Conclusion: In our study, younger patients tend to lose a greater amount of %TBWL than older patients after bariatric surgery.
