Introduction: One of the current criteria for bariatric surgery is to be of an age between 18 and 65 years. In all the available literature, there is a lack of studies focusing on the results of bariatric surgery in younger patient. This could be of great interest because the weight loss response can be altered by differences in metabolism or compliance rate. In recent years, a high amount of patients between 18 and 25 years of age have undergone bariatric surgery in our center, and it is our aim to evaluate the weight loss results in this youngest patient group.
Methods: All preoperative and perioperative data from patients aged 18-25 and 35-55 years (control group) were collected retrospectively. Bariatric procedures took place between 2011 and 2014. Follow-up data were gathered prospectively by collecting (laboratory) measurements and questionnaires.
Results: In total, 103 young adults (mean age 22.5) were matched to 103 adult control patients (mean age 42.6) on BMI and date of surgery. Of the young adults' group, 75 patients underwent a Roux-en-Y gastric bypass (RYGB) compared with 80 patients in the control group. Three years after RYGB, mean %total body weight loss (%TBWL) was 34 (± 9) and 30.3 (± 9) (p = 0.03), respectively.
Conclusion: Bariatric surgery is effective in young adults, and results after RYGB are even better compared with age groups in which bariatric surgery is most often performed. The high remission rate of comorbidities shows the importance of effective treatment options at a young age and preventing damaging effects in the long term.
