Weight Loss After Bariatric Surgery in Different Age Groups

Area of Science:

• Bariatric surgery outcomes
• Metabolic changes with age

Background:

• Weight loss after bariatric surgery may be reduced in older patients due to metabolic changes.
• Existing research on age-related weight loss differences is conflicting.

Purpose of the Study:

• To determine if age impacts weight loss and comorbidity remission after bariatric surgery.
• To provide age-stratified data for patient counseling on expected surgical outcomes.

Main Methods:

• Retrospective analysis of 500 patients undergoing Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy.
• Patients stratified into five age groups: <30, 30-39, 40-49, 50-59, and ≥60 years.
• Mean follow-up of 3.6 years, assessing percent excessive body mass index loss (%EBMIL) and comorbidity remission.

Main Results:

• Younger patients achieved significantly higher %EBMIL at nadir and last follow-up compared to older patients.
• Weight loss was 86.6% in <30 years vs. 76.4% in ≥60 years at nadir.
• Younger age groups showed significantly higher rates of comorbidity remission.

Conclusions:

• Bariatric operations result in superior weight loss and comorbidity remission in younger patients.
• Bariatric surgery remains an effective option for weight management and improving health in older individuals.
