Relation between weight loss and age after laparoscopic sleeve gastrectomy

Area of Science:

• Bariatric Surgery
• Obesity Management
• Metabolic Surgery

Background:

• Laparoscopic Sleeve Gastrectomy (LSG) is a popular bariatric procedure for obesity.
• Understanding factors influencing LSG outcomes is crucial for patient selection and expectation management.

Purpose of the Study:

• To investigate the influence of patient age on weight loss outcomes one year after LSG.
• To compare weight loss metrics between patients younger and older than 40 years.

Main Methods:

• A cohort of 55 obese patients undergoing LSG was retrospectively analyzed.
• Patients were stratified into two groups: under 40 years and over 40 years.
• Preoperative and one-year postoperative Body Mass Index (BMI), percent BMI Lost (% BMIL), and percent Excess BMI Lost (% EBMIL) were compared.

Main Results:

• Patients over 40 (Group 2) showed significantly lower one-year % BMIL (13.58% vs. 19.29%) and % EBMIL (56.75% vs. 82.95%) compared to those under 40 (Group 1).
• Postoperative BMI was higher in the over-40 group (36.15 kg/m² vs. 30.05 kg/m²).
• Patient demographics and preoperative BMI were similar between the age groups.

Conclusions:

• Age is a significant determinant of weight loss success following LSG.
• Patients aged over 40 should be counseled on potentially reduced weight loss efficacy after LSG.
• Further research may explore age-related physiological differences affecting bariatric surgery outcomes.
