Quality of Life and Body Mass Index Changes Three Years After Laparoscopic Sleeve Gastrectomy in Taif City, Saudi Arabia

Background Obesity has become a major global health challenge, and its prevalence has tripled in the last four decades. Impaired quality of life (QoL) is a strong incentive for severely obese patients to seek help. Sleeve gastrectomy (SG) is the most frequently practiced bariatric procedure worldwide. This study aimed to investigate the QoL and changes in body weight three years post laparoscopic SG. Methods A cross-sectional, observational study was performed in outpatient clinics in Taif city, Saudi Arabia. The study included 147 adult patients who underwent SG at least three years before inclusion in the study. Data were collected using a questionnaire designed based on the validated Bariatric quality of life (BQL) and Gastroesophageal Reflux Disease Health-Related Quality of Life (GERD-HRQoL) surveys. Results All patients were suffering from class I, class II, or class III obesity before undergoing SG. Three years post-surgery, 72.8% reached their normal weight or were overweight (P<0.001). The mean± SD BMI (45± 7.0 kg/m²) significantly decreased to 26.8± 4.6 kg/m² (P<0.001). Most of the participants (78.2%) achieved an excess weight loss percent (EWL%) of 75% or more. The mean± SD BQL score was 45.5± 5.2 points and the median (IQR) GERD-HRQoL score was 7 (15). Higher EWL% was significantly associated with a higher BQL score (P=0.041). Conclusions The current study revealed a better quality of life among patients experiencing higher rates of excess weight loss percent (EWL%) after three years of sleeve gastrectomy as compared to other patients.
