This 2016 systematic review analyzed studies on weight regain after sleeve gastrectomy (SG). It found that definitions of weight regain varied across studies, leading to inconsistent reporting. Reported rates of weight regain ranged from 5.7% at 2 years to 75.6% at 6 years post-surgery. Proposed causes included initial sleeve size,
This retrospective nested case-control study analyzed data from 12,676 bariatric surgery patients in Quebec (2001–2014), matched with 38,028 obese and 126,760 non-obese controls. Over a mean follow-up of 4.4 years, bariatric patients exhibited a higher postoperative fracture risk compared to obese (RR 1.38; 95% CI: 1.23–1.55) and non-obese controls (RR
This large-scale retrospective cohort study analyzed data from 65,093 adults (aged 20–79 years, BMI ≥35 kg/m²) who underwent Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), or adjustable gastric banding (AGB) between 2005 and 2015 across 41 U.S. health systems. RYGB resulted in the greatest total weight loss at 1, 3,
This prospective observational study assessed the incidence and predictors of hair loss in 42 morbidly obese female patients undergoing laparoscopic sleeve gastrectomy (LSG). Over a 12-month postoperative period, 41% of patients reported hair loss. While mean serum zinc and iron levels remained within normal ranges, low levels of these micronutrients
