Background: Laparoscopic sleeve gastrectomy (LSG) is a restrictive type bariatric surgery that promotes significant, sustainable weight loss in obese individuals (body mass index (BMI) ≥ 40 kg/m² or BMI 35.0-39.9 kg/m² with major comorbidity) resulting in 45-60% excess weight loss (%EWL). Unrealistic expectations have been consistently reported in the literature of individuals seeking both non-surgical and surgical weight loss interventions. It has been argued that they may negatively impact treatment adherence and weight loss outcomes. -- Purpose: To examine the postoperative weight loss and body shape expectations of LSG candidates in Newfoundland and Labrador (NL). -- Methods: The 'Goals and Relative Weights Questionnaire' and 'Stunkard Figure Rating Scale' were administered to 84 consecutive LSG candidates. They reported postoperative weight loss and body shape expectations in four categories: (1) dream (whatever you wanted); (2) happy (would be happy to achieve); (3) acceptable (could accept even if not happy with); and (4) disappointed (would not view as successful in any way) before the start of a bariatric surgery education session. Body image dissatisfaction (BID) was scored. -- Results: Of the 84 candidates, 69 were women and 15 were men (age 43.7 ± 8.7 years; BMI 49.0 ± 7.0 kg/m²). Expectations for their dream (71.1 ± 11.7 kg), happy (80.0 ± 14.2 kg), acceptable (86.2 ± 17.0 kg) and disappointed (105.6 ± 21.0 kg) weights equated to higher %EWLs (88.7 ± 11 .3 %EWL; 76.4 ± 12.8% EWL; 68.2 ± 16.1 %EWL; and 40.6 ± 21.0 %EWL) than are clinically expected from LSG. %EWLs were significantly different (p<0.05-p<0.003) between all weight loss categories, except goal and dream weights. Men and women were dissatisfied with their current body image (BID score= 4.1± 1.3) and had unrealistic postoperative body shape expectations. -- Conclusions: There is a disconnect between the weight loss expectations of bariatric surgery candidates in NL and what can be clinically expected from LSG surgery.
