The Association Between Appetite and Quality of Life in Adults with Obesity or Severe Obesity Post-Sleeve Gastrectomy Procedure: A Cross-Sectional Study.

BACKGROUND

Sleeve gastrectomy (SG) is considered as the most common bariatric procedure in Saudi Arabia. It is a non-reversible procedure defined as removal of a large portion of the stomach.

OBJECTIVE

The objective of the current study is to compare the appetite and quality of life (QoL) between adults' post-sleeve gastrectomy and obese/morbidly obese adults (pre-SG).

METHODS

A cross-sectional study design was conducted in adults (aged between 18 and 65 years), post-sleeve gastrectomy (n = 80, 41 Males and 39 Females) and obese group (n = 60, 28 Males and 32 Females). The study population was recruited from the bariatric surgery clinic of King Abdullah Bin Abdul-Aziz University Hospital. A self-reported questionnaire was collected that included a visual analogue scale (VAS) to assess the appetite level, and SF-36 QoL questionnaire.

RESULTS

No significant differences were found in age and gender between the study groups (p > 0.05). The median score feeling of fullness was significantly higher in the SG group (77.5, IQR: 48 and 50, IQR: 40, respectively) than in the obese group (p < 0.001). The amount of food eaten was statistically lower in the SG group (30, IQR: 20) than the obese group (50, IQR: 60) (p = 0.005). Patients post SG had significantly higher QoL scores in all physical and mental scales, physical component summary and mental component summary (p < 0.003).

CONCLUSION

Patients post SG have improved appetite and QoL. Satiety, less prospective food consumption, BMI, age, gender and comorbidities are associated with QoL. Future studies are needed to compare the QoL in post-SG patients with the normative values of the QoL in Saudi Arabia.
