Severe obesity is associated with higher prevalence of psychiatric disorders and poor self-esteem. The aim of this study was to evaluate the impact of laparoscopic sleeve gastrectomy on self-esteem and depression in patients with obesity.
Methods:
This study is a randomized clinical trial. The statistical population included all patients with obesity (BMI ≥ 35) who were candidates for bariatric surgery in the hospital in 2019. Sixty of them were selected and randomly assigned to experiment (n = 30) and control (n = 30) groups. Rosenberg Self-Esteem scale and Beck Depression Inventory II were used to collect the data. The experimental group underwent bariatric surgery, and 12 months after surgery, data were analyzed using paired samples t-test and independent samples t-test. A p value <0.05 was considered significant.
Results:
The result showed that there was a significant difference between the pre- and post-test of the experimental groups at the p value levels of p < 0.020 for self-esteem and p < 0.0001 for depression; the difference between the post-test in the experimental and control groups in self-esteem (p < 0.003, t = 2.076) and depression (p < 0.0001, t = 5.290) was significant.
Conclusion:
The findings showed that significant weight loss after laparoscopic sleeve gastrectomy led to enhanced self-esteem and reduced depression; therefore, bariatric surgery is recommended for severe people with obesity to improve their mental health.
