Changes in clinical depression following Sleeve Gastrectomy

INTRODUCTION: Bariatric surgery is safe and efficient surgical method for weight loss, but it is not free from complications. We aim to evaluate the prevalence of depression after Sleeve Gastrectomy (SG) in a narrow period of time on Iranian ethnicity. METHODS: 307 cases that underwent SG in Erfan Niayesh hospital were included. The questionnaire was based on International Classification of Diseases, Ninth Revision (ICD‐9) codes to define diagnoses. Screening follow‐up period was 20 to 24 months. The level of statistical significance was set at p < .05. RESULTS: Of 307 subjects, preoperative depression was 30.2% and post‐operative depression was 37.7% (p = .025). Besides, BMI, dyslipidaemia, good feelings about body size and weight loss were statistically significant at p < .05.There was an increased risk of depression following the procedure mainly in divorced cases. CONCLUSION: The prevalence of clinical depression after sleeve gastrectomy was statistically significant and dependent on other variables. We provided guidance for people considering SG and their clinicians in terms of evaluating potential risks and benefits of surgery.
