The Effect of Bariatric Surgery on the Mental State of Patients in Israel: A Systematic Review

Abstract

Purpose: The purpose of this systematic review is to investigate the impact of bariatric surgery on the mental state of patients in Israel. The study aims to address how bariatric surgery affects the mental state of patients and whether there is an association between the mental state post-surgery and weight loss.   Theoretical Reference: This review utilizes the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to systematically gather and analyze research evidence. The theoretical foundation is based on existing literature examining the relationship between bariatric surgery, mental health, and weight loss outcomes.   Method: The study employs a systematic review method, adhering to the PRISMA guidelines. Eligibility criteria included studies published in English or Hebrew in the last 10 years, focusing on the effects of bariatric surgery on the mental state of patients in Israel. A comprehensive search strategy was used to identify relevant articles from electronic databases, and data were extracted and summarized in a table format.   Results and Conclusion: A total of 10 studies were included in the final review. The results indicate that bariatric surgery generally improves the mental state of patients in Israel, both in the short term and long term. Key findings suggest improvements in depression, anxiety, and overall mental health post-surgery. However, there are contradictions regarding the timeline of these improvements and their association with weight loss. Some studies found no direct link between mental health improvements and weight loss, while others identified factors like emotional regulation and self-management as crucial for maintaining mental health post-surgery.   Implications of Research: The findings highlight the need for tailored mental health support for bariatric surgery patients, focusing on emotional regulation and self-management strategies. Healthcare providers should consider these factors when planning post-operative care to enhance the overall well-being of patients.   Originality/Value: This review fills a gap in the literature by specifically examining the mental health outcomes of bariatric surgery patients in Israel. It provides valuable insights for healthcare professionals and policymakers to improve the holistic care of patients undergoing bariatric surgery, emphasizing the importance of addressing psychological well-being alongside physical health outcomes.
