We read an article written by Canetti et al.1 with interest. The authors assessed mental health and psychological outcome in patients who underwent bariatric surgery compared with those who did not have bariatric surgery. The authors found that, after 10 years of follow-up, those who had surgery had worse general metal health, sense of control and fear of intimacy. Physical composite of quality of life in these patients was better. However, this study includes only seventy participants. Also, the authors did not report other composites of quality of life including social, functional or total quality of life.

In a meta-analysis by Lindekilde et al.,2 the authors assessed the impact of bariatric surgery on quality of life in 9433 participants from 72 studies. They found that bariatric surgery had a significant positive influence on overall quality of life. They also found that bariatric surgery had a greater benefit on physical composite of quality of life than mental, social and functional quality of life. This result suggests that bariatric surgery is more likely an intervention towards physical composite of quality of life. There may be an area of improvement in psychosocial, functional status and postsurgical support.

Although benefits of bariatric surgery is well-established, findings from the article by Lindekilde et al. and the above meta-analysis suggested that healthcare practitioners should focus on quality of life improvement in all areas in patients with bariatric surgery. Further studies should be carried out to investigate intervention that improves quality of life in these patients.
