**8. Conclusions**

Bariatric surgery has been demonstrated to be a valid solution for the treatment of obesity. It is recommended for well-motivated and informed patients with severe obesity or obesity with related comorbidities. Approximately, all bariatric surgery procedures are effective in producing weight loss and related substantial improvements in health conditions [26–28].

Candidates for bariatric surgery require not only a multidisciplinary preoperative screening, which is aimed to prepare and educate patients for the lifestyle changes required after surgery, but also would benefit from a supportive, integrated additional psychological interventions aimed to maximize weight loss and weight loss maintenance after surgery. Particularly, weight loss is not the primary goal of psychological interventions. In fact, findings indicate that the pre-operative interventions do not have a significant effect on weight loss [29]. Rather, they should be considered an option for patients to overcome their difficulties, reduce pre-existing symptomatology, and improving in their eating behaviors and lifestyle. On the contrary, psychological post-operative interventions have been associated with significant weight loss and currently they are the most promising approach to improve the outcomes of bariatric surgery.
