With an increase in the instances of obesity, the cases of type 2 diabetes, which is caused by obesity, have also increased significantly. Because of this, the number of obesity metabolic operations performed on diabetes patients with obesity is also accumulating, and there has been no concern for implementing approaches to psychological support for these patients. Negative psychologies include anxiety, depression, passive attitude, stress, fear and impulse control disorder, which continuously influence the patient in a vicious circle of recurrence of obesity and diabetes, even after the obesity metabolic operation was attempted. Therefore, for the success of the obesity metabolic operation and the continuation of self-management of obesity and diabetes post-operation, psychological support is very important. Post-operative psychological support approaches include a respiration method, autogenic training, self-expression training, a stress reduction program, thought-change training and communication skills.
