Obesity is a multifactorial pathology in which external (lifestyle, environment) and internal (psychological or biological, especially genetic) factors are involved. These are responsible for a positive energy balance. One of the external factors that can intervene in the genesis of obesity is the existence of eating disorders: bulimic hyperphagia. Some teams consider bulimic hyperphagia as a form of addiction. After bariatric surgery, the appearance of new addictions has been observed.

In connection with Pr Perney's addictology department, the investigators have observed that some patients under treatment for obesity at the endocrinology department subsequently developed other addictions, in particular misuse of alcohol.

The hypotheses of this research are :

There appears to be a transfer from eating disorders to substance misuse addiction in post-treatment of obesity, particularly in patients who have undergone bariatric surgery.

The misuse of addictive substances most concerned by this transfer of addiction in the post-treatment of obesity, particularly after bariatric surgery, seems to be the misuse of alcohol.

This will be the first French cohort study on addictive behaviors in patients undergoing bariatric surgery and the first international study including non-operated obese patients benefiting from medical care alone. This study will improve the multidisciplinary management of these patients by integrating addictologists.
