Obesity is a chronic disease that seriously affects physical and psychological health. However, its management is insufficiently coordinated. The lack of defined therapeutic strategies is particularly evident since the arrival of new drug treatments. Coordination between the professionals involved- obesity specialists, general practitioners and other caregivers - and the involvement of the patient are all issues at the heart of an evaluation necessary for the construction of a personalized care project. Interdisciplinary centers must guarantee access to information and offer the full range of therapies currently available. An early psychological evaluation allows for the orientation of care, taking into account the vulnerability and resources of patients.
