  • What is a Specialized Center for Obesity?

    Obesity, a common chronic disease

    The problem of obesity currently affects almost the entire planet. According to the WHO , as many as 35% of adults worldwide are obese or overweight. Finally, 1.4 billion people aged 20 and over worldwide are affected. It should be noted that obesity is currently the 5th risk factor for death in the world and causes more than 2.8 million victims each year.

    Indeed, a chronic, multifactorial, progressive disease ranging from simple obesity to severe and/or complex obesity, it is a major risk factor for the most frequent pathologies (cardiovascular diseases, type 2 diabetes, etc. .) . The psychological and social consequences, such as low self-esteem, depression, stigmatization, are substantial and deleterious.

    In 2020, nearly one in two French people (47.3%) is overweight and/or obese. Today 17% of French people are obese. The proportion of people progressing to severe obesity is increasing (Obépi-Roche 2020) .

    The call for projects conducted by the Regional Health Agencies following the instruction of July 29, 2011 relating to the implementation of the National Health Nutrition Plan 3 and the obesity plan has made it possible to identify 37 centers specializing in taking in charge of severe obesity, centers present in mainland France and overseas.

    Normandy one of the most affected regions

    The stakes are high, particularly in Normandy.
    More and more Normans are suffering from obesity. According to the latest OBEPI survey (2020), Normandy is the 3rd French region most affected by obesity with 19.8% of adults experiencing obesity, compared to 17% for the national average.
    Pediatric obesity is also a problem. 2 reference centers in Normandy
    The Normandy region, particularly affected by obesity, has been allocated 2 Specialized Obesity Centers: Caen Normandie University Hospital and Rouen Normandie University Hospital. Each has the expertise and adapted equipment required to accommodate the most complex people with adult or pediatric obesity, in both medicine and surgery.

    Missions of CSOs : 3rd level of appeal

    In order to make the care offer accessible and understandable for patients with obesity, these specialized centers are entrusted with two missions carried out within the framework of national specifications. They intervene in 3rd level regional appeal:

    • 1st mission _ : ensure multidisciplinary management of severe and/or complex obesity
      Relying on :

      • specific skills: medical teams (nutritionists, endocrinologists, paediatricians, psychiatrists, etc.) , paramedical (dieticians, adapted physical activity professionals, psychologists, nurses, etc.) and surgical teams (team of surgeons and anesthetists-resuscitators specializing in surgery bariatric) .
      • and an adapted technical platform.
    • 2nd mission : organize the “obesity” care sector in the territory
      This is done in a process of animation and coordination of the multidisciplinary actors involved in the management of the disease, whether they are health establishments, liberals , medico-social and associations in conjunction with the networks and attending physicians and under the aegis of the ARS .
      This work requires creating a dynamic and formalizing partnerships by implementing actions that are not directly related to the care of a patient but which aim to organize the offer and disseminate information. skills (raising awareness, information, training, dissemination of best practice recommendations, etc. ).

    In addition, Obesity centers are engaged in research . In this context, the CSO of CHU Caen Normandie can rely on:

    • the Clinical Research and Innovation Department
    • on the so-called “integrated” Center (CIO) of the CHRU of Lille
    • FORCE network (French Obesity Research Center of Excellence) which is a network of excellence in clinical research on obesity and associated pathologies.
  • Our support

    overweight in adults

    The measurement tool commonly used to diagnose obesity is the body mass index ( BMI ).

    For overweight in adults ( BMI between 25.0 and 29.9 kg/m²) , there is no indication for hospital treatment. The management of overweight is carried out by the attending physician. International recommendations emphasize the need to stabilize weight, through regular physical activity and a balanced diet (see the website ). Physical activity is the most important element.

    adult obesity
    • If your BMI is between 30 and 35 kg/m² : you must first discuss this with your doctor. He can refer you to liberal professionals in his network: a nutritionist or dietician, a specialist or a structure offering adapted physical activity and, if necessary, to a psychiatrist or psychologist.


    • If your BMI is greater than 35 kg/m²:

    The 1st contact is made through a telephone interview with the secretary of the CSO . Depending on the data of this exchange, care at the CHU may be offered to you.

    You will then begin your care with a check-up hospitalization within the CSO of the CHU Caen Normandie. As part of the week hospitalization you will be accompanied by a multidisciplinary team for comprehensive and personalized care . Indeed, you will benefit from an individual medical and paramedical assessment (nurse, psychologist, dietician and adapted physical activity), as well as group workshops.

    The objective of the stay is to screen for diseases linked to obesity and to assess your individual situation. You will then be offered a care plan adapted to your needs in conjunction with your attending physician. This can be consultations at the CHU (medical, paramedical) and/or care via the PLANETH Patient therapeutic education platform and/or care in a follow-up and rehabilitation care establishment ( SSR : stay reimbursed in partly by social security and partly by your mutual insurance company) or with liberal professionals with dietary, psychological and physical activity support.

    If you have a request for surgical management of your obesity

    This treatment is reserved for the most severe forms of obesity, in the event of failure of well-conducted medical treatment.

    The recommendations of the Haute Autorité de Santé authorize adult patients meeting a set of strict conditions ( BMI ≥40 kg/m2 or BMI ≥ 35 kg/m2 with complications likely to be improved after surgery).

    Information brochure for patients considering bariatric surgery

    This brochure includes explanations of:

    • the conditions for benefiting from obesity surgery;
    • the different surgical techniques (gastric bypass (bypass); longitudinal gastrectomy (sleeve)…)
    • the organization of care, from the first interview with the doctor to follow-up after the operation;
    • the precautions to be taken to ensure the best chance of success.

    Pre and post-operative follow-up :

    As part of bariatric surgery, you will benefit from medical and paramedical follow-up not only pre-operatively but also post-operatively, in accordance with the recommendations of the High Authority for Health.

    Note that you may be offered a RAAC . The CHU Caen Normandie has also obtained the GRACE (Francophone Group for Improved Rehabilitation after Surgery) for obesity surgery. This quality label is the reward for multidisciplinary teamwork whose objective is to accompany the patient before, during and after his hospitalization, in order to help him recover his functional capacities more quickly after his surgery. obesity, and this, in complete safety.

    Patients' association : In addition, if you wish, you can meet the members of a patients' association who are on duty in the surgery department and who can accompany you throughout your journey.

    Reconstructive surgery : Finally, plastic and functional surgery may be offered to you.

    Childhood obesity

    The probability that a child in a situation of obesity will remain so in adulthood varies according to studies from 20 to 50% before puberty, and from 50 to 70% after puberty.

    It is recommended to monitor the body mass index systematically in all children and adolescents:

    • regardless of their age;
    • regardless of their apparent corpulence;
    • whatever the reason for the consultation;
    • at least 2 or 3 times a year.

    Some warning signs to look out for:

    • Early adiposity rebound (the earlier it is, the higher the risk of becoming obese) .
    • Continuous rise in the BMI since birth.
    • Rapid change of corridor of the BMI upwards.

    If the waist circumference / height ratio is > 0.5, the child has excess abdominal fat associated with increased cardiovascular and metabolic risk.

    The goal of care is to improve quality of life and prevent complications in adulthood.

    Regular and prolonged follow-up of at least 2 years is recommended.

    It is recommended that support:

    • is based on the principles of therapeutic patient education;
    • take into account diet, physical activity and sedentary lifestyle, the balance of lifestyles, psychological and socio-economic aspects;
    • involves the parents and/or responsible adults of the child or adolescent;
    • Obtain the support of the child or adolescent and his family, taking care not to make people feel guilty, hurt or stigmatize.

    3 levels of support:

    • 1st resort : uncomplicated overweight. Local care by the usual doctor.
    • 2nd recourse : complicated overweight or simple obesity. Multidisciplinary care organized on a territorial scale, calling on specialized professionals.
    • 3 rd resort: obesity + severe comorbidities / disability. Support organized on a regional scale and coordinated by a specialist doctor and team.

    Areas of support:

    Always in contact with the attending physician, whether pediatrician or general practitioner:

    • dietetic
    • physical activity
    • psychological
    • therapeutic stays in SSR according to varied modalities (day hospitals, more or less long stays)
    • bariatric surgery in certain very limited indications and only in specialized centers

    The Pediatrics Department of CHU Caen Normandie

    Medical and paramedical consultations

    • Multidisciplinary consultations bringing together pediatrician, dietitian +/- psychologist
    • Common transition consultations: pediatrician and adult nutritionist within pediatrics in order to optimize the adult relay
    • HDJ with complete assessment of obesity and its complications with proposal of a care plan adapted to the needs of the child/family in conjunction with the attending physician. This can be a follow-up by the CHU team and/or via the NPO Network (Normandy Pediatric Obesity) and/or in a pediatric follow-up and rehabilitation center ( SSR ) specialized in nutrition or with liberal professionals with taking in dietary, psychological and physical activity support.
