Brief Summary

Normalizing weight gain and preventing the redistribution of body fat is a major health issue, and could help prevent the onset of various symptoms of metabolic syndrome. Above all, it is important to understand the mechanisms by which these different treatments affect adipose tissue. To this end, the investigators will first study the impact of GLP-1 analogues on adipose tissue. The main objective is to show that subjects treated with a GLP-1 agonist have a significant change in their oxytocin levels compared with subjects not treated with a GLP-1 agonist.

Outcome Measures

Primary Outcomes (1)

  • Rate of oxytocin

    show that subjects treated with a GLP-1 agonist have a significant change in oxytocin levels compared with subjects not treated with a GLP-1 agonist.

    one time (before surgery)

Secondary Outcomes (1)

  • Fibrosis rate

    At surgery

Study Arms (2)

whole blood in a GLP1

OTHER

Oxytocyne assay in a GLP1 analogue or non-analogue patient population

Other: Blood GLP1

whole blood in non analague patient population

OTHER

Oxytocyne assay in a GLP1 analogue or non-analogue patient population

Other: Blood No treated GLP1

Interventions

On the day of surgery, the surgeon will remove visceral adipose tissue (1 cm3) from the operative waste. The adipose tissue is separated into 2 samples, one frozen in nitrogen, the other embedded in formalin. The samples are then sent to the Institut de Biologie de Valrose (iBV) to assess any differences between the two groups of patients (patients treated with anti-GLP-1 analogues
