Predicting Weight Loss After Pharmacological or Surgical Treatment in Patients With Obesity
Research of Predictive Factors of Weight Loss After Pharmacological or Surgical Treatment in Patients Suffering From Obesity
Source: ClinicalTrials.gov · Last updated 14 May 2026
Brief summary (registry, in English)
As with other nutritional strategies, the clinical response to bariatric surgery can be highly variable, with weight regain being a frequent occurrence. Recent evidence on anti-obesity medication indicate similar inter-individual variability in clinical response. Among multiples factors, co-occurrence of eating disorders such as binge eating disorder has been implicated in insufficient clinical response. Improving our ability to predict how patients will respond to obesity treatment is necessary in order to tailor the care pathways we offer. The mechanisms involved in disturbances of eating behaviour before and after surgery remain largely unknown. This study aims to identify the predictive factors of weight loss after pharmacological or surgical treatment, as well as the cognitive and biological mechanisms that mediate this effect.
