What this trial studies

This observational study investigates the complex risk factors that contribute to weight regain after various obesity treatments, including bariatric surgery and anti-obesity medications. It utilizes a range of questionnaires to assess demographic information, dietary habits, quality of life, psychological status, and food addiction among participants. The goal is to identify the underlying reasons for weight loss failure, which can inform future interventions and support for patients struggling with obesity. Participants will be evaluated based on their responses to these assessments to better understand the multifaceted nature of weight management.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 20 to 65 with a BMI of 30 or higher who have previously attempted exercise or dietary control.

Not a fit: Patients who have undergone bariatric surgery or have severe psychiatric disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the factors influencing weight regain, leading to improved treatment strategies for obesity.

How similar studies have performed: While there have been studies exploring weight loss outcomes, this particular approach focusing on a comprehensive assessment of multiple risk factors is relatively novel.
