What this trial studies

This is a prospective observational study of adults with morbid obesity who are candidates for bariatric surgery. Participants will be followed before surgery and at 1 month, 1 year, 2 years, and 3 years to track weight changes, psychological symptoms, stress indicators, and hair cortisol. The goal is to describe how mental health and related factors change after surgery and to identify needs for psychological support during follow-up. Data will include sociodemographic, clinical, nutritional, and lifestyle variables alongside validated psychological measures. No specific intervention is being tested beyond the standard surgical care and longitudinal assessment.

Why it matters

Potential benefit: If successful, the study could help identify when patients may need psychological support after bariatric surgery to improve long-term outcomes.

How similar studies have gone: Similar observational work has explored psychological changes after bariatric procedures, supporting feasibility and value of this approach.
