Summary

This study follows 70 adults with severe obesity for three years after bariatric surgery, checking in before the operation and again at several points afterward. Researchers will measure psychological distress, perceived stress, and impulsivity, along with weight changes and the need for psychological support. The goal is to understand how weight-loss surgery affects mental health over time and whether patients might benefit from extra emotional care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
This study could clarify how bariatric surgery affects mental health over time, potentially guiding psychological support for patients before and after weight-loss surgery.
What could go wrong
As an observational study, it cannot prove cause and effect. The small size and long follow-up may limit how broadly the findings apply.
