Objective:

To investigate the association between chronotype and biochemical and anthropometric parameters in patients undergoing bariatric surgery, and to assess the impact of chronotype on surgical outcomes at 6 and 12 months post-intervention, highlighting its significance for personalized treatment strategies.

Key Findings:
  • Chronotype may influence dietary habits and weight loss outcomes post-bariatric surgery, with evening chronotype individuals showing a statistically significant poorer weight loss outcome compared to morning types.
  • Bariatric surgery may potentially modify a patient's chronotype profile, suggesting a bidirectional relationship.
Interpretation:

The study suggests that chronotype could be an important factor in predicting bariatric surgery outcomes, highlighting the need for chronotype-adjusted interventions to enhance patient care.

Limitations:
  • Limited existing literature on the impact of chronotype on bariatric surgery outcomes, with potential biases in patient selection.
  • The study's findings may not be generalizable beyond the single-center context.
Conclusion:

Further research is needed to clarify the relationship between chronotype and bariatric surgery outcomes, and to explore potential chronotype-adjusted treatment strategies, particularly in diverse populations.
