Roux-en-Y gastric bypass shows better long-term outcomes than sleeve gastrectomy
Last updated July 18, 2026
Key finding
Mean HADS anxiety score for SG decreased by 1.59 units over 10-years (p = 0.027).
This study compared long-term outcomes of laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass in patients with type 2 diabetes and obesity, revealing significant differences in anxiety and physical health scores.

Plain-language summary
What this paper says
A plain-language read of the study’s main message and where it applies.
Study focus
This study compared long-term outcomes of laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass in patients with type 2 diabetes and obesity, revealing significant differences in anxiety and physical health scores.
Clinical relevance
Understanding the long-term outcomes of these surgical interventions is crucial for clinicians and patients when considering weight loss surgery options. The findings suggest that while both procedures can reduce anxiety, Roux-en-Y gastric bypass may offer more significant benefits in physical health and overall well-being for patients with type 2 diabetes and obesity.
Keep in mind
Limited generalizability due to specific population characteristics. Potential unmeasured confounders affecting outcomes. Short follow-up duration may not capture all long-term effects.

Main Effects
SG group showed a decrease in HADS anxiety score by 1.59 units (p = 0.027).

Evidence Suggest
- Anxiety decreased by 1.59 units for SG patients (p = 0.027).
- SR-RYGB improved physical function by 19 points compared to SG's 12 points (p = 0.026).
- General health scores improved by 17 points for SR-RYGB versus 10 points for SG (p = 0.036).
Who this applies to
- Adults with type 2 diabetes and obesity considering weight loss surgery.
- Patients seeking long-term outcomes of bariatric procedures.
Keep in Mind
- Results may not apply to populations outside the study's demographics.
- Long-term follow-up is essential for comprehensive outcome assessment.
- Differences in emotional well-being need further exploration.
Between the Lines
- Limited generalizability due to specific population characteristics.
- Potential unmeasured confounders affecting outcomes.
- Short follow-up duration may not capture all long-term effects.
