Known risks
Risks reported in the current MagDI and broader bariatric surgery literature include, but are not limited to:
- Bleeding
- Infection
- Bowel obstruction
- Anastomotic stricture (narrowing of the connection)
- Nutritional deficiencies
- Need for reoperation or additional procedures
- Failure to achieve expected weight loss or metabolic improvement
- Standard risks associated with anesthesia and abdominal surgery
Current unknowns
- Long-term outcomes beyond the follow-up periods currently published.
- Long-term rate and timing of revision or additional intervention.
- Individual variability in weight-loss and diabetes outcomes.
- Comparative long-term effectiveness versus established procedures such as sleeve gastrectomy or Roux-en-Y gastric bypass.
