Weight Loss Outcomes
Weight Loss Outcomes Reported in Published MagDI Studies
Published studies of MagDI and Sleeve Plus report weight-loss outcomes using standard bariatric metrics such as percent total weight loss (%TWL) and percent excess weight loss (%EWL). This page summarizes the kinds of outcomes reported in the literature while noting the current limitations of follow-up duration and sample size.

What the published literature reports
- First-in-human and multi-center publications report meaningful weight loss following sleeve gastrectomy combined with MagDI (Sleeve Plus MagDI) at short- and mid-term follow-up.
- Revisional series report additional weight loss in patients who had previously plateaued or regained weight after a prior sleeve gastrectomy.
- Exact percentages vary by study, follow-up duration, patient population, and baseline BMI; readers should consult the original publications for study-specific values.
Important caveats
- Results vary among individuals. No bariatric procedure guarantees a specific weight-loss outcome.
- Current published data primarily reflect short- and mid-term follow-up. Long-term durability beyond currently published windows is still being studied.
- Adherence to nutritional, behavioral, and follow-up recommendations meaningfully affects long-term outcomes.
- Comparisons to established procedures (sleeve gastrectomy, Roux-en-Y gastric bypass) require head-to-head trials, which remain limited.
