Solo biofragmentable magnetic duodenoileostomy (MagDI) creates a partial intestinal bypass that significantly reduces body weight and improves type 2 diabetes markers in patients with mild obesity (BMI 30-35).
This paper describes a new, minimally invasive surgical option for people with mild obesity (BMI 30-35) and type 2 diabetes. Instead of removing part of the stomach, doctors use magnets to connect the upper small intestine (duodenum) to the lower small intestine (ileum). This creates a partial bypass that helps you lose weight and control blood sugar without major surgery or permanent implants. The magnets dissolve and pass naturally after about 3 weeks. While promising, this is a new procedure with limited long-term data, so it should be considered carefully with a specialist.
Solo BMAS MagDI was effective in creating significant, clinically meaningful weight loss, although, as expected, to a lesser degree than first-generation LMAS MagDI with SG... The previous cohort of solo BMAS MagDI patients, all diagnosed with T2D, entered the study with a mean HbA1C of 8.2% and FPG of 187.9 mg/dL... Postoperatively, 2 patients (13.0%) stopped all T2D medications by 9 months; 7 patients (46.7%) reduced their T2D medications postoperatively.
Why this rating
First-in-human, single-center, small sample size (n=15), short follow-up (max 1 year), and lack of a control group.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
