Advanced bariatric surgery for the treatment of obesity in Madrid
SADI-S (Single Anastomosis Duodeno-Ileal Bypass with Sleeve) bariatric surgery has established itself as one of the most effective and long-lasting techniques for the treatment of severe obesity and type 2 diabetes. At Clínica 3 de Mayo, Dr. Jesús Lago, a specialist in metabolic and obesity surgery, performs this advanced intervention with a personalized, safe approach focused on the patient’s long-term well-being.
SADI-S is a modern evolution of the classic duodenal bypass or duodenal switch, with a simplified technique that reduces risks and improves nutritional absorption.
It consists of two main steps:
Thanks to this combination, the patient eats less and absorbs less, achieving a more profound and lasting weight loss than with other techniques.
Dr. Jesús Lago has extensive experience in mixed techniques (restrictive and malabsorptive), which guarantees predictable results and specialized follow-up.

SADI-S is indicated for patients with:
Each patient is comprehensively evaluated at the Clínica 3 de Mayo, with nutritional, endocrinological, and psychological studies prior to the procedure.
The procedure is performed laparoscopically or robotically, with small incisions and a quick recovery. The procedure lasts between 2 and 3 hours and requires an average hospital stay of 2 to 3 days.
Dr. Lago’s team applies minimally invasive surgical techniques and accelerated recovery protocols, which reduce pain, improve comfort, and shorten the time it takes to return to normal life.
Patients experience progressive and sustained weight loss:
In addition to weight loss, there is an improvement or resolution of associated diseases:
Recovery is gradual and carefully monitored. During the first few weeks, patients follow a liquid diet, then a semi-soft diet, until they gradually return to a normal diet.
Follow-up includes laboratory tests, adjustment of vitamin supplements, and psychological support. In the medium term, patients report a better quality of life, increased energy, and metabolic stability.
Dr. Jesús Lago explains the SADI-S operation.
On average, 80-90% of excess body weight is lost. This means that a person with 60 kg of excess weight can lose between 45 and 54 kg. The result depends on dietary compliance and regular check-ups with the medical and nutritional team.
No, SADI-S is not reversible. However, by preserving part of the functional bowel and making only one anastomosis (one connection), nutrient absorption is better than in the classic bypass or the original duodenal switch. This allows a more stable balance between weight loss and nutritional maintenance.
Like all major surgery, it may involve anesthetic risks, bleeding or infection, although its complication rate is very low when performed by an experienced team. In the long term, some patients may require chronic vitamin supplements, especially iron, calcium, vitamin D and B12. At Mayo Clinic 3, the follow-up protocol allows early detection and correction of any nutritional alteration.
The SADI-S offers superior weight loss and better metabolic control in patients with severe obesity or advanced type 2 diabetes. In addition, by having only one anastomosis (one intestinal junction), it reduces the risk of leaks and complications with respect to the classic bypass. However, the choice of technique depends on the patient’s individual profile, which is determined after a complete medical evaluation.
Most patients can resume daily activities after 10-14 days. Moderate physical exercise is recommended from the first month, and return to work is usually possible within 3 to 4 weeks after surgery.
Yes, SADI-S is one of the most durable techniques in terms of sustained weight loss. At 5 years, more than 80% of patients retain at least 70% of the weight lost, proving its long-term effectiveness when combined with a healthy lifestyle.
