Effective surgical treatment for obesity and associated diseases
Effective surgical treatment for obesity and associated diseases

Biliopancreatic bypass is one of the most effective techniques for the surgical treatment of obesity. Its objective is to achieve significant and lasting weight loss in patients with severe obesity or associated pathologies who have not achieved results with other procedures or medical treatments.
Dr. Jesús Lago, a specialist in bariatric and metabolic surgery at the 3 de Mayo Clinic, performs this procedure using a minimally invasive laparoscopic approach, ensuring faster recovery and less postoperative discomfort.
This technique combines two mechanisms:
In this way, the body absorbs less fat and carbohydrates, which translates into sustained weight loss and the improvement or even resolution of metabolic diseases such as type 2 diabetes, high blood pressure, or sleep apnea.
It is indicated in patients with morbid obesity (BMI > 40) or severe obesity (BMI > 35) associated with diseases such as diabetes, hypertension, or dyslipidemia.
It is a particularly useful technique when other restrictive surgeries (such as gastric sleeve or classic gastric bypass) are not sufficient or have lost their effectiveness over time.
Its objective is not only weight loss, but also improvement in overall health and remission of metabolic diseases.
Before the procedure, the patient undergoes a comprehensive evaluation that includes:
Dr. Lago and his team explain each stage of the process to the patient, from preoperative preparation to postoperative care, offering a personalized and safe approach.

After surgery, the patient experiences progressive and stable weight loss.
During the first few months, they follow a special transition diet to solid foods and receive continuous medical and nutritional monitoring.
As biliopancreatic bypass surgery reduces the absorption of certain vitamins and minerals (such as B12, iron, folic acid, and fat-soluble vitamins), it is essential to maintain regular supplementation and analytical monitoring.
The team at Clínica 3 de Mayo accompanies the patient throughout the process to ensure a safe recovery and optimal quality of life.
The Body Mass Index (BMI) is used to classify the degree of obesity and calculate ideal weight:
BMI = weight (kg) / height (m²)
A BMI greater than 40 is considered morbid obesity, the main indication for surgery.
The goal is to achieve a healthy BMI and maintain it over time, improving the patient’s physical and emotional health.
If you are considering biliopancreatic bypass surgery or have questions about which technique is best for you, request a free informational consultation at Clínica 3 de Mayo.
Dr. Jesús Lago explains the biliopancreatic diversion procedure:
Weight loss typically ranges from 70 to 80 percent of excess body weight during the first 18–24 months after surgery, depending on the patient’s commitment to diet and medical follow-up.
Most patients resume their daily activities within 10–12 days. Return to work depends on the type of job and individual progress.
Yes, although in smaller amounts and gradually. Unlike other surgeries, this technique allows for a more varied diet, but always under the guidance of the medical and nutritional team.
Yes. It is common to take vitamins and minerals on an ongoing basis to compensate for reduced intestinal absorption. This is monitored through regular checkups.
This technique generates the greatest weight loss and achieves the highest remission rate for metabolic diseases. However, it requires stricter monitoring and commitment on the part of the patient. It is not suitable for people who eat mainly carbohydrates.
As with any major surgery, there may be risks, although they are rare. These include nutritional deficiency, diarrhea, or the need for surgical revision. The key is constant medical monitoring and follow-up.
