Obesity Surgery – Integrated Nutrition Clinic (Delta Hospital)

The Integrated Nutrition Clinic (INC) at Delta Hospital provides care, through a multidisciplinary team, for any adult struggling with obesity or wishing to make changes to their diet.

It is one of the busiest centres in Brussels for obesity surgery (bariatric surgery), with recognised expertise, state-of-the-art techniques and long-term follow-up.

Our expertise in bariatric surgery

Our team of gastrointestinal surgeons performs over 600 bariatric surgery procedures per year (657 in 2023, 579 in 2024, 630 in 2025).

This high-volume experience is a guarantee of safety and quality: in particular, it has enabled us to organise international workshops dedicated to ‘redo’ surgery, i.e. the management of patients whose initial operation did not produce the desired result. Robotic surgery is one of the tools we use.

Our surgeons work alongside a team of anaesthetists specialising in bariatric surgery, whose expertise facilitates a quicker recovery and a shorter hospital stay.

The offered procedures

Gastric bypass (gastric bypass surgery);
Sleeve gastrectomy (longitudinal gastrectomy);
Revision surgery following an initial bariatric procedure;
as well as medical and pharmacological approaches to weight loss, either as an alternative to or in addition to surgery.

Each surgical indication is discussed and approved during a multidisciplinary meeting, ensuring a collective, safe decision tailored to each patient.

A truly integrated clinic

three complementary areas of specialisation

The strength of the The Integrated Nutrition Clinic (INC) lies in bringing together, under a single coordination, all aspects of diet and nutrition.

Beyond obesity surgery, the clinic structures its activities around three complementary areas of specialisation:

Medical, nutritional and surgical management of excess weight and obesity.

The Cross-disciplinary Nutrition Unit (UTN), led by Dr Alexandra Collard and Prof. Jean-Charles Preiser, is dedicated to the screening and treatment of malnutrition.

A multidisciplinary team dedicated to complex cases (dysphagia, functional disorders).

This holistic approach, coordinated by Dr Anne-Catherine Dandrifosse, Head of the Integrated Nutrition Clinic (CIA), ensures patients receive continuity of care whatever their needs, whether they require surgery, treatment for malnutrition or management of a functional digestive disorder.

Lifelong care

Surgery is just one step…

Working alongside the surgeon, a multidisciplinary team (nutritionists, dietitians, psychologists, consultants in internal medicine, anaesthetists and physiotherapists) supports the patient both before and after the operation.

Long-term nutritional support is essential to prevent deficiencies and maintain a balanced body composition. This is the very essence of an ‘integrated’ clinic: bringing together, for each individual patient, all the expertise required for their long-term success.

Your journey, in your own language

Our nurse coordinators guide each patient through this in-hospital journey, in French, Dutch or English.

When surgery is being considered, the surgeon offers a personalised care plan: each patient follows their own unique pathway, based on a proven common framework.

Bariatric surgery: who is it for? Assess your situation

Bariatric surgery is generally intended for people with severe or morbid obesity.

Calculating your Body Mass Index (BMI) provides an initial guide:

BMI between 20 and 25: considered a normal weight
above 25: overweight; over 30: obesity
over 35: severe obesity; over 40: morbid obesity.

Calculate your BMI directly below. The decision to proceed with surgery is always made during a consultation following a comprehensive assessment.
