European Board Certification
The FEBS-MBS is the European fellowship in metabolic and bariatric surgery. This guide covers the exam, its format, eligibility, the topics tested and how to prepare.
FEBS-MBS is the Fellowship of the European Board of Surgery in Metabolic and Bariatric Surgery, issued by the UEMS Section of Surgery with IFSO and EAES. It certifies competency across the full bariatric surgical pathway.
The examination provides a harmonised European standard covering patient selection, operative technique, revisional surgery, metabolic physiology and complications.
Written Examination (computer-based)
FEBS-MBS is delivered as a computer-based multiple-choice examination covering the full metabolic and bariatric curriculum.
Indications & Selection
Patient selection criteria and preoperative workup.
Sleeve Gastrectomy
Technique, outcomes and complication management.
Roux-en-Y Gastric Bypass
Technique, outcomes and internal hernia management.
Revisional Surgery
Sleeve-to-bypass, SADI and endoluminal options.
Metabolic Physiology
Mechanisms of metabolic improvement and diabetes remission.
Nutrition & Complications
Micronutrient deficiency patterns after sleeve versus bypass.
The FEBS-MBS examination is held annually through the UEMS Section of Surgery. Applications open ahead of each sitting; confirm the current schedule, fees and eligibility with UEMS, IFSO and EAES.
FEBS-MBS is the recognised European subspecialty credential in metabolic and bariatric surgery, valued by accredited bariatric centres.
Preparation consolidates revisional decision-making and nutritional management — the areas that most differentiate safe, high-volume bariatric practice.
Use IFSO and EAES position statements as your primary references, master revisional decision-making (sleeve-to-bypass vs SADI vs endoluminal options), and know the micronutrient deficiency patterns after sleeve versus bypass. Practise timed MBS questions to build recall speed.
