Are You a Candidate?
Who qualifies for bariatric surgery?
According to international criteria, the following patients may be candidates for bariatric surgery:
BMI ≥ 40 (severe obesity)
Patients with a body mass index of 40 or higher, even without associated diseases.
BMI ≥ 35 with comorbidities
Type 2 diabetes, hypertension, obstructive sleep apnea, dyslipidemia, degenerative joint disease, or non-alcoholic steatohepatitis.
BMI 30–34.9 with poorly controlled type 2 diabetes
Patients with grade I obesity and type 2 diabetes who cannot achieve adequate metabolic control with medical treatment (metabolic surgery).
Failed previous treatments
Patients who have tried to lose weight through diet, exercise, and/or medications without sustained results for at least 6 months.
Favorable comprehensive evaluation
Multidisciplinary assessment (nutritional, psychological, medical) confirming the patient as a suitable candidate committed to lifestyle changes.
The final indication should always be made individually by a board-certified bariatric surgeon, taking into account the complete medical history, patient expectations, and associated risks.
