Body Mass Index

Body Mass Index (WHO Classification): Validated screening tool for weight categories and obesity assessment. In bariatric surgery, BMI ≥40 or ≥35 with comorbidities guides surgical candidacy. Updated 2024 guidelines recommend evaluation for patients ≥35 with obesity-related comorbidities like type 2 diabetes, hypertension, sleep apnea, or GERD.
