Clinical Context

We think this might be relevant to the clinical guidance for Body Mass Index (BMI).

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.

Guidelines & Evidence

Last Review: 2026

When to Use

Primary Clinical Uses

Population-level metabolic screening and surveillance

Bariatric surgery candidacy (BMI ≥40 or ≥35 with comorbidity)

Eligibility screening for GLP-1 receptor agonists (semaglutide/liraglutide)

Monitoring progress in structured weight management programmes

Risk stratification for T2DM, hypertension, sleep apnoea, and CVD

When NOT to Use Alone

AMA 2023 policy explicitly recommends against using BMI as the sole criterion for clinical decision-making, particularly for bariatric surgery eligibility or pharmacotherapy access.
