Questions

Common questions

Why does the overweight threshold begin at BMI 23?

Asian-population screening guidance commonly uses lower action thresholds than the general international BMI categories because health risk can increase at a lower BMI.

Can BMI diagnose a health condition?

No. BMI is a screening ratio and cannot replace clinical assessment.
