For patients identified as underweight or overweight, consider further nutritional or physical assessments and referrals as appropriate.
Individuals diagnosed with overweight or obesity should be counseled on diet and exercise.
In cases involving drug dosing, especially chemotherapy, regular monitoring and dose adjustments based on changes in BSA are necessary to optimize therapeutic outcomes.
Management
Management should not depend solely on BMI or BSA measurements, but on these values in conjunction with other body measurements and the overall clinical picture.
Critical Actions
A diagnosis of obesity can be made with a BMI of ≥30 kg/m2 alone; no further confirmatory testing or measurement is required (Rubino et al., 2025).
