đWHO South Asian vs International BMI Categories
Due to higher body fat percentages and elevated cardiovascular risks at lower weights, WHO established lower cutoffs (23.0) for South Asian populations.
| Category | South Asian WHO (Ours) | Western WHO | Clinical Risk |
|---|---|---|---|
| Underweight | < 18.5 | < 18.5 | Malnutrition & low immunity |
| Normal / Ideal | 18.5 â 22.9 | 18.5 â 24.9 | Lowest clinical health risk |
| Overweight | 23.0 â 27.4 | 25.0 â 29.9 | Hypertension & diabetes risk |
| Obese | âĨ 27.5 | âĨ 30.0 | High cardiovascular & stroke risk |

Best Practices for Accurate Results
- Always input recent, verified laboratory reports or precise physical tape measurements.
- Record blood pressure or weight at the same time of day under resting, standardized conditions.
- Do not alter prescribed medications or self-treat based solely on automated calculator scores.
This calculator provides risk stratification and clinical screening insights. In evidence-based medicine, numerical scores are always interpreted alongside complete patient history, physical examination, and comprehensive laboratory diagnostics.
If your calculated score falls within a high-risk or critical range, or if you experience warning symptoms like acute shortness of breath, severe chest pressure, sudden confusion, or fluid retention, consult the matched Khulna specialists below immediately.
