Factors Affecting bmi amputation calculator
| Factor | Description | Impact | Typical Range |
|---|---|---|---|
| Weight | Current body weight without prosthesis | Higher weight increases BMI | 20-150 kg |

Frequently Asked Questions
Why is a special BMI calculator needed for amputees?
Standard BMI calculations assume a complete body, which can misrepresent weight status for amputees due to missing limbs. This calculator adjusts for limb loss.
How is BMI adjusted for amputations?
The calculator estimates the weight of missing limbs using standard percentages (e.g., 16% for a leg) and adjusts the current weight before applying the BMI formula: BMI = Adjusted Weight (kg) / (Height (m))^2.
How do I measure height for bilateral lower-limb amputees?
Use pre-amputation height or measure wingspan (tip of left middle finger to right middle finger, arms parallel to ground). Consult a rehabilitation specialist for accuracy.
What is a healthy BMI range?
A BMI of 18.5-24.9 is normal, less than 18.5 is underweight, 25-29.9 is overweight, and 30 or higher is obese. Consult a doctor for personalized advice.
Are there limitations to this calculator?
BMI does not account for muscle mass or body composition and may be less accurate for amputees with significant muscle or fat variations.
Tips for Accurate BMI Calculation
- Weigh yourself without prostheses, walkers, or wheelchairs for accurate weight.
- Use pre-amputation height or wingspan for bilateral lower-limb amputees.
- Select all applicable amputation types to ensure proper weight adjustment.
- Consult a healthcare provider to interpret BMI results in context.
- Use BMI alongside other health metrics (e.g., waist circumference) for a complete assessment.
