1. What is BMI Calculator For Amputation?

Definition: This calculator estimates Body Mass Index (BMI) for individuals with amputations by adjusting for the percentage of body weight lost.

Purpose: It provides a more accurate health assessment for amputees by accounting for missing limb mass in BMI calculations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( BMI \) — Adjusted Body Mass Index (kg/m²)
• \( W \) — Current weight (kg)
• \( P \) — Percentage of body weight amputated (decimal)
• \( H \) — Height (meters)

Explanation: The current weight is adjusted upward to estimate what the weight would be with the missing limb, then divided by height squared.

3. Importance of Adjusted BMI for Amputees

Details: Standard BMI calculations may underestimate obesity in amputees. This adjusted BMI provides a more accurate health assessment.

4. Using the Calculator

Tips: Enter current weight in kg, percentage of body weight amputated as a decimal (e.g., 0.10 for 10%), and height in meters. All values must be > 0 (percentage must be < 1).

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my percentage of body weight amputated?
A: Use standard tables that show what percentage of total body weight each limb represents (e.g., whole arm ≈ 5%, whole leg ≈ 16%).

Q2: Why is adjusted BMI important for amputees?
A: Standard BMI would classify many amputees as underweight when they may have normal or excess body fat percentage.

Q3: What's a healthy BMI range for amputees?
A: The same ranges apply (18.5-24.9 normal), but consult your healthcare provider for personalized assessment.

Q4: Does this work for multiple amputations?
A: Yes, simply add the percentages for all amputated limbs (e.g., 0.16 for one leg + 0.05 for one arm = 0.21 total).

Q5: How accurate is this calculation?
A: It provides a good estimate but may not account for all factors like muscle mass. Always consult a healthcare professional.
