BMI Calculator for Bariatric Surgeons designed by a me, a Bariatric Surgeon! This calculator does much more than just calculate BMI. It calculates Weight at BMI 24. I call this the Normal Weight. A more realistic value to shoot for than Ideal Body Weight. Also calculates Excess Body Weight and determines %Excess Body Weight Loss at 60% (for the Sleeve Gastrectomy), 70% (for the Gastric Bypass), and 50% (for the LapBand). It will then give you the expected weights at the corresponding %EBWL. It also help with Post Surgical Calculation with Total Weight Loss, Initial BMI, Current BMI, and %Excess Body Weight Loss. An Indispensable tool when talking with patients. No other calculator or tool out there on the Market! Believe me I scoured and that is why i designed it.
