About This Calculator

Estimated body weight loss (EBWL) describes the amount of body mass lost due to an amputation. EBWL is most commonly utilized for determining an amputee's ideal body weight, which is a function of patient height. An EBWL-adjusted ideal body weight is most commonly used for determining renal function with creatinine clearance.

Estimated Body Weight Loss (EBWL) Table

The following estimates are reasonable for determining a patient's amputation ideal body weight (or adjusted body weight for overweight patients).^1,2

Ideal and Adjusted Amputation Body Weight

For patients without amputations, an ideal body weight equation (as described by Devine 1974) is calculated according to the equation below. For patients with amputations, the EBWL is used to calculate a percent of predicted ideal body weight:³

Adjusted body weight

In patients who are more than 30% of an amputation ideal weight, an "amputation adjusted weight" may be used. This adjusted body weight uses an adjustment factor of 0.4 (or 40%). Adjusted body weight is commonly used for calculations like creatinine clearance.
