Tandon et al adjusted body weight in patients with cirrhosis to take into account fluid accumulation as ascites or pedal edema. This dry weight may give a more accurate body mass index. The authors are from the University of Alberta, University of Waterloo and University of Calgary.

Patient selection: cirrhosis with a history of ascites



(1) scale weight on kilograms

(2) weight after paracentesis in kilograms

(3) degree of ascites (mild, moderate, severe)

(4) bilateral pedal edema


First adjustment: Adjust the scale weight for ascites by using one of the following:



Multiply Scale Weight By

immediate post-paracentesis


with mild ascites


with moderate ascites


with severe ascites



Second adjustment: If bilateral pedal edema is present, then subtract an additional 5%.


adjusted weight =

= (unadjusted weight) * 0.95


BMI for dry weight =

= (adjusted weight) / ((height)^2)
