Effects of orthotopic liver transplantation on body composition

Abstract
Aims/Background: The effects of orthotopic liver transplantation on body composition are unclear. We aimed to assess changes in body composition after transplantation using dual energy x‐ray absorptiometry and total body potassium. Methods: Dual energy x‐ray absorptiometry and total body potassium counting to assess muscle mass were performed in 55 patients before and up to 24 months after liver transplantation and the results expressed as paired data before and at time intervals after transplantation. Results: The results showed that total body weight fell by 3.6 ± 1.3 kg (ppppppConclusions: After liver transplantation there is an initial fall in body weight due to a loss of lean mass. Lean mass does not recover after transplantation, although there is an increase in fat mass that leads to the observed increase in total body weight.
