Increase in BMI Over Time Is Associated With Fluid Overload and Signs of Wasting in Incident Peritoneal Dialysis Patients

There is a mean increase in the BMI of incident PD patients over time, and these changes may be, at least partly, due to fluid overload, leading to distortions of body weight. When the patients presented with lower serum albumin or creatinine levels, the BMI values were reduced, suggesting that a reduction in lean mass and an increase in fat mass may be occurring in these patients.
