Interdialytic Weight Gain in Hemodialysis Patients: Worse Hospital Admissions and Intradialytic Hypotension

Abstract

Introduction: Interdialytic weight-gain (IDWG) has been linked to various complications in hemodialysis (HD) patients. Method: Prospective clinical-observational study to evaluate the effect of IDWG in HD patients on the rate of hospital admissions over a 12-month period, and the impact of high IDWG on the frequency of IDH. Results: Of the 240 patients, those who had IDWG ≥ 4%, 81% had at least one hospital admission due to volume-overload or the need for extra HD-session(s). On the other hand, only 19% of those having IDWG 4% in our patients), the same stands for the frequency of IDH. Thus, control of IDWG in HD patients is of great importance, keeping in mind the importance of the nutrition status of HD patients that may also impact IDWG.
