The purpose of this study is to learn how the amount of fluid in the body of a hemodialysis patient affects him or her. Body hydration is the amount of fluid in the human body and known to be related to blood pressure. Too much fluid can lead to high blood pressure which can cause heart problems and eventually lead to death. Bioimpedance Spectroscopy (BIS) is a method that may be used to measure body hydration. This can be applied in the whole body, arm, trunk, calf, and leg. It is a non-invasive and inexpensive method and no known risk. BIS measurements can be used to assess optimal hydration status which is defined as a patient's ideal weight after completing a dialysis treatment. The investigators hypothesize that your target weight may be better estimated by the BIS. The results of this study, in particular the continuous measurement of calf hydration which is associated with the hydration of the whole body, may provide useful information about physiologic ("healthy") body hydration. It may possibly help to improve treatment procedures for patients in the future. The Renal Research Institute plans to enroll 100 chronic hemodialysis patients and 200 healthy controls in this study.
