A lot of the daily fluctuations in weight, even in just everyday life for people not in hospitals, involves changes in water weight rather than actual changes in the tissue mass. For example, I regularly fluctuate +/- 3lbs or so around my true weight over the course of a day. Looking at daily values can give a distorted picture, but if you use those daily weighings to average into weekly numbers, you can track changes.
