A method and system for evaluating a subject's weight calculates a moving average of the weight of the subject based on several consecutive weight measurements e.g. on consecutive days. Rather than looking for absolute weight gains of e.g. 2 kg in 48 hours, as with currently accepted guidelines, each new measurement is compared with the calculated moving average, and a first form of alert is generated if the new measurement differs from the calculated moving average by more than a with expected range threshold amount such as by one standard deviation. If the first form of alert is generated consecutively on a predetermined number of successive iterations, a second form of alert is generated different from the first form of alert. The system and method does not assume a stable underlying patient weight, and absolute weight gains over e.g. a 48 hour period are not used as in currently accepted guidelines, which results in earlier alerting of clinical deteriorations and greatly increased sensitivity relative to published guideline methods.
