Analyte monitoring systems and methods may include calculating an analyte level and an analyte level rate of change using at least measurement information conveyed by an analyte sensor, displaying the analyte level, determining whether the analyte level is lower than a first lower analyte level threshold, determining whether the analyte level is lower than a second lower analyte level threshold, comparing the analyte level rate of change to an analyte level rate of change threshold, and displaying one or more of a low analyte level alert and a rate of change alert. The low analyte level alert may be displayed if the analyte level is lower than the first lower analyte threshold, and the rate of change alert may be displayed if the analyte level is lower than the second lower analyte level threshold and the analyte level is changing faster than the analyte level rate of change threshold.
