Abstract: The present disclosure relates to methods and systems for predicting glycemic events in a patient induced as a result of physical activity. In certain aspects, a method includes monitoring a plurality of analytes of the patient continuously during a time period to obtain analyte signals, the plurality of analytes including at least glucose and lactate. The method further includes processing the analyte data from the time period to determine signal-to-noise ratios of the analyte signal. The method then compares the signal-to-noise ratios to each other to determine if a sensor in the continuous analyte monitoring system is non-responsive. In alternative embodiments, a reference signal is obtained and a reference signal-to-noise ratio is compared to the analyte signal-to-noise ratio to determine if a sensor in the continuous analyte monitoring system is non-responsive.
