An intracardiac electrogram (IEGM) or other suitable electrical cardiac signal is sensed. Values representative of a pre-symptomatic physiologic response to a hypoglycemic event are derived from the cardiac signal. Then, hypoglycemia is detected based on the values representative of the pre-symptomatic physiologic response. In one example, both temporal morphological parameters and spectral parameters affected by pre-symptomatic hypoglycemia are derived from the cardiac signal. Hypoglycemia is then detected based on a combination of the temporal and spectral parameters using, e.g., a linear discriminator. By detecting hypoglycemia based on parameters affected by pre-symptomatic hypoglycemia, suitable warnings can be generated and therapies initiated before the condition becomes symptomatic.
