A blood sugar monitoring system (10) as an analyte monitoring system is provided with a sensor (12) which detects a plurality of blood sugar levels in blood on the basis of a sampling interval, a meal data setting unit (48) which sets information based on meal contents, and a sampling interval setting unit (50) which sets the sampling interval of the sensor (12) using the information based on meal contents set by the meal data setting unit (48). By predicting a fluctuation curve of the blood sugar level after a meal by information based on meal contents to thereby change the sampling interval, a fluctuation state of the blood sugar level can be efficiently monitored.
