Method of monitoring blood sugar and electronic device supporting same

A wearable electronic device comprising:

• a first sensor;
• a second sensor;
• a memory;
• and
• a processor operatively connected to the first sensor, the second sensor, and the memory,
• wherein the processor is configured to:
• measure a blood sugar level of a user in a first cycle using the first sensor so as to store a first blood sugar level measured at a first time point according to the first cycle in the memory,
• detect a specified event, based on measured values received from the second sensor from a second time point after the first time point to a third time point,
• in case that the specified event is detected, measure the blood sugar level of the user in a second cycle different from the first cycle using the first sensor so as to store at least one second blood sugar level measured from a fourth time point to a fifth time point according to the second cycle in the memory, and
• calculate at least one feature value related to blood sugar of the user, based on the first blood sugar level and the at least one second blood sugar level.
