Provided is real-time blood glucose measurement using multiple body signals, and more particularly, a blood glucose measurement method and apparatus using multiple body signals, the method and apparatus employed to estimate blood glucose in a noninvasive manner by using a change in the absorbance of glucose according to a blood glucose level and correct the estimated blood glucose using different types of blood glucose measurement methods. The blood glucose measurement apparatus comprises: a main body which can be worn on a human body a first light source unit which is provided on an inner surface of the main body and contacts the human body wearing the main body a second light source unit which is provided on the inner surface of the main body and irradiates light in the same direction as the first light source unit a light receiving unit which receives light from the first light source unit and the second light source unit and a calculation unit which calculates a glucose level in blood based on the amount of light received by the light receiving unit and measures blood glucose using the calculated glucose level in the blood.
