Disclosed are a human body wearable body information measuring device and a medical support system based on the same. The device comprises: a plurality of light sources capable of emitting beams having a plurality of different wavelengths to a body portion of a wearer； a light receiving element receiving beams which are emitted from the plurality of light sources and reflected and scattered by the body portion of the wearer, and converting the received beams into electrical signals； a blood sugar analyzing module analyzing electrical signals of the light receiving element to obtain the signal amount of a pulse wave type signal corresponding to each of the wavelengths, and calculating the blood sugar level of a subject to be measured by using a difference signal amount between a pre-input reference value (reference signal amount) and the signal amount obtained from the body of the subject to be measured； a blood pressure analyzing module analyzing a pulse wave formed by the sensed signal of the light receiving element to distinguish between an incident wave and a reflective wave, detecting the PRT and the pulse pressure, and deriving a blood pressure value through a predetermined calculation procedure including a process of multiplexing the pulse pressure by a first coefficient and multiplexing the PRT by a second coefficient to add the multiplexing results； and a communication device capable of transmitting, to the outside through a nearby communication means, patterns and the blood sugar and blood pressure values of the subject to be measured, which are obtained by the blood sugar analyzing module and the blood pressure analyzing module. According to the present invention, the accurate wearer body information including the blood pressure and the blood sugar level obtained by the measuring device can be transmitted periodically or in real time to a relevant nursing institution or a medical institution such that remote efficient management can be achieved and quick r
