A seamless and preferably substantially continuous health monitoring system, designed for use by a healthy living being but also suitable for non-healthy living being, the system including a control module, a communication unit and one or more sensors. The sensors can be in-vivo nano-sensors, micro-sensors, subcutaneous, wearable or implanted sensors. The control unit includes an analysis subsystem having a processing unit and an alerting unit. Each of the sensors is configured to detect a predetermined physiological or chemical parameter of the living being. The communication unit is facilitated to transmit the detected parameters to the analysis subsystem. The processor analyzes the detected parameters to thereby determine if the health state of the monitored living being is abnormal. When at least one detected parameter or the health state is determined to be abnormal, the alerting unit is operatively activated to alert a predetermined alert receiving entity.
