To provide a therapeutic system which is based on the KAATSU training and which is suitable for treating metabolic syndrome. A therapeutic system is comprised of a tight fitting device 100, a body segment 200, a measuring segment 300, and a control segment 400. The tight fitting device 100 is wrapped around a predetermined range on the limb. The tight fitting device 100 has an air-tight gas bag and can change a compression pressure to be applied to the limb by means of introducing and removing air into and from the gas bag. The body segment 200 controls the flow of the air into and from the gas bag. The measuring segment 300 is attached to the limb around which the tight fitting device 100 is wrapped and measures the amplitude of pulse wave. The control segment 400 determines an air pressure within the gas bag at the time point at which the amplitude of the pulse wave reaches its maximum, during preprocessing that is performed prior to the treatment, and uses it as the pressure within the gas bag for the treatment.
