A treatment system includes a massage machine and a measurement portion. The measurement portion obtains body information data of a subject to be treated and outputs and transfers the body information data to the massage machine. The massage machine includes a treatment portion that treats the subject, a control unit that controls the treatment portion, a storage portion that stores data of treatment courses and a treatment course notification portion that displays one of the treatment courses. The measurement portion and the control unit are connected. The control unit is configured to receive the body information data from the measurement portion, and selects a suitable treatment course from the treatment courses based on the body information data. The treatment course notification portion notifies of the suitable treatment course.
