The objective of the present invention is to provide a hemodialysis system optimized, for example, to suppress fluctuations in blood pressure in accordance with differences between individual patients. This system is configured to include: a blood-related information acquiring means for acquiring blood flow information in a hemodialysis blood circuit, and patient biometric information such as peripheral vascular resistance information, blood pressure information, facial information, body movement information, temperature information, and humidity information； an individual difference information management means for acquiring and managing patient individual-difference information from the blood-related information； and an optimized dialysis means for performing dialysis treatment optimized for the patient, on the basis of the patient individual-difference information.
