1. An estimation system comprising:
a communication interface configured to communicate with an apparatus and receive information about a subject;
a sensor configured to acquire a pulse wave of the subject;
a controller configured to estimate a blood glucose level and/or a lipid level of the subject based on a displacement ratio in the pulse wave, the displacement ratio comprising a ratio between a displacement of the pulse wave at a peak of the pulse wave and a displacement of the pulse wave at a predetermined time after the peak of the pulse wave; and
a notification interface comprising a speaker, a vibration unit, or a display device,
wherein the communication interface sends a notification regarding the estimated blood glucose level and/or the lipid level of the subject to the apparatus,
wherein the notification interface is configured to provide the notification of the estimated blood glucose level and/or the lipid level of the subject, and
wherein the predetermined time is a fixed value.
