The invention relates to a device for determining physiological data through analysis of human excrement in a toilet (T) by means of at least one indicator and/or sensor, and to a method for determining physiological data by analysis of human excrement in a toilet (T) by measurement of urine and/or stool values. The problem addressed by the invention is that of achieving maximally universal use of the device and thus broad dissemination, including in the case of a wide variety of toilet designs, with reasonable design effort and manageable costs. This problem is solved by a measurement system, in which an indicator (11′) or sensor can be brought into a measurement position, in which sufficient contact with the urine or stool to be examined occurs, by means of an arm (10′) for each measurement, wherein the indicator (11′) or sensor is/are designed as (an) independent unit(s), and by a corresponding method in which a plurality of previously determined values are measured and then processed further and forwarded as applicable.
