1. A method of preemptively alerting a user, the method comprising:

  • obtaining, by a control module from a sensing arrangement, a first measurement value for a physiological condition in a body of the user at a first time, the physiological condition being influenced by a fluid delivered by an infusion device;

    determining, by the control module, a homeostasis metric indicative of an expected state of the physiological condition of the user in the future based at least in part on the first measurement value and a first amount of active fluid in the body of the user at the first time;

    automatically generating a preemptive alert on a display device coupled to the control module based on the homeostasis metric; and

    after automatically generating the preemptive alert;

    obtaining, by the control module from the sensing arrangement, a second measurement value for the physiological condition of the user at a second time after the first time;

    determining, by the control module, an updated value for the homeostasis metric based at least in part on the second measurement value and a second amount of active fluid in the body of the user at the second time; and

    automatically removing, by the control module, the preemptive alert from the display device based at least in part on the updated value for the homeostasis metric.
