1. A wearable drug delivery system, comprising:
a reservoir configured to store a liquid drug;
a pump mechanism operable to expel doses of the liquid drug from the reservoir;
an inertial measurement unit operable to detect an activity level of a user; and
a controller communicatively coupled to the pump mechanism and the inertial measurement unit, wherein the controller is operable to:
automatically initiate an activity mode of operation based on a determined activity level change based on an input from the inertial measurement unit exceeding one or more activity mode thresholds, wherein the activity mode of operation is selected from a plurality of modes corresponding to different levels of activity;
modify parameters used in calculation of doses of the liquid drug to be delivered to a user; and
output a signal to cause actuation of delivery of the liquid drug via the pump mechanism according to the set activity mode.
