An apparatus comprising a pump configured to deliver insulin, an input configured to receive blood glucose data, a user interface, and a controller communicatively coupled to the pump, the input, and the user interface. The controller includes a blood glucose data module to compare the blood glucose data to a target blood glucose level for an insulin pump user. The controller is configured to present a question related to the blood glucose level via the user interface when the blood glucose level is different than the target blood glucose level, receive a response to the question via the user interface, and present a recommended user action based at least in part on the response. Other devices, systems, and methods are disclosed.
