1. A sensor device for producing data indicative of an analyte level of a user, the sensor device comprising:
- a sensor that measures an analyte level of a user;
sensor electronics coupled to the sensor that receive and process the measured analyte level to generate analyte data;
a bolus estimator that receives the analyte data from the sensor electronics and estimates a bolus amount of medication to be dispensed from a single dose medication device based on the analyte data and information about an intended meal planned to be consumed by the user, wherein the bolus estimator includes a memory that stores one or more databases used in estimating the bolus amount; and
a monitor coupled to the bolus estimator that displays a user interface, the monitor having one or more inputs that are used to enter and receive said information about the intended meal, and wherein the user interface displays the estimated bolus amount, wherein;
the sensor device prompts the user to report events when significant changes in the analyte level are sensed, said events being selected from the group consisting of exercise, medication intake, and type of medication device used;
the sensor device calculates user sensitivity based on the reported events;
the bolus estimator estimates the bolus amount based on the calculated user sensitivity; and
based on said analyte data, said information about the intended meal, and said one or more databases, the bolus estimator provides a recommendation of a suggested meal, said suggested meal being different from said intended meal.

Abstract
An analyte sensor and systems for determining analyte levels in a user'"'"'s body. The analyte sensor and systems are adapted to be used with single dose medication devices and include a communication system to transmit the communications from the analyte sensor to the user to notify the user of an estimated amount of fluid to deliver to the user'"'"'s body. More particularly, these apparatuses and methods for use are for providing convenient monitoring of blood glucose levels in determining the appropriate amount of insulin to deliver.
