Patent Images
1. A method for predicting future blood glucose values from blood glucose data collected over time for a patient, comprising:
- measuring blood glucose data at selected times over a selected sampling period;
collecting data related to insulin delivery, carbohydrate intake and exercise over the selected sampling period;
determining values for selected patient specific parameters from the blood glucose data, insulin delivery and meal data;
providing the determined values to a model to determine a patient'"'"'s reaction to insulin therapy, carbohydrate intake and exercise;
processing the model to provide a model output;
predicting the patient'"'"'s future blood glucose values from the model output.

Abstract
Various methods for improving the use of model based prediction of future blood glucose control in a patient having diabetes are described. A system for processing diabetes related information, including glucose information, for accurately predicting future glucose levels as a function of glucose data, carbohydrate intake, insulin delivery history and exercise history and then providing recommendations related to the predicted future glucose levels, is also described.
