Systems and methods for capturing and analyzing hypoglycemic event data
Systems, methods, and computer readable storage media manage low blood glucose levels. The system receives blood glucose readings, where each reading includes a blood glucose value and a respective timestamp. The system compares each blood glucose reading to a predefined hypoglycemic event threshold, and identifies hypoglycemic events when a respective blood glucose reading is below the predefined hypoglycemic event threshold. For at least a subset of the identified hypoglycemic events, the system prompts a user for information associated with each hypoglycemic event. The information requested includes one or more of: symptoms associated with the respective hypoglycemic event; perceived causes of the respective hypoglycemic event; and treatment for the respective hypoglycemic event. In response to the prompting, the system obtains feedback about the identified hypoglycemic events and provides a report that includes at least a subset of the obtained feedback.

13. The method of claim 11 , wherein the identified patterns indicate that the person is unaware when low blood glucose levels are occurring.
14. The method of claim 1 , further comprising:
analyzing the hypoglycemic events and the obtained feedback to identify one or more patterns of hypoglycemic events; and
including the identified patterns of hypoglycemic events in the provided report.
15. The method of claim 1 , wherein the provided report includes one or more recommended changes to activities of the person, and wherein the recommended changes are associated with exercising, eating, or taking medication.
