AI summary

Diabetes analysis system for analysis and interpretation of data related to glucose level (GL) in blood, the system is to be applied to determine a treatment recommendation to a patient. The analysis system comprises an input module (2) configured to receive GL related data (4) from measurements of interstitial fluid in subcutaneous tissue. The system further comprises a hypoglycemia identification module (6) configured to identify hypoglycemic events by performing a computer-implemented automatic search of said received GL related data, wherein all uninterrupted glucose levels less than a predetermined level, e.g. glucose levels < 3.5 mmol/L, in a same time series will be considered as one hypoglycemic event, and a hypoglycemia classification module (8) configured to analyze, for each identified hypoglycemic event, the glucose data during a predetermined first time period, e.g. three hours, preceding the hypoglycemic event, to determine the glucose level during the first time period, wherein the hypoglycemia classification module is configured to determine the type (10) of hypoglycemia event, based upon the glucose level during the first time period, by applying a computer-implemented pattern search procedure on a predetermined hypoglycemic classification scheme including different types of hypoglycemia, in order to identify the underlying cause of hypoglycemia.
