Abstract: A system determines onset of a prediabetic state and associated risk of type 2 diabetes without evidential symptoms. In an implementation, a computer implemented method for monitoring an onset and progress of prediabetes in an individual includes periodically capturing an insulin level of an individual and a blood glucose level of the individual over a predetermined time interval for a predefined period, deriving an insulin production trend or a relative insulin resistivity trend over the predefined period, wherein the relative insulin resistivity is a ratio of an insulin level and a blood glucose level, wherein the trends are indicative of trend categories comprising an increasing trend, a steady trend and a decreasing trend, and determining a status of prediabetes in the individual based on at least one of the insulin production trend, relative insulin resistivity trend, and personal data of the individual.

Abstract: The invention provides method and system for calculating indices for diabetes control. The method and system involves collecting a plurality of blood glucose (BG) data of a subject and calculating a Blood Glucose Control Index (BGCI) value and a Severe Hypoglycemia Risk Index (SHRI) value based on parameters calculated using the plurality of BG data. The BGCI and SHRI values reflects a current state of diabetes of the subject. Further, the BGCI and SHRI values provides an indication if the subject may face a secondary complication associated with diabetes, such as, severe hypoglycemia in the future.
