FIELD

This disclosure relates to an electronic device and a method for controlling the same. More specifically, the disclosure relates to an electronic device for providing real-time blood glucose information by improving a blood glucose prediction error based on blood flow and heart rate information of a user sensed through a sensor, and a method for controlling the same.

DESCRIPTION OF THE RELATED ART

A continuous glucose monitoring system (CGMS) is a system for continuously measuring blood glucose and providing measured blood glucose on a real time basis, even if a patient with hypoglycemia or hyperglycemia does not visit a medical staff.

However, most of continuous glucose sensors (CGS) used in CGMS measure blood glucose (BG) by sampling interstitial fluid glucose (IG) of interstitial fluid. Therefore, the method of predicting the blood glucose by the glucose sensor is, when the glucose included in the blood (BG) diffuses into the glucose in interstitial fluid (IG), measuring by the glucose sensor the IG level of the interstitial fluid and predicting the BG in the blood. Therefore, the level of blood glucose predicted by the CGMS is not from measuring the blood glucose of actual blood vessels and thus, an error of blood glucose measurement due to a time delay caused by the diffusion of glucose from the blood into the interstitial fluid is generated.

However, in the case of a patient with the hypoglycemia, the blood glucose falls within a short period of time and the patient may be in a light-threatening situation. Therefore, there is a need for a technology for developing the CGMS which minimizes the time delay between the glucose level of the blood vessel and the glucose level of the interstitial fluid, in order to predict and provide accurate blood glucose.

Also, with the development of ubiquitous technology, real-time monitored blood glucose information may be shared with medical staff and emergency centers. Therefore, there is a need for various technologies which may provide the CGMS optimized for a patient with the hypoglycemia and a patient with the hyperglycemia based on the accurate blood glucose measurement result, and enable remote diagnosis and prescription by a medical institution.
