## Abstract

A method of managing insulin includes receiving blood glucose measurements on a computing device from a glucometer. The blood glucose measurements are separated by a time interval. The method includes determining, by the computing device, an insulin dose rate based on the blood glucose measurements and determining a blood glucose drop rate based on the blood glucose measurements and the time interval. The method also includes determining a blood glucose percentage drop based on the blood glucose measurements. The method includes decreasing the time interval between blood glucose measurements by the glucometer when the blood glucose drop rate is greater than a threshold drop rate, and decreasing the time interval between blood glucose measurements by the glucometer when the blood glucose percentage drop is greater than a threshold percentage drop.
