Type 1 diabetes (T1D) is a chronic disease that requires those who live with it to regularly administer exogenous insulin to maintain blood glucose (BG) within a safe range. Insufficient insulin dosing can cause high glucose, leading to complications such as diabetic retinopathy, neuropathy, and cardiomyopathy. Too much insulin can cause low glucose, and when untreated, lead to coma or death. T1D-related complications can be reduced with proper diet, exercise, and adherence to an insulin dosing regimen. Decision support systems (DSS) can also help optimize glucose management by utilizing artificial intelligence (AI) and physician expertise to suggest adjustments to therapy parameters and behavior.
