Study of the Effects of Carbohydrate Counting

The Effect of Carbohydrate Counting and Bolus Calculation Using an Electronic Calculator in Carbohydrate Counting-naïve Persons With Non-optimally Treated Type 1 Diabetes

The investigators hypothesize that non-optimally treated carbohydrate counting-naïve patients with type 1 diabetes can achieve better metabolic control by counting carbohydrates and that the metabolic control can be further improved with concurrent use of an integrated glucose meter and bolus calculator. The investigators want to test the hypothesis in this study.
