In this article the authors performed numerical analysis of glycemic regulation mathematical model described by two differential equations with one delay argument. The results obtained in the linear analysis [3] were used in numeric analysis constructing solutions applying the Runge-Kuto IV successive method in normal and diabetes cases. Diabetes medical strategy will be modeled to the above-mentioned model (2.1)–(2.2) introducing two external periodic functions determining food and exogenous insulin injections. Treatment strategy will be modeled applying a scientific simulation modeling program „Model Maker“.
