In this paper the review of mathematical modeling of two phase blood flow in capillary is done with disease Diabetes .There are two phase of blood flow, one is RBC and other one is plasma. By the Fahreaus-Lindqvist influence the blood flow in two separated layers as transient from side to side capillaries, in which one layer is Newtonian and other is consider as Non-Newtonian layer. Further Non-Newtonian power law model is applied to bio fluid mechanical system. We have collected an observation data for patient having Diabetes. On the whole arrangement is in tensorial form and key method adapted is investigative as well as arithmetical. Later the graphical representation is also given for the data used here.
