Its a condition of high glucose level in your blood which also leads to glucose excretion in urine.
What causes Diabetes Mellitus ?
Glucose enters into our cells when our hormone insulin, binds to cells. Due to genetic or some environmental reasons, such glucose entry doesn't occur even after binding of insulin to the cells (also known as INSULIN RESISTANCE). In some cases there may be deficiency of insulin itself. In both these instances glucose doesn't utilize by our body and ultimately leads to rise in glucose level in our blood which is known as Diabetes Mellitus.
