Scroll down this page to see the effects of different insulin doses and regimens on the blood glucose profile of an example insulin-dependent diabetic patient.

The first graph in the panel below shows a 24-hour blood glucose profile for a typical patient (in red). His carbohydrate intake is shown in grams on the second graph (in green).

Blood Glucose Level (mmol/l)

The next panel below shows the patient's simulated plasma insulin level on the upper graph (in red), and his insulin regimen of Actrapid (in red) and Ultralente (in green) on the lower graph.

Plasma Insulin Level (mU/l)

This 35 year old insulin-dependent diabetic man recently switched to using an insulin pen, injecting three 'shots' of short-acting insulin before breakfast, lunch, and dinner, while taking a single dose of long-acting insulin before going to bed. However, he hasn't quite gotten full control of his blood sugars, still tending towards high blood glucose levels overnight. How might you improve his control, through adjusting his existing insulin doses?

For example, you could try moving his bedtime Ultralente injection to earlier in the evening - even perhaps combining it with his supper (19:30 hrs) Actrapid dose.

Below is a data entry form showing this example patient's carbohydrate intake, insulin injection regimen, as well as other clinical variables such as weight and renal function. Try changing any of these fields to modify the regimen and click on the 'Run Simulation' button at the bottom of the page. This will result in the effects of the changes being displayed in your Web browser window.

Click on the 'Run Simulation' button above to simulate the effects of your selected changes on the example patient's blood glucose profile. Once the next set of graphs is shown you can make further changes; the number of possible simulations which can be run is nearly infinite. 39 other cases are available for interactive simulation at AIDA on-line, and you can create further cases yourself. Enjoy!
