Undiagnosed versus diagnosed Type 2 diabetes

The charts below can help explain to a just-diagnosed Type 2 diabetes, how food impacts on blood sugars, and how having insulin can improve their health by returning their blood sugar to the normal range more quickly.

Pre-diagnosis – no Insulin

Meal eaten at 8am takes 3.5 hours to return to normal blood sugar levels.

After Diagnosis – with Insulin Treatment

Here 2 units of Humalog was delivered with the meal, and the return to normal blood sugars takes 90 minutes less, and the peak goes from 15.2 to 13.0.
