Patient with Type 1 Diabetes Glucose and insulin levels during OGTT To further characterize the pathology of the this patient, we performed an oral glucose-tolerance test, which is shown on this slide. As expected, -cell function was severely impaired with almost no increase in insulin secretion after oral glucose stimulation in our diabetic patient, in red, compared to a healthy familiy member, shown in green. The most strikingly point was, that, for a Type 1 diabetic patient, basal insulin levels were very high, even when compared to the control CELL Metabolism 17:448–455, 2013
