29.What can happen if my diabetes is not properly treated and controlled?
Uncontrolled diabetes, which generally refers to glucose levels that are higher rather than lower than the target range, can lead to immediate short-term and longer term consequences. The short-term consequences result from the very high blood glucose itself, which is described in Question 4.
If severe enough or untreated for long enough, markedly high blood glucose levels can result in coma and ultimately death, due to the severe abnormalities of blood chemistry that occur. It is important to note that only a very small minority of patients with either form of diabetes will die in this way.
