Diagnosis and Symptoms
Question from Massachusetts, USA:
Is hyperglycemia considered diabetes? If so, what type?
Answer:
A confirmed fasting blood sugar of 126 mg/dl [7mmol/L] and/or random blood sugars of 200 mg/dl [11.1 mmol/L], done in a laboratory on two separate occasions, are considered diagnostic of diabetes, but abnormal blood sugar levels do not distinguish between the various types of diabetes.

Additional comments from Dr. Andrea Scaramuzza:
It is necessary to know which is the value of the hyperglycemia. In fact, a glycemic level higher than normal it is not to be considered diabetes by itself. It could be a transient hyperglycemia, that has to be tested for diabetes periodically.

[Editor’s comment: Also, there can be mildly elevated blood sugars (or in the medical jargon, hyperglycemia) that’s not high enough to meet the diagnostic criteria for diabetes (which Dr. O’Brien gives above). So, there can be hyperglycemia without automatically making a diagnosis of diabetes.
Recently, the American Diabetes Association has publicized the concept of prediabetes (instead of the old cumbersome term of “impaired glucose tolerance”) to give a short and snappy name to this situation of mildly elevated glucose levels.
