Diagnosis and Symptoms

Question from West Virginia, USA:

During a fasting three hour glucose test, my daughter obtained the following results: fasting - 95 mg/dl [5.4 mmol/L]; two hours - 208 mg/dl [11.6 mmol/L]; and three hours - 48 mg/dl [2.7 mmol/L]. What does this mean?

Answer:

She could be in the early stages of diabetes, especially if she is overweight and has beginning insulin resistance. She should have had simultaneous insulin levels drawn with the glucose levels to determine this. If she has acanthosis nigricans, high lipids, hypertension or polycystic ovary syndrome, this would also be associated with such early insulin resistance. The last value is actually hypoglycemic and this could represent excessive insulin production later in the test. You should consult with a pediatric endocrinologist for more detailed information and follow-up testing.
