QUESTION: I am 59 years old. My fasting glucose was 154 mg/dL and my reading 2 hours after breakfast was 269 mg/dL. Another random blood sugar test was 106 mg/dL. My urine sugar 2 hours after breakfast was 3+ and this is the first time I have been tested. I also had a reading reported as Hb 11.7 g/dL. I take Cresar/Cresar AM 40 daily at night. Please advise.
Your fasting glucose of 154 mg/dL is in the diabetes range if it was a properly performed laboratory fasting test. A glucose of 269 mg/dL two hours after breakfast is also clearly high.
The later random glucose of 106 mg/dL does not cancel these abnormal results because blood sugar can change considerably during the day. Your urine glucose of 3+ also supports that your glucose became high enough for sugar to spill into the urine.
You should arrange a medical appointment soon for a repeat laboratory fasting glucose, HbA1c, and further evaluation. One set of results should not be used by itself to make a final diagnosis when there are no clear symptoms of severe hyperglycemia.
Answer by Dr. Albana Greca, MD, MMedSc
Hello K J Rao,
I would not ignore these results. The fasting and after-breakfast readings are both significantly elevated, even though your later random glucose was normal.
A true fasting plasma glucose is measured after at least 8 hours without food or caloric drinks.
| Fasting glucose | Interpretation |
|---|---|
| Below 100 mg/dL | Normal range |
| 100–125 mg/dL | Prediabetes range |
| 126 mg/dL or higher | Diabetes range when confirmed |
Your result of 154 mg/dL is therefore above the diagnostic threshold and needs confirmation. See our guide to fasting blood sugar between 127 and 200 mg/dL.
A two-hour glucose of 269 mg/dL is high. A normal breakfast is not the same as a formal oral glucose tolerance test, so this reading alone should not be interpreted as an OGTT result. However, it strongly supports the need for further evaluation.
For many adults who already have diabetes, a commonly used treatment target is below 180 mg/dL about 1–2 hours after the start of a meal. Your 269 mg/dL result is well above that level.

This difference can happen. Blood glucose is constantly changing depending on meals, activity, insulin release, stress, illness, hydration and the time of testing.
A random glucose of 106 mg/dL is reassuring for that particular moment, but it does not erase a fasting glucose of 154 or an after-meal glucose of 269.
Normally very little glucose appears in urine. When blood glucose rises sufficiently, the kidneys begin allowing glucose to spill into the urine. A result of 3+ glucose therefore supports significant hyperglycemia around the time the urine sample was collected.
Urine glucose cannot diagnose diabetes by itself and should not replace blood testing.
I recommend arranging a medical review and asking about:
HbA1c will help show your average glucose over approximately the previous 2–3 months. Learn more in our guide to HbA1c and average glucose.
If by “Hb 11.7 g/dL” you mean your hemoglobin concentration, this may be below the normal range depending on your sex and your laboratory's reference values. It should be reviewed separately with your doctor.
This is also worth mentioning before interpreting an HbA1c result because some forms of anemia can affect HbA1c accuracy.
If the medicine you mean is Cresar or Cresar AM 40, it is generally prescribed for high blood pressure. It is not a diabetes medicine.
Continue it exactly as prescribed and bring the medicine strip or prescription to your appointment so your doctor can confirm the exact formulation. Do not start diabetes medication on your own.
Seek urgent medical care if very high glucose is accompanied by vomiting, severe weakness, confusion, marked dehydration, abdominal pain, rapid breathing, severe drowsiness or inability to keep fluids down.
Also arrange prompt medical review if glucose readings repeatedly remain very high, even if you feel well.
Your random glucose of 106 mg/dL is reassuring at that moment, but I would place greater importance on the fasting result of 154 mg/dL and the 2-hour after-breakfast result of 269 mg/dL.
Because this was your first evaluation, the next step is not to panic or start medication yourself. Arrange confirmatory laboratory testing, particularly fasting glucose and HbA1c, and discuss the results promptly with your doctor.
