QUESTION: Pls advice what i should do: my test shows fasting 108mg/dl and after breakfast 217mg/dl.

Pls advise me whether this is high or acceptable? I have already stopped all sugar related things. Pls advice asap thanks and god bless you sir.


ANSWER: Hi Austin,

The normal blood glucose level is between 64.8- 104.4 mg/dl. However, slight deviations are acceptable, like in your case a result of 108 mg/dl.

But the thing, which bothers me, is the postprandial blood glucose level of 217mg/dl; because the normal blood glucose level after having a meal has to be less than 180mg/dl.

However, you haven’t mentioned when the postprandial blood glucose test was performed, because if the test was run 10-20 min after the meal, an elevation like this is normal. However, if the test was made 2 hours after having a meal, this result is not normal.

There are two explanations for these elevations. The first is related with your diet, because if you are eating foods, which are rich in carbs, such blood glucose elevations are going to be normal.

The second explanation is related with the changes in the glucose metabolism, because if there is reduced insulin secretion, the blood glucose of yours will be elevated.

Interesting fact is that you haven’t mentioned anything about any possible symptoms of diabetes. Because of this, I want to ask you, have you notices lately permanent thirst, frequent urination or the increased hunger.

All these three are regarded as symptoms of diabetes and the combination between them and a blood glucose elevations are leading to confirmation of diabetes as diagnosis.

However, in purpose to confirm or exclude diabetes as diagnosis, make a consultation with your doctor and ask him for the glucose tolerance test.

During this test, your doctor will give you a cup full of 75 ml of glucose, which you have to drink. After this, blood samples are going to be taken every 15-30 minutes, which will serve for a blood glucose measurement.

With this test your doctor will understand how your body is able to handle with glucose consumption.

Hope it helped!
