High blood glucose 208 after having mango juice in a non-diabetic

QUESTION: I had mango juice this late afternoon and checked my sugar level one hour after the meal. It was 208. I have been checking my sugar levels of and on and they are normal.

Is it possible for a non-diabetic to get high reading like 208 once in a while?


ANSWER: Hi,

It is true that a blood sugar level of 208mg/dl is really high as the normal blood glucose level after having a meal is less than 180mg/dl. However, sometimes, due to consumption of meal rich in carbs, the blood glucose can be higher, just like in your case.

Normally, the blood glucose measurement after having meal, is estimated 2 hours after the meal consumption and not one hour like you did. The reason why the test is estimated 2 hours after the feeding is because the organism needs time to handle with the glucose acquired with the food.

Moreover, the organism needs time to transport the glucose from the food versus the cell in your body. With the two-hour period, we are ensuring the organism enough time to do those things and they we can see how much glucose has left unused in the blood.

Because of this, I can say that this result is normal. However, we want to be sure that everything is ok with your metabolism and my advice is to perform the blood glucose test tomorrow, two hours after having dinner or a meal in the late afternoon. I need you to check if the result is higher than 180mg/dl.
