blood glucose level after eating of 212
ANSWER: Hi, Normally, there is an elevation in the blood glucose level after eating. For that reason, there exists a precise schedule for the blood glucose values before and after eating. For example, if you get up at 7:30, your glucose level is going to in normal ranges 70-100mg/dl. If you eat something at 8:00, normally, your glucose will rise to values of 200-250mg/dl in a period of 2 hours after having a meal. Of course, there are individual differences in these values and lot of test which have to be estimated in purpose to confirm or reject diabetes as diagnosis. Therefore, when you blood glucose level is low, certain hormones like glucagon and adrenalin are increasing it by stimulating the hydrolysis of glycogen (polymer of glucose stored mainly in the liver). If your blood glucose is high, the insulin secretion is increased consequently. The bad thing in here is that insulin is the only hormone which is reducing the amount of blood sugar in plasma. Furthermore, the organism requires time for the insulin secretion and the insulin needs time to lower your blood glucose level. That is the reason why you have an elevation of the blood glucose in a period of two hours after having a meal. That is also the reason why you are not supposed to eat before the blood test. If there was some kind of abnormality in your glucose metabolism, the blood sugar in 7:30 will be about 200-250 and, after having a meal it is going to be 300 mg/dl. In purpose to be sure that you are not having diabetes, there is a test for impaired glucose tolerance. This test is providing you a diagram of your blood glucose values during the whole day. This will make you see that everything is ok with your glucose metabolism. This test is estimated in every hospital by every doctor who is endocrinologist. Hope it helped! Dr.Alba |
