What is the normal blood sugar level for a person? This is the most accurate way to measure blood sugar

Medical research has found that under correct circumstances, a person's fasting blood sugar level is between 3.9-6.1. One hour after eating, blood sugar levels will rise to 6.7-9.4, and it will take three hours to return to the correct value. Therefore, it is incorrect to measure blood sugar after a meal. To get a correct result, please follow your doctor's instructions.

1. Normal blood sugar level

We all talk about high blood sugar, so what is the standard for high blood sugar? What is the normal blood sugar level for a person? The fasting blood sugar level of a normal person is generally 3.9-6.1, which is the whole blood blood sugar value. The plasma blood sugar value will be relatively higher, at 3.9-6.9. When the fasting whole blood glucose is higher than 6.7, the plasma glucose is higher than 7.8, and both repeated measurements are greater than this value, it can be considered diabetes. One hour after a normal person eats, blood sugar levels rise to 6.7-9.4, and will not exceed 11.1 at most. Two hours later, blood sugar levels drop to below 7.8, and return to normal in three hours.

In addition to normal diabetic patients, who are mainly middle-aged and elderly people, there is also a type of diabetes called gestational diabetes. So what should be the normal blood sugar level for pregnant women?

Generally, the fasting blood sugar level of expectant mothers will not exceed 5.1. Even one hour after a meal, it should not exceed 10, and two hours after a meal, it should not exceed 8.5. Only when this standard is reached can it be considered a normal level.

2. Why should we measure blood sugar two hours after a meal?

First, some patients have normal blood sugar levels when fasting, but very high levels after meals. This is more common in patients with type 2 diabetes. If only fasting blood sugar is measured, these patients will be missed. There are also some people who are in a critical state of diabetes, and their blood sugar levels at this time will be higher than normal people. If the blood sugar level is between 7.8-11.1 at this time, further examination is needed to get a confirmed diagnosis; secondly, the blood sugar level two hours after a meal can also reflect whether the hypoglycemic drugs used by the patient are reasonable. At the same time, this value will not affect the patient's medication or injections.
