What is the blood sugar range for adults

As people's living standards improve, more and more people are suffering from affluence diseases such as high blood sugar and high blood lipids. Blood sugar is medically known as diabetes, which is a chronic endocrine disease that is usually incurable and can only be controlled through medication and diet. For many diabetic patients, they pay attention to their blood sugar range every day, so a simple instrument like blood sugar tester is very common in people's homes, and everyone can easily measure their blood sugar value, but for an adult, it is very necessary to understand the blood sugar range value. Let us take a detailed look at the normal values ​​of blood sugar in different periods.

1. Normal fasting blood sugar level standard (latest in 2018)

Generally, the fasting whole blood glucose level is 3.9-6.1 mmol/L (70-110 mg/dL), and the plasma glucose level is 3.9-6.9 mmol/L (70-125 mg/dL).

The following are some of the conditions that can be used to diagnose diabetes:

1. Fasting whole blood glucose ≥6.7 mmol/L (120 mg/dL) and plasma glucose ≥7.8 mmol/L (140 mg/dL), repeated measurements twice can be diagnosed as diabetes.

2. When the fasting whole blood glucose level is above 5.6 mmol/L (100 mg/dL) and the plasma glucose level is above 6.4 mmol/L (115 mg/dL), a glucose tolerance test should be performed.

3. When fasting whole blood glucose exceeds 11.1 mmol/L (200 mg/dL), it means that insulin secretion is very little or absent. Therefore, when fasting blood sugar is significantly elevated, diabetes can be diagnosed without the need for other tests.

2. Normal blood sugar levels for pregnant women

1. Pregnant women should not exceed 5.1mmol/L on an empty stomach

2. One hour after a meal for pregnant women: The blood sugar level one hour after a meal is generally used to detect diabetes in pregnant women. Authoritative data show that the normal blood sugar level for pregnant women should not exceed 10.0mmol/L one hour after a meal.

3. 2 hours after a meal for pregnant women: The normal blood sugar level after a meal is generally not allowed to exceed 11.1mmol/L, and the normal blood sugar level for pregnant women 2 hours after a meal is not allowed to exceed 8.5mmol/L.

3. Prediabetes diagnosis can be divided into three specific situations

1. First, fasting blood sugar is normal, and postprandial blood sugar is between 7.8mmol/L and 11.1mmol/L, which is called IGT (Impaired Glucose Tolerance);

2. The second is that the fasting blood sugar is between 6.1mmol/L and 7.0mmol/L, which is called IFG (impaired fasting blood sugar);

3. The third is that both the first and second types of IGT and IFG exist.

Experts say: "The first case (IGT) accounts for 70% to 80% of the total. It is important to note that the value of 7.8mmol/L is the upper limit of normal blood sugar two hours after a meal. Once blood sugar exceeds this value, it can be diagnosed as prediabetes or diabetes. People whose blood sugar is slightly higher than normal should go to the hospital for a detailed examination as soon as possible. Even if they are diagnosed as "prediabetes patients", their blood sugar levels have a chance to drop naturally by controlling their diet and weight."
