Is blood sugar of 8.2 normal after a meal? How to deal with it

People with high blood sugar generally suffer from diabetes, a lifelong disease that can be controlled with medication, and they can work and study like healthy people. Blood sugar levels are different at every moment, and the size of the fluctuation determines the severity of the diabetes. So, is a blood sugar level of 8.2 after a meal normal? How should it be handled?

1. According to the national epidemiological survey data from 2007 to 2008, nearly 150 million people are in the reserve force of diabetes - prediabetes. Prediabetes refers to a state in which blood sugar levels are between normal and diabetes. More than 70% of prediabetes patients have impaired glucose tolerance, with normal fasting blood sugar and only elevated postprandial blood sugar.

2. 7.8mmol/L is the upper limit of normal blood sugar value two hours after a meal. Once the postprandial blood sugar level exceeds this value, it can be diagnosed as prediabetes or diabetes. Even if fasting blood sugar is normal (less than 5.6mmol/L), if blood sugar exceeds 7.8mmol/L two hours after a meal, if it is less than 11.1mmol/L, it can be diagnosed as impaired glucose tolerance. If the blood sugar level is higher than 11.1mmol/L two hours after a meal, it means that you have entered the stage of diabetes.

3. For people with impaired glucose tolerance, lifestyle intervention can effectively reduce the risk of diabetes. That is to say, when postprandial blood sugar is found to be between 7.8-11.1mmol/L, lifestyle intervention can be used to lower blood sugar, thereby preventing oneself from developing diabetes. Lifestyle intervention mainly includes diet control and exercise. This includes ensuring a balanced diet, limiting total calorie and fat intake, limiting alcohol consumption, eating more vegetables and high-fiber foods, and engaging in regular and sustained physical exercise.

The specific goals are:

First, the body mass index (BMI) of obese or overweight people, that is, weight (kg)/height (㎡) reaches or approaches 24kg/m2, or the body weight is reduced by at least 5%-10%;

Second, reduce the total daily calorie intake by at least 400-500 kcal;

Third, saturated fatty acid intake should account for less than 30% of total fatty acid intake; Fourth, physical activity should be increased to 250-300 minutes/week.
