What is the normal blood sugar level after a meal?

Older people are afraid of having high blood sugar because it can trigger a series of symptoms, such as dizziness, nausea, etc. People's living standards are getting better and better, and they have more money to buy more delicious food. However, if some things are eaten too much and blood sugar suddenly rises, it can also be harmful to human health. So what is the normal blood sugar level after a meal? In fact, there are different standards, because when the human body just ingests sugar, the blood sugar level will be relatively high, but as time goes by, the blood sugar level will gradually drop.

For diabetic patients, sugar intake must be strictly controlled. Because I already have diabetes, if I don't control my diet, it is very likely that my sugar intake will exceed the standard, which will bring serious consequences to my body. Here are some references to normal blood sugar levels after meals, I hope they can help you.

Normal blood sugar level 1 hour after a meal: The normal value is 6.7-9.4 mmol/L in the first hour after taking sugar. Normal blood sugar level 2 hours after a meal: blood sugar level ≤7.8 mmol/L in the second hour. Normal value of blood sugar after meal: normal value for 3 hours: returns to normal after the third hour, and each urine sugar is negative.

The normal value of fasting blood glucose (FPG) is 3.9-6.1mmol/L; 6.1-7mmol/L is abnormal fasting blood glucose (IFG); the normal value of blood glucose 2 hours after a meal is 7.8-11.1mmol/L for impaired glucose tolerance (IGT); fasting blood glucose ≥7.0mmol/L or 2-hour postprandial blood glucose (P2hPG) ≥11.1mmol/L for diabetes. When suffering from diabetes, fasting blood sugar is higher than normal, and blood sugar 2 hours after taking sugar is ≥11.1 mmol/L.

Blood sugar (GLU): Blood sugar clinically refers to the glucose in the blood. IFG and IGT are the intermediate transition stages between normal people and diabetic patients. Such people are the high-risk group and reserve force for diabetes and should be taken seriously and intervened early.

A 2-hour post-meal blood sugar test is actually a simplified glucose tolerance test. Because this method requires fewer blood draws than the oral glucose test, is simple and easy to perform, and is easily accepted by patients, it is the most commonly used method in clinical practice to screen and detect diabetic patients with normal fasting blood sugar.

Measuring blood sugar 2 hours after a meal has two meanings. One is for diagnosis, and the other is to observe the recovery of glucose tolerance, thereby reflecting the functional status of the pancreas. If after a period of treatment, fasting blood sugar has returned to normal, but postprandial blood sugar is still high, it often indicates that the patient's glucose tolerance is still poor and insulin secretion is still delayed. If fasting blood sugar is normal and postprandial blood sugar is also normal, it means that the patient has better glucose tolerance and improved pancreatic islet function.

The above is the reference of relevant data for everyone. If you don’t have an instrument to measure blood pressure, it is best to buy an instrument to measure blood sugar, so that you can know in time whether your blood sugar is within normal values. Neither high nor low blood sugar is a good sign, so older people should pay more attention to this aspect. Otherwise, if something bad happens, they may have to be hospitalized for a long time.
