When is the best time to test fasting blood sugar?

Skipping meals between 8 and 14 hours is fasting blood glucose.

At present, diabetic patients now have no specific drugs**, and can only use insulin and hypoglycemic drugs to control blood sugar. Many diabetic patients do not pay attention to their diet and do not control their blood sugar during the ** period, resulting in rising blood sugar, which affects their health. When is the best time to test?

Generally, the fasting blood glucose value of a normal person is, if the fasting blood glucose value is, the diagnosis of diabetes mellitus, if the fasting blood glucose value is significantly increased only occasionally, or if the blood sugar value rises significantly after two hours after a meal, it can also be diagnosed as diabetes.

In the case of fasting in diabetic patients, the fasting blood glucose level is maintained at normal if the elderly have diabetes and other underlying diseases. Generally, young people have diabetes, and the range of blood sugar control will be better, but due to the older age of the elderly and the more underlying diseases, blood sugar control is relatively unstable.

The best time to test blood sugar on an empty stomach is between 6:00 and 8:00 in the morning, you must be fasting for 8 hours to 12 hours, do not eat any food, you can drink some warm water when testing blood sugar, you must not drink sugar water, so as not to affect the blood sugar test results, and the fasting blood glucose value can indirectly assess the basal insulin secretion.

The fasting blood glucose test is the most accurate time period between 6:00 and 8:00 in the morning, because the hormone influence at this time is relatively small, the fasting time is relatively normal, the detection time is too early, the test result will be high, the detection time is too late, it is easy to have hypoglycemic reaction, and the test result is easy to be low.

Fasting blood glucose testing is very critical, and in order to detect blood glucose values more accurately, it cannot be done in advance or delayed, and the blood glucose values that are tested in advance or postponed are inaccurate. Diabetic patients should pay attention to controlling their diet, reducing the intake of sweets, reducing the intake of fat, eating a light diet, eating more vegetables and fruits, exercising appropriately, enhancing physical fitness, improving immunity, and actively controlling blood sugar.

It is generally better to test blood sugar on an empty stomach for more than 8 hours.

Fasting blood glucose is a blood glucose level measured overnight, fasting for at least 8 hours, and waking up in the morning. Diabetic patients should also be monitored for postprandial blood glucose fluctuations. Normal fasting blood glucose is between to, and blood glucose < 2 hours after meals.

Fasting blood glucose does not refer to the blood sugar level before a meal, and it is best to measure the blood sugar level after waking up in the morning. This is due to the fact that when the body starts to move after a person wakes up, hormone levels also change, resulting in differences in blood glucose levels monitored each day.

Blood sugar measurement generally requires that you cannot eat after 10 o'clock the night before, and you can measure your blood sugar after waking up at about 8 o'clock the next day, and it is best not to drink water or a small amount of water during this period.

If you find any abnormalities in your blood sugar, it is recommended to measure your blood sugar several times, and if you feel unwell, seek medical attention as soon as possible, under the guidance of your doctor**.

Fasting blood glucose is generally considered normal when it is; It is best to test on an empty stomach for about 8 hours, for example, it can be done around 7 a.m. the next day.

It is normal, it is most appropriate to measure it before meals, and you need to pay attention to your physical condition.

Blood glucose is measured on an empty stomach and after meals.

Fasting refers to checking your blood sugar in the morning when you wake up without food after getting enough sleep at night.

After a meal is when your blood sugar is checked two hours after you have eaten food.

Generally, doctors will recommend two tests to be completed in the morning, i.e. one test on an empty stomach, then go to breakfast, and take another test two hours later.

Hello, fasting blood glucose value actually refers to food that has not consumed any calories in 8 hours (drinking water does not count). So fasting is generally in the morning.

There are two best times to measure blood glucose: fasting blood glucose (the normal range is two-hour postprandial blood glucose values. Two hours after a meal refers to the normal range of blood sugar values (2 hours after eating the first bite of food).

If you have any questions, please continue to ask, I hope it will be helpful to you.

Fasting is of course early in the morning

It is better to check fasting at 6 a.m., when endogenous glycemic hormone levels are still low.

However, it needs to be determined by the examination method, if it is peripheral blood glucose to be checked with a rapid blood glucose meter, it is better at 6 o'clock in the morning; If the venous blood glucose is measured by a biochemical instrument, it is also accurate if the blood glucose is checked or to be checked by the hospital laboratory after the blood is drawn, that is, after centrifugation.

However, if the blood is not centrifuged after the blood is drawn, and then sent to the laboratory department after normal working hours, and then the laboratory department collects the blood samples from the whole hospital for centrifugal examination, the result will be lower than the normal value.

Well, the best time, this question is right, there are several stages, when should I choose to measure blood sugar?

When is the best time to measure blood sugar for diabetics? Now I would like to tell you as a member of the Hunan Military Region Hospital: This is a common question asked by many patients.

It is best to measure blood sugar without external interference, and many diabetic patients go to the hospital for examination, and when they are delayed for a long time on the road, the body consumes energy, and the blood sugar at this time cannot be used as the only basis for blood sugar. So why should patients measure their blood sugar?

Ideally, blood sugar should be controlled before and after meals, physical activity and sleep time, since only a single blood glucose measurement can only be used to monitor blood glucose for a period of time. Therefore, it is difficult to measure accurately.

According to the analysis of diabetes experts: according to the law of changes in human blood sugar, the blood sugar value is the lowest at 3 a.m. (generally should not be lower), and then the blood sugar gradually rises. Normal people have normal insulin secretion, and the blood sugar value can be controlled within the normal range, while diabetic patients have low insulin levels, and their blood sugar is significantly affected by insulin resistance hormones, and the blood sugar value will gradually increase.

Therefore, it is best for patients to measure fasting blood sugar at 6 o'clock in the morning to 8 o'clock in the morning, and the blood sugar value will be higher and higher after 8 o'clock, which cannot truly reflect the best effect. Fasting blood sugar must be fasted for 8 hours, do not take hypoglycemic drugs before blood collection, do not exercise, some patients rush all the way to the hospital to measure venous blood and finger blood, the results of the sample test are often different, after exercise after a period of rest can be measured.

For most diabetic patients, the daily visit to the hospital to monitor abnormal blood sugar is only a manifestation of the situation at that time, but the time of blood glucose monitoring in the hospital is not very clear about the blood sugar situation. However, the best way to do this is to use a blood glucose meter in your own home.

Fasting blood glucose generally refers to blood collected before breakfast after fasting for at least 8-10 hours overnight, except for drinking water.

8-10 hours without food (except water) is fine.

When you wake up in the morning, don't eat.

Yes, do you have other symptoms of diabetes, such as fatigue, polydipsia, polyuria, polyphagia, etc. Only one fasting blood glucose cannot diagnose diabetes.

Time points for monitoring blood glucose include:

Fasting blood glucose: refers to the blood glucose value measured by blood collection before breakfast after fasting overnight (fasting for at least 8-10 hours, except drinking water), which generally represents the secretion function of basal insulin. When blood sugar levels are high, fasting blood sugar levels are the first thing to focus on.

Preprandial blood glucose: The blood sugar measured on an empty stomach before breakfast, lunch and dinner. People at risk of hypoglycemia (older adults, those with good glycemic control) should have their preprandial blood glucose measured.

Postprandial blood glucose: The blood sugar measured after breakfast, lunch and dinner is measured from the first bite of food. Patients taking hypoglycemic drugs or insulin injections should take hypoglycemic drugs or insulin injections as usual.

It is most valuable to monitor blood glucose 2 hours after a meal, which can reflect the reserve function of pancreatic B cells, and observe whether the intake and hypoglycemic drugs are appropriate. 2-hour postprandial blood glucose monitoring is suitable for those who have well-controlled fasting blood glucose but still cannot achieve the ** target.

1:00-2:00 p.m. blood glucose: used to monitor and identify nocturnal hypoglycemia. It is used for those who have reached the target of insulin ** and the fasting blood sugar is still high.

1 hour before meals 1 hour after meals.

Fasting blood glucose is measured after at least 8 hours of fasting and is normal below millimoles per liter (mmol L); Postprandial blood glucose can be measured after a meal or with an oral glucose tolerance test, and the normal value is less than 10 millimoles per liter (mmol L) 1 hour after a meal and less than millimoles per liter (mmol L) 2 hours after a meal

Analysis: Hello, fasting blood sugar is normal if it is less than it, and diabetes if it is greater than it.

Suggestions: In order to prevent blood sugar elevation, it is recommended to pay attention to the usual diet, low-sugar and low-fat diet, minimize the intake of pasta, eat more vegetables, strengthen physical exercise, maintain a good attitude, and monitor blood sugar regularly.
