Sugar friends often ask: Doctor, fasting blood sugar or postprandial blood sugar, which is more important?
German studies have shown that compared with fasting blood glucose targets,Postprandial glycemic glycemic targets are more conducive to glycosylated hemoglobin targets
When only fasting blood glucose is reached, 36% of patients still fail to meet the glycosylated hemoglobin standard. When postprandial glycemic glycemic glycemic targets are reached, only 6% of patients do not meet glycosylated hemoglobin targets.
Fasting blood glucose control is necessary but usually not sufficient to achieve the goal of glycosylated hemoglobin less than 7%. Postprandial blood glucose control is essential to achieve glycosylated hemoglobin targets.
In general, whether it is fasting blood sugar or postprandial blood sugar, it is very important for sugar friends!
Monitor your blood sugar and stay on top of it throughout the day
Fasting blood glucose refers to the blood sugar in the early morning fasting state after 8-12 hours of not eating. Fasting blood glucose reflects the level of basal insulin secretion of sugar friends.
For sugar friends who have been using hypoglycemic drugs for a long time, "fasting blood glucose" can also reflect whether the dosage of hypoglycemic drugs is appropriate for the first night.
If the fasting blood sugar is high, the blood sugar after the meal will naturally be high, resulting in high blood sugar throughout the day. Therefore, well-controlled fasting blood sugar is good for blood sugar control throughout the day.
Blood sugar is affected by a variety of factors, as there are fewer factors that affect blood sugar when measured on an empty stomach in the morning. Therefore, fasting blood sugar can reflect the real condition of sugar friends, and fasting blood sugar is especially important for sugar friends who have been using hypoglycemic drugs for a long time.
High postprandial blood sugar is associated with a high risk of complications
Eating and drinking can raise blood sugar, so blood sugar is usually higher after a meal than before a meal. However, the increase in blood sugar should not be too large, otherwise it will be high blood sugar after meals, which will increase the risk of complications of diabetes.
Postprandial blood glucose reflects the islet cell reserve function. That is, when we eat, the ability of the pancreatic islet cells of diabetics to secrete insulin under the action of food.
High blood sugar after a meal is more important than fasting blood sugar
Why? Blood sugar in diabetics tends to rise first after a meal, and then fasting blood sugar rises after a period of time.
If you do not pay attention to and do not monitor postprandial blood sugar, waiting until your fasting blood sugar is high, it means that your body has been in an environment of high postprandial blood sugar for a long time. This is also the reason why some diabetics have complications as soon as they are diagnosed with diabetes.
Causes of high fasting blood sugar and what to do
The Sumujie phenomenonSome sugar friends have the "Su Mujie phenomenon", that is, there is a hypoglycemic attack at night, which leads to a rebound increase in fasting blood sugar the next day. This can be confirmed by monitoring blood glucose at night (especially in the early morning).
If fasting hyperglycemia is caused by Su Mujie's phenomenon, it is necessary to appropriately reduce the dose of oral hypoglycemic drugs (or medium-acting insulin before bedtime) before dinner under the guidance of a doctor to avoid recurrence of hypoglycemia.
Insufficient dose
On the premise of excluding the phenomenon of Su Mujie, if the dose of the drug is insufficient, the dose of hypoglycemic drugs can be adjusted as appropriate under the guidance of doctors, or the hypoglycemic drugs can be adjusted to achieve fasting blood glucose.
The day before, eating too much
Eating too much for dinner and not exercising after dinner. This can lead to high blood sugar after dinner that can last until the next morning.
There is another reason, in order to prevent low blood sugar at night, sugar friends add meals before bedtime. Eating too much can lead to fasting hyperglycemia.
Insomnia or poor sleep quality
Insomnia at night, or being overly stressed, can also lead to high fasting blood sugar in the morning. So relax your mind, regulate your emotions, and relieve stress.
In short, both fasting and postprandial blood sugar are important. Be a qualified sugar friend and comprehensively control your blood sugar in order to better prevent complications.
