Sleepiness after meals, low blood sugar before meals, and hunger when full cannot be ignored. 6 types of people should pay attention to the risk of diabetes
Lao Li is an old driver. He is just 42 years old this year. Since this year, he feels that his physical strength cannot keep up, especially after every meal, he will be very sleepy. Then I drove, but now I always have to take a break, otherwise it is easy to be dangerous.
The company asked Lao Li to check to see if there was any problem. As a result, he did not expect to check the fasting blood sugar of 7.1mmol/L. The doctor told him that he might already be diabetic, and asked him to take a glucose tolerance test to analyze the specific reasons.
It is estimated that many middle-aged and elderly people will be particularly sleepy after meals, and will be hungry soon after eating. Many people also have their own perceptions that blood flows into the gastrointestinal tract for absorption after eating, which leads to a decrease in cerebral blood flow and drowsiness. But have you noticed? I use middle-aged and elderly people. This is because young people are less likely to have this kind of situation, and the reason is related to blood sugar. This may be an alarm issued by the human body for improper diet or abnormal blood sugar. Then, why is blood sugar? Will it make you sleepy? How to avoid abnormal blood sugar?
Drowsiness after meals that cannot be ignored
As for the problem of sleepiness after a meal, many people think that it is because the blood concentrates in the stomach and the brain and ischemia and hypoxia in the brain, but in fact, this statement has not been proven medically, and Chinese people also have the habit of taking a lunch break. This also covers up the problem on the one hand. In fact, the main reason for easy sleepiness after meals is related to the rapid rise and fluctuation of blood sugar.
According to statistics, one-third of people in China suffer from high blood sugar, and these people are mainly middle-aged and elderly. Fast, so there is less drowsiness after a meal. In the case of long-term hyperglycemia, the human body will gradually develop severe insulin resistance, and then the pancreas will be overburdened, β cells will be damaged, and type 2 diabetes will gradually develop.
Therefore, frequent sleepiness after meals cannot be ignored.
Why does blood sugar change drastically?
Blood sugar is the level of glucose in human blood, which is mainly related to human eating. When people ingest food (mainly carbohydrates) into the stomach, the sugar is absorbed and decomposed into glucose, and the blood sugar of the human body will rise accordingly. At this time, insulin intervenes , the glucose will be moved to the cells and muscles for energy utilization and storage, and the blood sugar will return to the normal level at this time.
During this process, we will find that if we eat too much sugar or staple food, the glucose level that enters the blood after the food is digested and absorbed will also increase, especially when a large amount of fast intake is taken, the blood sugar will rise in a very short time. High, people are in a state of high blood sugar.
Hyperglycemia can cause various discomfort symptoms, such as dizziness, fatigue, sleepiness, general weakness, etc. In order to relieve hyperglycemia, the human body will arrange for the pancreas to secrete a large amount of insulin, resulting in hyperinsulinemia, which increases the burden on the pancreas. Hyperglycemia will also damage the beta cells of the pancreas, and the long-term pancreatic function will be greatly reduced, and more than 50% may enter the state of diabetes.
Besides being drowsy after a meal, what other signs of high blood sugar are worth noting?
There are two main points:
Hungry again soon after a meal
This is because, in the case of high blood sugar, the pancreas secretes more insulin, and hyperinsulinemia will then cause a rapid drop in blood sugar, which can easily lead to hypoglycemia. In this case, the human body will think that the intake of energy is not enough, which will make people feel hungry. , thus entering a vicious circle.
In addition, when a person enters the stage of diabetes, if the blood sugar is not well controlled, the excess sugar may be excreted through the kidneys. If the amount of food that was originally just right, suddenly lacks the blood sugar drop, there will also be hunger after meals, but the person will continue to lose weight. .
low blood sugar before meals
People with high blood sugar often have abnormal blood sugar regulation. Poor blood sugar control will lead to abnormal blood sugar fluctuations. The original blood sugar can be stable until after eating, but it may have started to drop rapidly before eating, and then hypoglycemia occurs.
If someone has the above three points, it basically means that the blood sugar control is poor, the blood sugar fluctuates greatly, or they are in high blood sugar condition for a long time.
What are the factors that affect blood sugar fluctuations?
In addition to normal diet, what other factors will affect blood sugar fluctuations? It is closely related to exercise, emotions, and living habits.
- Exercise
Exercise requires energy support. In addition to blood sugar, it may also require the glycogen stored in the body to be decomposed into glucose to provide energy. During this process, the blood sugar of the human body will fluctuate greatly, but if the blood sugar of the human body is regulated normally, then this fluctuation is It is relatively small, and if blood sugar is not well controlled, or if you are diabetic, strenuous or a lot of exercise may cause blood sugar to fluctuate, which is prone to danger.
Therefore, although exercise is beneficial for blood sugar control, it is mainly concentrated in general aerobic exercise, strenuous anaerobic exercise or a large amount of aerobic exercise, which may lead to hypoglycemia and be dangerous.
- Pressure
When the pressure is high, the endocrine of the human body will be adjusted, and the corresponding hormone secretion will lead to the increase of blood sugar and blood pressure, so that people can have the strength to fight against the pressure and have a greater tolerance. When stressed, insulin secretion helps blood sugar return to normal.
Originally normal regulation, if you are in a state of high stress for a long time, then the blood sugar will fluctuate up and down, which will have adverse effects on people.
- Sleep
Sleep actually has a great impact on the human body. On the one hand, it can regulate the nerves, and on the other hand, it can also regulate the endocrine. Poor sleep makes the sympathetic nervous system active, adrenaline secretion increases, and blood sugar rises. Long-term staying up late or poor sleep quality increases the risk of metabolic syndrome and diabetes.
In addition, too little or too much sleep can also cause blood sugar fluctuations.
- Additional Eating Behaviors
Extra-eating behaviors are mainly concentrated in the intake of food outside the normal diet, especially the consumption of processed food or sugar-sweetened beverages. These foods are mostly foods that contain a lot of sugar, fat and salt, which are easily absorbed. , it can also make blood sugar fluctuate wildly.
The effect of blood sugar fluctuations on the human body
The fluctuation of blood sugar is not easy to observe, but there are still signs of severe fluctuations. If you often want to sleep after eating, your blood sugar is low before meals, or you are hungry soon after eating, you may have large blood sugar fluctuations in your body. .
Too much blood sugar fluctuation will cause oxidation and inflammation in the blood vessels of the human body, especially the capillaries, which will lead to blood vessel damage, thereby increasing the risk of cardiovascular disease, kidney disease, eye disease, and neuropathy. Sometimes, although it has not yet reached the stage of diabetes, However, if the human body is more sensitive to changes in blood sugar, some complications may occur.
In addition, although blood sugar fluctuations are inevitable, we can reduce the amplitude of blood sugar fluctuations and shorten the time of blood sugar fluctuations in various ways, thereby reducing the harm to the human body.
Who needs to pay attention to blood sugar as soon as possible?
In fact, no matter the age, anyone may have the problem of high blood sugar. In addition, the incidence of the disease is getting younger and younger. Therefore, it is generally believed that people over the age of 40 should pay attention to it. Now it should be adjusted. Any age group People who have pharmaceuticals that meet one of the following are recommended to pay more attention to blood sugar:
Overweight: BMI (Body Mass Index) greater than or equal to 24
Waist circumference is too high: over 90 cm for boys; over 80 cm for girls
Medical history: Family history of diabetes
Living Environment: Long-term stressful situations
Exercise: no regular exercise or too little exercise
Lifestyle habits: poor long-term sleep, poor sleep quality, less sleep time
How much blood sugar is normal? How do I know my current blood sugar status?
Although blood sugar will fluctuate, due to the adjustment of insulin, normal people will fluctuate between 3.9-7.8mmol/L about 90% of the time, especially the fluctuation range before and after meals is generally less than 3.33mmol/L. If If you want to know your blood sugar situation, you can use a home blood sugar meter, or go to the hospital to check fasting blood sugar or glucose tolerance test. If you have the conditions, you can use dynamic blood sugar monitoring to understand the blood sugar trend in a day, especially the impact of diet and exercise on blood sugar. Happening.
Many people think that high blood sugar and diabetes are congenital heredity, but in fact, more than 90% of diabetics are caused by the day after tomorrow, which is related to life, diet, and exercise habits, so even normal people should pay attention to their own blood sugar. , Relevant tests can be carried out during the annual physical examination, and blood sugar control can be done well, so as to stay away from the influence of chronic diseases.
