Now the living conditions have changed, the types of food and nutrition are more abundant, but the probability of the three high groups has increased, especially the diabetes, which is known as "rich and noble disease". With the continuous intake of high sugar food in the diet, the probability of the occurrence is much higher than before. Blood glucose is a nutrient that the brain needs. If it is deficient or excessive, there will be adverse effects on the body. Therefore, in physical examination, blood glucose needs to be checked every time.
Under normal circumstances, the body's blood glucose is in a relatively stable range, fasting blood glucose in 3.9-6.1mmol/l, if the blood glucose content is insufficient, then you are hypoglycemia, if it is beyond, then it is hyperglycemia or diabetes. When some people measure their blood glucose, they find that the glycemic index is between 7.5-8.5mmol/l, which is beyond the normal range, so they think they have diabetes. Is this really the case? Don't be too nervous, doctor.
People who often have physical examination in life know that most of the physical examination needs fasting, so as to more accurately understand the body value under normal circumstances, and the judgment of diabetes is the same. If you are in the state of fasting, blood sugar values continue to exceed the normal range, then you can judge the emergence of diabetes.
But it should be noted that not as long as the fasting blood glucose exceeds the normal range is diabetes, we should know that the blood glucose value will be affected by many factors, such as long-term fatigue, pregnancy, pregnancy and so on, which may affect the blood glucose value. Therefore, if the blood glucose value exceeds the normal range after a check, we can carry out multiple tests, if it is only occasionally exceeded, it is nothing It's related. Don't worry. If it continues to exceed the limit, it may be a symptom of diabetes and needs to be adjusted as soon as possible.
In fact, in the early stage of diabetes, in addition to the rise of blood sugar, there are also some physical abnormalities. If you can pay attention to it in time, you can control blood sugar as soon as possible, reduce body damage, especially the following three symptoms, you need to leave snacks.
1. Abnormal changes in mood
The blood glucose is the main nutrition that the brain needs before. If it exceeds, it is easy to affect the nerve abnormality, and the abnormal changes of nerve will also affect the normal function of internal organs, thus causing abnormal changes of emotion. If you find that in the recent time, the emotion has changed for no reason, it may be the performance of blood glucose exceeding, you should pay attention to it at ordinary times.
2. Sudden loss of vision or fatigue
Now there are so many electronic products in our life, people who look at mobile phones or computers every day are prone to eye fatigue, vision loss, etc. this situation is a normal physiological reaction, and appropriate rest can play a certain role in alleviating. But some people will have a sudden decline in vision and feel a blur in front of their eyes. If so, it may be the physical manifestation of excessive blood glucose. The main reason is the change of blood pressure caused by excessive blood glucose, which leads to insufficient blood supply around the eyes or retinal abnormalities.
3. Increased urination
Although sugar is an important nutrient in the body, if the content exceeds a lot, it will also affect the normal metabolism in the body. The most common manifestation is the increase of micturition frequency. This is because with the increase of blood glucose concentration, the filtration speed of glomerulus will be accelerated in order to maintain normal blood supply, so a large amount of water is produced, which is not enough Can be timely reabsorbed into the body, it will increase the content of urine in the bladder, which is the origin of increased urination.
After the blood sugar exceeds, in addition to the frequency of urination will increase, also prone to thirst, this is because the body's water is a lot of metabolism and out of the body, so "drink more, more urine" is the most common symptom of diabetic patients, usually need more attention.
If you have the above situations, then you need to pay attention to your blood sugar changes in time. Some people in life think that it will be very troublesome to check your blood sugar and go to the hospital all the time, so they have a home blood sugar measuring instrument to facilitate you to better understand your blood sugar. If you are a diabetic, you should pay more attention to your blood glucose changes, which can not only monitor your blood glucose in real time, but also facilitate the doctor to adjust the body condition and blood glucose value.
In short, only if the blood glucose test exceeds the limit, it is not necessarily diabetes. It may also be affected by other factors. It needs to be checked many times to be more accurate. At the same time, it is suggested that those who are ready to go for physical examination should keep their body shape normal before physical examination, so that they can understand the physical condition more accurately and conduct professional adjustment All right.
