Blood sugar refers to the glucose in the blood, which is the body's main source of energy**. Blood sugar is essential for maintaining the normal physiological functions of the human body because it is involved in biological processes such as cell metabolism, nerve conduction, immune function, and more. However, abnormal blood sugar levels can cause various health problems, including diabetes, low blood sugar, and more.
Under normal physiological conditions, blood sugar levels are affected by a variety of factors, including diet, exercise, medications, etc. When the body ingests food, blood sugar levels rise, which stimulates insulin secretion and promotes blood sugar to enter cells for metabolism.
During exercise or fasting, blood sugar levels drop, which stimulates glucagon secretion and promotes the release of glucose from the liver to maintain blood sugar levels.
However, in some cases, blood sugar levels may be abnormally high or low. For example, people with diabetes may have elevated blood sugar due to insufficient insulin secretion or an inadequate response of tissue cells to insulin. Hypoglycemia can be caused by a drop in blood sugar levels due to not eating for a long time, exercising too much, and using drugs inappropriately.
For people with diabetes, it is very important to control blood sugar levels. With a sensible diet, exercise, and medications**, blood sugar levels can be effectively controlled and the risk of complications can be reduced. At the same time, regular monitoring of blood sugar is also necessary, which can help patients detect abnormalities in time and take corresponding measures.
Blood sugar refers to the glucose in the blood, which is the main source of energy in the body. However, if your blood sugar is too high or too low, it can have a negative impact on your health. Therefore, it is very important to know the normal range of blood sugar.
In fact, this new standard is not a simple numerical range, but a classification based on the characteristics of different groups of people. For example, for the average adult, the normal fasting blood sugar should be at 39~5.5mmol l;
And for pregnant women, the normal value of fasting blood sugar should be 33~5.1 mmol l. In addition, for special groups such as the elderly, obese people, and pre-diabetic people, the criteria for blood sugar are also different.
First of all, we need to know about our physical condition and family medical history. If you have a family with a chronic disease such as diabetes, then we also need to pay more attention to our blood sugar levels.
Secondly, we need to have regular physical examinations and blood glucose tests in order to detect abnormal blood sugar in time. In addition, we also need to pay attention to our diet and lifestyle, avoid unhealthy food intake such as high sugar, high fat, and high salt, and maintain proper exercise and rest.
At first, you may feel thirsty. This is because high blood sugar can lead to dehydration in the body, which can make the population thirsty. In addition, high blood sugar can also affect the function of the kidneys, leading to an increase in urine output, which can further exacerbate the feeling of thirst.
In addition to this, high blood sugar can also lead to fatigue and feelings of weakness. This is because high blood sugar affects the body's energy metabolism, making it impossible for the body to get enough energy to support daily activities. This feeling of fatigue and weakness may be more pronounced in the morning when you wake up, or worse after exercise.
In addition, high blood sugar may also cause vision problems. High blood sugar can cause the eyeball to become deformed, which can affect vision. This can make your vision blurry or double vision. If you find yourself with this problem, you should seek medical attention promptly.
In addition, high blood sugar can also cause numbness or tingling in the hands and feet. This is because high blood sugar can affect the function of the nervous system, making the hands and feet feel abnormal. This numbness or tingling may be worse at night or more pronounced in cold weather.
Finally, high blood sugar can also cause infections and poor wound healing. High blood sugar can make the immune system less functional, making the body susceptible to infections. At the same time, high blood sugar can also affect the speed of wound healing, making it difficult for the wound to heal. Therefore, if you find yourself with any of the above symptoms, you should seek medical attention and have relevant tests carried out.
First of all, make sure that your fingers are clean and dry. Hands should be washed and dried before measuring blood glucose to avoid bacteria and moisture on your fingers affecting the accuracy of the reading. If there is dirt, dust, or grease on your fingers, they can contaminate the blood glucose test strips, resulting in inaccurate readings.
Secondly, prick the finger correctly. When using a blood glucose meter, prick your finger with a clean needle and make sure that the puncture is of the right depth. If the puncture is not deep enough, it may result in blood not being able to flow out;If the puncture is too deep, it may cause pain and an increased risk of infection.
Third, use blood glucose test strips correctly. Blood glucose test strips should be used correctly as instructed on the instructions. If used incorrectly, it can result in inaccurate readings. In addition, blood glucose test strips also have a certain shelf life, and expired test strips may cause inaccurate readings.
Fourth, pay attention to the time when your blood sugar is measured. Diabetics should arrange a reasonable time to measure their blood sugar according to their doctor's advice and their own condition. In general, fasting blood glucose, postprandial blood glucose, and bedtime blood glucose are important time points for diabetics to pay attention to.
Finally, it is important to interpret the blood glucose results correctly. Blood glucose readings should be compared to the target value recommended by your doctor and adjusted according to your doctor's recommendations. If your blood sugar readings are abnormally high or abnormally low, you should seek immediate medical attention.
Measuring blood sugar at home may seem simple, but there are many things to be aware of. Only by mastering these tips and methods correctly can you get accurate blood sugar readings and better manage your condition.
