What is blood sugar?

Blood sugar, short for serum glucose, generally refers to the concentration of glucose in blood.

Glucose is an important component of human body and an important energy source, which provides power for the normal operation of various tissues and organs. A normal human body needs a lot of sugar every day to provide energy and power for the normal operation of various tissues and organs. The acquisition of sugar in blood sugar mainly includes the sugar obtained by digesting food, and glycogen in the liver will be decomposed into glucose and enter the blood, becoming a part of blood sugar. When you are hungry, not only muscle glycogen will be broken down, but also some body fat and protein will be converted into glucose.

Blood sugar must be maintained at a certain level in order to maintain the needs of various organs and tissues in the body. The production and utilization of blood sugar in normal people are in a state of dynamic balance and remain at a relatively stable level, because the sources and ways of blood sugar are roughly the same. Too high or too low blood sugar will seriously affect your health. The latest Clinical Guidelines for the Prevention and Treatment of Type 2 Diabetes in the Elderly in China (2022 Edition) (hereinafter referred to as the New Guidelines) was released in June 2022. The new guide explains the diagnosis and classification of diabetes in the elderly, and points out that the diagnostic criteria of diabetes are not affected by age. Therefore, no matter how old you are, as long as the fasting blood glucose exceeds the range of 3.9~6. 1mmol/L, you can identify it as abnormal blood glucose, in which the fasting blood glucose is ≥7mmol/L and the random blood glucose is ≥1.1mmol/L, and you can diagnose diabetes.

With the continuous improvement of people's living standards in China, the number of people with abnormal blood sugar is also expanding. According to the data of global diabetes map, in the past 10 years (201/year ~202 1 year), the number of diabetic patients in China increased from 90 million to1400,000, an increase of 56%, including about 72.83 million. Although the growth rate of diabetes in China will tend to decline, the total number of patients will increase to 6543.8+0.64 billion in 2030 and 6543.8+0.75 billion in 2045, which has reached a level that cannot be ignored. Once diabetes is diagnosed, oral medication or insulin should be given under the guidance of a doctor on the basis of maintaining a good diet and exercise, combined with the patient's own situation, such as weight, exercise, fasting and postprandial blood sugar, complications, etc. In addition to the necessary medical treatment and maintaining good living habits, it is also important to do a good job in daily blood sugar management. It is suggested that you can prepare a home blood glucose meter according to your own situation, such as Sannuo blood glucose meter, to measure blood glucose regularly. Blood sugar level is related to everyone's life, health and safety. I hope everyone can pay attention to it, always pay attention to their blood sugar levels, and prevent problems before they happen.
