Do you know what blood sugar is?

What is blood sugar?

Blood glucose usually refers to free glucose in the blood, which is the transport form of sugar in the blood. Measuring blood sugar means measuring the concentration of glucose in the blood.

So where does the glucose in the blood come from?

Blood sugar mainly comes from diet, especially carbohydrate-based foods, such as rice, noodles, steamed buns, rolls, bread, cakes, sucrose, brown sugar, honey, etc. These foods are converted into glucose and absorbed by the body.

What is the role of blood sugar on the human body?

The most basic unit of the human body is the cell, and the energy of the cell comes from glucose. Glucose is the only source of energy for brain cells and nerve cells. Just like a car needs gasoline to run, people must need glucose to be able to move.

So what is the normal blood sugar range?

Under normal circumstances, healthy people's blood sugar can be maintained within a relatively constant range both on an empty stomach and on a full stomach. The normal fasting blood glucose is 3.3~6.1mmol/L. Fasting blood glucose refers to no energy intake for more than 8 hours. Generally, patients do not eat after 8 pm and draw venous blood on an empty stomach in the morning. The normal range of blood sugar 2 hours after a meal is 3.3~7.8mmol/L, and the 2 hours starts from the time of eating.

When brain cells and muscle cells are short of energy supply, nausea, palpitation, dizziness, cold sweats, and even limb twitching may occur. In severe cases, death may occur. It can be seen that blood sugar must be maintained at a certain level to maintain the needs of various organs and tissues in the body.
