Introduction
Under normal circumstances, the range of normal blood glucose levels is mainly divided into fasting blood glucose and postprandial blood glucose. The normal value for fasting blood glucose should be below 6.1 mmol/L, while the normal value for blood glucose two hours after a meal should be below 7.8 mmol/L. In daily life, maintaining healthy eating habits, engaging in moderate exercise, and following a regular作息 (作息 should be translated as "routine" or "作息 time," but since it's in the original text, it's kept as is) can help maintain normal blood glucose levels.
Generally, the normal range of blood glucose levels is mainly divided into fasting blood glucose and postprandial blood glucose. The normal fasting blood glucose level should be below 6.1 mmol/L, while the normal value for blood glucose two hours after a meal should be below 7.8 mmol/L. A detailed explanation is as follows:
Normal blood glucose refers to the concentration of glucose in the blood maintained within a certain range when the body is in a fasting or postprandial state. Fasting blood glucose refers to the concentration of glucose in the blood after at least 8 hours without eating, which typically should be below 6.1 mmol/L. If there are no other diabetes-related symptoms, such as frequent urination or excessive thirst, blood glucose is generally considered normal.
Postprandial blood glucose refers to the concentration of glucose in the blood within a certain time after eating. After eating, carbohydrates in food are broken down into glucose, which enters the bloodstream, causing blood glucose levels to rise. Two hours after a meal, blood glucose levels should gradually return to near fasting levels, generally below 7.8 mmol/L.
In daily life, maintaining healthy eating habits, moderate exercise, and regular sleep patterns can help maintain normal blood glucose levels.
