how much blood glucose is normal on an empty stomach
the normal value of fasting blood glucose is one of the commonly used indicators to judge whether the blood glucose concentration in the human body is normal 1、 So what is the normal value of fasting blood glucose? Generally, the blood glucose of fasting whole blood is 3.9 ~ 6.1 mmol / L, and the plasma blood glucose is 3.9 ~ 6.9 mmol / L. For pregnant mothers, the normal value of fasting blood glucose is 3.1-5.6mmol/l.
fasting blood glucose (GLU) refers to the blood taken before breakfast, after the fasting overnight (at least 8~10 hours without any food or drinking). The blood glucose level determined is the most commonly used indicator of diabetes, which reflects the islet &beta. Cell function generally represents the secretion function of basic insulin. The fasting blood glucose of normal subjects was 3.89 ~ 6.1mmol/l; If it is greater than 6.1mmol/l and less than 7.0mmol/l, fasting blood glucose is damaged; If two fasting blood glucose is greater than or equal to 7.0mmol/L, consider diabetes. It is recommended to recheck fasting blood glucose and glucose tolerance test. In addition, it is stipulated that the normal value of fasting blood glucose of pregnant women is 3.1-5.6mmol/l.
clinically, the blood glucose refers specifically to the glucose in the blood. The whole day blood glucose content of each individual will fluctuate with food, activity and so on. Generally, the blood glucose level is constant on an empty stomach. In clinical detection, glucose oxidase method can specifically measure the real blood glucose concentration. Blood glucose concentration is regulated by nervous system and hormones and remains relatively stable. When these adjustments lose their original relative balance, hyperglycemia or hypoglycemia occurs.
normal value of blood glucose 2 hours after meal
because the glucose content in the blood will increase due to the decomposition, synthesis and transformation of fat, protein, sugar and other substances in the food just after eating. Therefore, if the postprandial blood glucose concentration will rise, it is a normal phenomenon and there is no need to worry too much. However, if the blood glucose concentration rises beyond the normal range, you should go to the hospital for medical treatment. Especially for pregnant mothers to be, their blood glucose concentration should be controlled more strictly.
whether the blood glucose concentration of pregnant women is normal needs to be considered from two aspects: the normal value of fasting blood glucose of pregnant women and the normal value of postprandial blood glucose of pregnant women. For ordinary people, the normal value of fasting blood glucose can be maintained in the range of 3.9 ~ 6.1mmol/l. However, due to the particularity of pregnant women, the normal value of fasting blood glucose is strictly controlled. It is stipulated that the normal value of fasting blood glucose of pregnant women is 3.1-5.6mmol/l. The postprandial blood glucose depends on the number of hours after the meal. The postprandial blood glucose of one hour, two hours and three hours are different. The normal level of blood glucose is that the fasting of pregnant women does not exceed 5.1mmol/l and that of pregnant women does not exceed 10.0mmol/l one hour after meal. And the 1 hour postprandial blood glucose level is commonly used to detect diabetes in pregnant women. The normal blood glucose value of pregnant women 2 hours after meal shall not exceed 11.1mmol/l, while the normal blood glucose value of pregnant women 2 hours after meal shall not exceed 8.5mmol/l.
