A fasting blood sugar of 5.0 mmol/L is usually not considered high, and this value falls within the normal range. Generally speaking, the normal range of blood glucose in a normal person during fasting is 3.9 to 6.1 mmol/L, while fasting blood glucose 5.0 mmol/L does not exceed the normal value, therefore, it is not considered high. In the case of pregnant women, a fasting blood glucose of 3.1 to 5.1 mmol/L is normal, so if a pregnant woman has a fasting blood glucose of 5.0 mmol/L, it is not considered high, and is a normal value. Although fasting blood glucose 5.0mmol/L is not high, but daily should also rationalize the arrangement of diet, eat more healthier food, such as high protein, high vitamin eggs, milk, chicken, apples, green vegetables and other foods, and with the exercise, to ensure that the body is healthy. Seek medical attention when you notice abnormal fasting blood glucose levels.
