The normal range of fasting blood glucose of pregnant women should be less than 5.1mmol/L. When fasting blood glucose of 5.4mmol/L is on the high side, it can be lowered through dietary control, proper exercise and medication. 1. Dietary control: control the total calorie intake per day, avoid eating high sugar and high fat food, such as cake, milk tea, fat meat, fried food and so on. 2. Appropriate exercise: It can help to increase insulin sensitivity. Low to moderate intensity aerobic exercise, such as walking, is generally recommended. 3. Medication: If you cannot control your blood sugar well through diet control and proper exercise, you need to consider using insulin and other hypoglycemic drugs. Pregnant women with fasting blood glucose of 5.4mmol/L are advised to go to the hospital and ask the doctor to make a judgment and formulate an individualized treatment plan.
