Pregnant women with high blood glucose can control their blood glucose within the normal range through strict diet and exercise therapy; if the blood glucose is still poorly controlled by simple diet and exercise therapy, they can follow the doctor’s instructions to inject insulin for treatment. Pregnant women with high blood glucose should try to choose a low sugar, low salt and low fat diet, eat more fresh vegetables and fruits with low sugar content, avoid high sugar and fried foods, and at the same time, choose aerobic exercise that is acceptable to them, such as slow walking and swimming. Most patients can control their blood glucose within the normal range through strict diet and exercise therapy. However, those who are not well controlled by diet and exercise alone may be treated with insulin injections under the guidance of a doctor. It is recommended to monitor blood glucose, blood pressure, kidney function and fetal growth throughout the pregnancy and to seek medical attention if there is any discomfort.
