Pregnant women with high blood glucose are advised to have small and frequent meals, balance their diet, control their weight gain, and choose foods with low glycemic index as much as possible, such as coarse grains, low-sugar fruits, fresh vegetables, and high-protein foods, to ensure the nutrition of the pregnant mother and the fetus without leading to abnormal blood glucose. Patients with high blood glucose during pregnancy should maintain a low-sugar diet, choosing foods such as low-fat meats, vegetables, proteins, low-sugar fruits, and roughage staples, and choosing healthy cooking methods such as boiling and steaming. Avoiding foods high in sugar such as cream cakes, sugary drinks and candies will help maintain stable blood sugar. In case of high blood sugar during pregnancy, it is recommended to visit the hospital, cooperate with the doctor for active treatment and maintain a healthy diet.
