Pregnant women with high blood glucose should first consult a medical professional to clarify their condition. Lifestyle interventions for high blood glucose can be made by adjusting dietary structure, increasing physical activity, etc., and monitoring whether the blood glucose is under effective control. If blood glucose is still out of normal range, insulin therapy may be activated under the guidance of professional doctors. 1. Dietary control: Choose foods with low glycemic index as much as possible. Small and frequent meals should be practiced, divided into 5~6 meals per day, with 1/3~1/2 of the staple food divided into additional meals to help control postprandial blood glucose. 2. Exercise: Encourage appropriate exercise during pregnancy, including aerobic exercise and resistance exercise, such as yoga and walking. The duration of each exercise is less than 45 minutes. Regular exercise can increase insulin sensitivity. 3. Insulin therapy: For both fasting and postprandial glucose elevation, short-acting or rapid-acting insulin combined with intermediate-acting or diethylstilbestrol before three meals is recommended. Pregnant women who find high blood glucose should consult a doctor in time to clarify their condition.
