During pregnancy, blood glucose control is more stringent. Pregnant women can control their blood glucose by adjusting their diets and exercising moderately, injecting insulin when necessary, and generally not using oral hypoglycemic drugs. 1. Adjusting diet: Pregnant women should limit their calorie intake while ensuring adequate daily nutrition. Need to improve the diet structure, avoid eating fatty meat, cakes, cream and other high-fat, high-sugar food, can try to choose miscellaneous food instead of fine staple food. Pay attention to control weight gain. 2. Moderate exercise: during pregnancy, you can take a walk after meals, or through yoga, maternity exercises and other sports to help control blood glucose, but it is not recommended to carry out strenuous exercise to avoid increasing the risk of miscarriage. 3. Insulin therapy: If it is still difficult to control blood glucose after lifestyle intervention, insulin therapy should be considered, but the amount of insulin should strictly follow the doctor’s instructions to prevent hypoglycemia caused by excessive dosage. During pregnancy, blood glucose should be strictly monitored, regular medical checkups should be conducted, and the doctor should be informed of any abnormality in time.
