How to control high blood glucose in pregnant women, first of all, it should be determined whether the degree of high blood glucose in pregnant women has reached the diagnosis standard of gestational diabetes. If it reaches the standard of gestational diabetes, it should be controlled in accordance with the treatment of diabetes, mainly including diet control, appropriate exercise, application of insulin and other methods. 1, diet control: pay attention to eat less high-sugar, high-calorie, high-fat, high-protein food, eat more dietary fiber-rich grains and cereals. It is best to have one meal a day with coarse grains, mixed grains instead of refined rice and refined noodles, the best effect on diabetic diet control, in addition to eating less and more meals. In the process of pregnancy, the uterus gradually increase, compression of the intestines, making the intestinal peristalsis slow, eat more dietary fiber-rich grains and cereals, can help the intestinal peristalsis, reducing the risk of constipation in pregnant women; 2, appropriate exercise: including pregnant women exercise, pregnant women yoga, can effectively help blood sugar drop. Proper exercise can increase the sensitivity of peripheral tissues, especially muscle tissues to insulin, and achieve the effect of lowering blood sugar; 3, application of insulin: after diet and exercise control, blood sugar is still not up to standard, such as fasting blood sugar ≥ 5.1mmol/L, 1 hour after meal blood sugar ≥ 10.0mmol/L, 2 hours after meal blood sugar ≥ 8.5mmol/L, insulin should be used for control. Because only insulin can be used during pregnancy, but not oral hypoglycemic drugs, which can affect the fetus through the placenta. If the glucose level is higher than normal, but not yet reached the diagnosis of gestational diabetes, you need to strengthen the management of diet and exercise to increase the body’s basal metabolic rate to control high blood sugar. In addition, you should increase the frequency of blood glucose testing and pay attention to the changes of blood glucose. Hyperglycemia has certain risks for both pregnant women and fetuses. For pregnant women, it may lead to various acute infections and excessive amniotic fluid, which may lead to giant babies and neonatal diabetes.
