Currently, there are over 199 million women with diabetes worldwide, 2 in 5 women with diabetes are of childbearing age, and 1 in 7 births are affected by diabetes. So, how does diabetes affect pregnancy and how should diabetes be managed during pregnancy? Why do pregnant women suffer from diabetes “Diabetes is a common chronic disease, and after a woman becomes pregnant, with the increase in weight and some hormones and cytokines produced by the placenta, it interferes with the normal work of insulin in the body, so pregnant women are prone to diabetes.” What are the hazards of gestational diabetes 1, the hazards to the mother Increase the rate of spontaneous abortion and the incidence of gestational hypertension syndrome; affect the immunity of pregnant women, easy to complicate the infection (mostly seen urinary tract infections and mycobacterial vaginitis); diabetes ketoacidosis during pregnancy, etc.; excessive amniotic fluid, huge children, and eventually cause obstructed labor, postpartum hemorrhage; GDM pregnant women again when pregnant, the recurrence rate and the chances of developing diabetes in the distant future increased. 2.Harm to fetus Increase the risk of huge baby, intrauterine growth restriction, miscarriage and preterm birth; higher rate of fetal malformation than non-diabetic pregnant women; increase the incidence of difficult shoulder delivery and various birth injuries. 3, the harm to the newborn increase the incidence of neonatal respiratory distress syndrome, neonatal hyperbilirubinemia, hypocalcemia and hypomagnesemia; newborns are prone to hypoglycemia. In addition, babies born to pregnant women with diabetes have a higher risk of autism and mental retardation than babies born to healthy pregnant women. Based on these foreseeable risks, it is recommended that mothers-to-be be extra careful during pregnancy. How to prevent and control gestational diabetes For mothers-to-be to prevent gestational diabetes during sub-pregnancy, they need to do several things. Weight control: to prevent gestational diabetes, the first thing to do is to control weight, pre-pregnancy weight should be controlled within a reasonable range, the total weight increase during pregnancy should not exceed 10 kg, to no more than 2 kg per month is appropriate. Diet control: Diet control during pregnancy should not only ensure and provide calories and nutritional needs, but also avoid the appearance of postprandial hyperglycemia or starvation ketosis to ensure normal fetal growth and development. Choose carbohydrates with low glycemic index as much as possible; you can have small and multiple meals, divided into 5-6 meals per day. Moderate exercise: moderate and reasonable exercise can effectively improve insulin sensitivity, reduce basal insulin resistance during pregnancy and promote glucose metabolism, thus lowering blood glucose levels; however, the principle of not affecting the fetus and not causing contractions should be followed. The Chinese medicine believes that “a woman’s liver is her precursor”, and women are most likely to be hurt by emotions, resulting in liver qi stagnation. The occurrence and development of diabetes are related to emotions. Therefore, gestational diabetes patients should maintain an optimistic and cheerful mood to facilitate the control and recovery of the disease. Active treatment: If blood sugar cannot be controlled by diet therapy, it is recommended to use insulin to control blood sugar under the guidance of a doctor.
