Why do pregnant women develop diabetes? Diabetes is a relatively common chronic disease for nowadays. When a woman is pregnant, with the weight gain 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 develop diabetes. What are the dangers of gestational diabetes Gestational diabetes is considered bad news for the mother and the fetus. 1.Harm to mother Increase the rate of spontaneous abortion and the incidence of gestational hypertension syndrome; affect the immunity of pregnant women, easy to complicate infection (mostly urinary tract infection and mycobacterial vaginitis); diabetes ketoacidosis during pregnancy, etc.; excessive amniotic fluid, huge babies, and eventually cause obstructed labor and postpartum hemorrhage; when pregnant women with GDM have another pregnancy, the recurrence rate and the chance of developing diabetes in the distant future increases. 2.Harm to fetus Increase the risk of huge baby, intrauterine growth restriction, miscarriage and premature 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 should be extra careful during pregnancy. How can gestational diabetes be prevented and treated? For mothers-to-be, to prevent gestational diabetes during sub-pregnancy, several things need to be done. 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.
