Diabetes mellitus is a relatively common and serious metabolic disease, mainly characterized by hyperglycemia, usually without obvious symptoms, but with serious complications. During pregnancy, women are prone to gestational diabetes, a disease that can have bad effects on both mother and child. Many pregnant mothers will deny their disease, believing that they are not physically ill, but only have high blood sugar from eating too much sweet food, and are complacent about the doctor’s comment that the fetus is huge, believing that the bigger the fetus the better. Diabetes during pregnancy not only makes the fetus huge and increases the risk of cephalopelvic disproportion, obstructed labor and vaginal laceration, but also has the risk of growth restriction and even malformation and stillbirth, and newborns born to diabetic mothers are prone to hypoglycemia, neonatal respiratory distress and neonatal retinopathy. Diabetes during pregnancy, diet control is the first step, if the diet control is not good, pregnant mothers should consider insulin treatment. What should I pay attention to during pregnancy diabetes? 1, try to avoid fried food. Fried food contains high fat and high quality, which will not only make pregnant women gain weight too fast, but also increase the incidence of gestational diabetes. 2, try to avoid eating “sugar” diet. Sugar, not only refers to sweet food, but also includes food containing more starch, maltose, fructose, such as steamed bread, potatoes, lotus, pumpkin, bananas, longan, sugar cane, etc.; 3, moderate nutrition, maintain a healthy diet, proper exercise, and maintain a normal weight. Studies say that patients with high blood glucose or diagnosed diabetes during pregnancy have a 1/3 chance of developing true diabetes after delivery, so it is also important to pay attention to a light diet after delivery, adhere to a high fiber, low-fat and low-sugar diet, and perform another OGTT test 6 to 12 weeks after delivery to determine.
