1, diet is the basis, food restriction is not advisable Adjustment of diet is an important way to control blood sugar in gestational diabetes, but this does not mean restricting the diet. In general, gestational diabetes patients need roughly the same amount of calories in early pregnancy as before pregnancy, and after mid-pregnancy, calories should be increased by 3%-8% per week, of which carbohydrates account for half, mainly cereals and beans; protein accounts for about 1/4, mainly milk, soy milk, poultry, eggs and fish; fat accounts for 1/3; daily supplementation of calcium 1000-1200 mg, folic acid 5 mg, iron 15 mg, to prevent combined gestational hypertension. Iron 15 mg, to prevent pregnant women from combined gestational hypertension, to avoid fetal development malformations, etc. In addition, pregnant women with gestational diabetes should eat more green leafy vegetables with high vitamin content, and fruits such as strawberries and kiwis with low sugar content, while sugar cane, longan, lychee and desserts with high sugar content should be avoided as much as possible. As each pregnant woman’s body and work situation is different, the daily intake and consumption of energy is also different, in order to meet the growth of the fetus, doctors and dietitians will develop “personalized” recipes according to their weight, height, pregnancy month, etc., so you must follow the doctor’s instructions. 2, regular monitoring of blood sugar, timely adjustment of insulin dosage Due to the special situation of gestational diabetes patients, do not take oral hypoglycemic drugs, otherwise it will easily lead to neonatal hypoglycemia. For pregnant women whose dietary control of blood sugar is not effective, hospitalization is recommended, and the doctor will monitor blood sugar at the right time to determine a reasonable insulin dosage. When insulin is used, patients should measure blood sugar five times a day, namely fasting, two hours after three meals and before going to bed. Fasting blood glucose should be controlled below 5.6mmol/L and 2 hours after meals blood glucose should be controlled below 8.0mmol/L. Once blood glucose is higher than this range, it is important to seek medical attention and adjust insulin dosage. In addition, with the increase of pregnancy, the amount of hormones secreted by the placenta of pregnant women will increase, and the resistance to insulin will gradually increase, and the blood sugar will also change. Therefore, before delivery, the insulin dosage should be increased or decreased at the right time under the guidance of doctors according to the changes of blood sugar level. After delivery, the glucose tolerance of most gestational diabetes patients can return to normal, but some patients will continue to have high blood sugar. Doctors at the Fourth People’s Hospital of Shaanxi Province remind that it is still necessary to closely monitor blood sugar after delivery and use insulin to control blood sugar. Mothers whose blood sugar returns to normal after delivery should not take it lightly, because about 1/3 of pregnant women with gestational diabetes will turn into type II diabetes in 5 to 10 years after delivery. 3, pay attention to pregnancy checkups and closely monitor the development of the fetus Some people with gestational diabetes believe that as long as their blood sugar is well controlled, they will be able to give birth successfully. In fact, in addition to controlling blood sugar, pregnant women with gestational diabetes must also pay attention to pregnancy checkups and closely observe the development of the fetus. In the middle of pregnancy (12~28 weeks), ultrasound will be done every two weeks to check the development of the fetus; kidney function and glycosylated hemoglobin will be measured, and the fundus of the eyes will be examined to check whether the pregnant woman has any comorbidities at an early stage. In the late pregnancy period (after 32 weeks), weekly check-ups should be done to pay attention to the pregnant woman’s blood pressure, edema and urine protein, to pay attention to the maturity of fetal development and monitoring of placental function, and to detect in time whether the fetus has intrauterine hypoxia and other conditions. It is generally recommended that pregnant women with gestational diabetes be hospitalized early at 34~36 weeks of pregnancy to closely observe the condition of the pregnant woman and the fetus. If the pregnant woman’s blood sugar is well controlled, there are no comorbidities, the placenta is functioning well and the fetus is of normal size, she can give birth naturally at full term of pregnancy.
