Gestational diabetes can seriously affect the health of the mother and baby. If the blood sugar control during pregnancy is not ideal, pregnant mothers are prone to hypertensive disorders of pregnancy, excessive amniotic fluid, infections and other symptoms, but also increase the chances of difficult labor and cesarean section; high blood sugar during pregnancy may also lead to miscarriage, malformed babies, preterm delivery, intrauterine growth restriction of the fetus, macrosomia, neonatal respiratory distress syndrome, neonatal hypoglycemia and other diseases, the baby is very harmful. To prevent gestational diabetes, it is necessary to check fasting blood glucose and glycosylated hemoglobin in early pregnancy to exclude pre-pregnancy diabetes, eat less sweets and greasy food during pregnancy, and do OGTT test at 24~28 weeks of pregnancy. If diagnosed with gestational diabetes, be sure to strictly control your diet and seek medical attention if you have any problems. Gestational diabetes in the diet should pay attention to four principles: 1, choose foods with a low glycemic index Glycemic index is also known as the glycemic index (GI), to understand the glycemic index of food on the rational arrangement of meals, blood glucose control level has an important role. When eating the same amount of food, foods with a low GI are more helpful in controlling postprandial blood sugar. It is recommended that at least 1 ~ 2 meals a day to choose low, medium glycemic index staple food, such as breakfast can eat buckwheat noodles, etc.; lunch or dinner choice of mixed rice or vegetable dumplings and meat. 2, increase the protein in the staple food in the daily diet, can be appropriate to increase the protein of the staple food, pregnancy sugar mothers can choose a lower glycemic index of the staple food, less consumption of high glycemic index of the staple food, meals can be paired with a variety of dietary fiber-rich side dishes, such as a variety of vegetables, seaweed (such as kelp, seaweed). 3, strictly control the amount of food Many pregnant mothers are concerned about whether gestational diabetes can eat sweets and fruits. Gestational diabetes is related to many factors, such as genetics, exercise, diet and so on. Gestational diabetes is not directly related to eating sugar, but is related to excess energy, whether it is staple foods or fruits or snacks, eating too much may lead to excess energy, which in turn affects blood sugar. Therefore, patients with gestational diabetes must strictly control the amount of food, and generally do not advocate eating candies, dried fruit, sweet drinks, sweet cookies, pastries, ice cream, etc. with added sucrose, glucose, maltose, and so on. Eat fruit should also choose less sugar and low glycemic index fruit, appropriate between meals or eat before bed, if you eat fruit should be reduced accordingly staple food. 4, choose the correct cooking method There are many factors affecting the glycemic index of food, including the softness and hardness of food, thinness and consistency, particle size, degree of pasting of starch, and dietary fiber content, etc. The way food is prepared and cooked is one of the most important factors affecting the glycemic index. Incorrect cooking methods should be avoided to increase the glycemic index of food. When cooking, the following points should be noted: do not process too fine; eat some appropriate coarse grains; cook as much as possible rapid fire and fast cooking; in addition to the special needs of cereal food, do not add too much water and heating time is too long, because it will make the food paste high degree, and the Glycemic Index is also increased. In addition, cooking food to increase the appropriate acidity can also reduce the food glycemic index, such as cooking with a little vinegar or lemon juice. Gestational diabetes patients should combine appropriate exercise with dietary control. Generally can be an hour after the meal for walking, gymnastics and other more relaxed and gentle activities, avoid strenuous exercise, exercise should not be too long, generally about 20 to 30 minutes, in the exercise process should pay attention to observe whether there are contractions, if you feel fatigue, contractions to rest immediately. It should also be noted that people with preterm labor or other serious complications should not exercise.
