The negative effects of gestational diabetes on pregnancy, fetus and neonate are the same as those of overt diabetes, which may cause excessive amniotic fluid, hyperemesis, giant fetus, malformation and stillbirth; the neonate is prone to respiratory distress syndrome, hypoglycemia, hypocalcemia and erythrocytosis. Oral hypoglycemic drugs can cause severe fetal hypoglycemia through the placenta and should not be used. The current research shows that one of the main and best treatments for gestational diabetes is nutritional therapy. The actual fact is that you can find a lot of people who are not able to get the best out of your own home. The GI (glycemic index) of white bread, for example, is 70, but the bread mixed with 75%-80% of barley grains is 34, so it is advocated to replace refined white bread with bread made of coarse flour with crushed grains. 2, simple is good vegetables can not cut, do not cut, grain can be whole grain do not grind. 3, eat more dietary fiber within the range of intake, more intake of high-fiber foods, such as: brown rice or grain rice instead of white rice, increase the intake of vegetables, eat fresh fruit and do not drink juice, etc. This can delay the rise of blood sugar, help blood sugar control, but also more satiety, but do not eat unlimited amounts of fruit. 4, increase protein in staple foods Increase protein in staple foods can well reduce the GI, for example, the general wheat pasta GI is 81.6, fortified with protein spaghetti GI is 37. dumplings is a better low GI food, because it contains a lot of protein and fiber. 5, stir-fry vegetables should be cooked with rapid fire, add less water Food softness, raw and cooked, thin and thick, particle size have an impact on the GI. The longer the processing time, the higher the temperature, the more water, the better the paste, the higher the GI, so it is best to stir-fry vegetables cooked over a rapid fire, add less water. 6, eat more vinegar Food fermented to produce acid, can make the whole meal of food GI lower, so add vinegar or lemon juice in the side dishes, is also an effective way to regulate GI. Of course, gestational diabetes patients can eat some fruits, but we should pay attention to the type and quantity of choice. 1, choose low-sugar fruits: such as apples, strawberries, nectarines, etc. 2, each time you eat fruit should not be too much, preferably not more than 100 grams. 3, eat in the middle of two meals, do not eat after meals. Generally, you can choose 9:00-9:30 in the morning, 15:00-16:00 in the afternoon, 21:00 before bed at night is appropriate, it is best to choose to eat at mealtime, can be eaten directly as a meal, both to prevent hypoglycemia, but also to keep blood sugar does not occur large fluctuations. And after the meal to eat fruit, for high blood sugar pregnant women is very unfavorable, more should not eat fruit at every meal. 4, after eating fruit, to properly reduce the main food. Usually, for every 100-125 grams of fruit eaten, the main food should be reduced by 25 grams, which is good for regulating blood sugar. Once diagnosed with gestational diabetes, the mothers-to-be should not worry too much, pay attention to diet regulation combined with exercise, relax, I believe that the future blood sugar check will be a surprise.
