Gestational diabetes, which is mostly caused by a relative lack of insulin secretion, can be solved in more than 80% of cases by dietary modification, i.e., eating less and more meals. More than 80% of the cases can be solved by dietary modification, i.e., eating fewer and more frequent meals. Pregnant women who are diagnosed with gestational diabetes need to adjust their diet for at least one week, i.e. meal sharing or eating less and more meals, before they can do the small profile test (monitoring the change of blood glucose throughout the day) to decide whether they need to be treated with insulin. Other considerations are as follows: 1. Meal system: Breakfast: the usual amount of breakfast can be seven or three points, eat a meal at eight in the morning about seven or eight points full, and then add a meal at ten, which can reduce a meal full of insulin is not enough, resulting in increased blood sugar. Chinese food: you can eat completely full without meals, 3-4 pm can be a little extra meals, such as snacks, fruit, etc.. Dinner: basically eat full, to about 10 pm a little extra meal, can be half a bowl of noodles, dumplings, snacks, fruit, etc., to reduce the morning hunger, thus reducing the amount of breakfast eating. 2., monitoring blood sugar: choose any whole day (except weekends or holidays) to the surgical building nine. , tenth floor (obstetrics ward) nurse station to measure blood glucose five times, namely fasting, 2 hours after breakfast, lunch and dinner, and blood glucose before bedtime. Bring your breakfast to measure fasting blood sugar, then start eating breakfast, start timing from the first bite, finish eating within 15 minutes, timing two hours, measure blood sugar two hours after breakfast, so measure blood sugar two hours after Chinese meal and dinner. The last blood glucose is measured before bedtime, at least after 10 o’clock, and you can go home to rest after the measurement. Note: If you feel hungry obviously, you can eat a little after measuring blood glucose two hours after meal, do not eat within two hours to avoid affecting blood glucose results. On the other hand, the test day must be restored from the previous multiple meals a day to three meals a day, and each meal must be full, do not eat less in order to pass the blood glucose, which will affect the judgment. By the way, when doing the 75g OGTT test, venous blood must be drawn for the test, while for the small profile test, only finger blood is tied, i.e., peripheral blood is used for the test, so there is no need to be afraid of drawing blood! The diabetic diet advocated is: scientific, reasonable eating, provide a reasonable total calorie, to ensure a variety of nutrients, and a reasonable proportion, in line with physiological needs. The key is quality and quantity, as well as the timing of meals. That is, what to eat, how much to eat, what time to eat, for some points in time poor blood sugar control, under the premise of the total calories remain unchanged can be divided into meals, conducive to blood sugar control. The purpose of dietary adjustment is: the intake of nutrients should not only meet the needs of fetal growth and development, but also try not to overload the mother’s pancreatic function (insulin)… When fasting blood sugar is greater than 5.3 mmol/L and 2 h postprandial blood sugar is greater than 6.7 mmol/L, it is generally necessary to add insulin therapy. The latest view is that when fasting blood glucose is greater than 6.0 mmol/L and 2 h after meal blood glucose is greater than 8.0 mmol/L, then insulin therapy is needed. The common misconceptions about diabetic diet therapy are: one misconception is that diabetic diet therapy is starvation therapy, and that blind long-term starvation will definitely weaken a person’s resistance and cause serious ketoacidosis. The second misconception is that diabetic diet therapy is to eat more meat and less food, in fact, even if you do not enter a grain, only eat meat, fish, vegetables, etc., blood sugar can not be controlled … because too much fat interferes with the use of sugar or converted into sugar, but also easy to promote atherosclerosis. The third misconception is that diabetic dietary treatment is to eat more vegetables, not to eat or less meat food, diabetic resistance is low, do not eat protein food, resistance is even lower. The fourth misconception is that the danger of too little diet may lead to intrauterine growth retardation or growth restriction of the fetus.
