Pregnant mothers are always worried that their children will be undernourished and overeat, especially during the Spring Festival holiday, which will eventually lead to their children being overweight. This not only causes an overburden for the pregnant woman, but also increases the risk factors for childbirth, and also creates hidden dangers for the health of the child in the future.
Throughout pregnancy, it is normal for a pregnant mother to gain about 12.5 kilograms of weight. What does this 12.5 kg contain? The first is the products of pregnancy, such as the fetus, placenta, and amniotic fluid, which add up to a total of 4.7 kilograms; the second is the growth of maternal breasts, uterus and other tissues, as well as blood and extracellular fluid, which adds up to a total of 3.75 kilograms; the third is the fat reserved for breastfeeding, which is about 4 kilograms. . Among them, the increase in fetal, placenta, amniotic fluid, plasma volume and breast and uterine enlargement are called basic weight gain.
The rate of weight gain is different in different periods after pregnancy. The recommended average weekly weight gain for each period of pregnancy is as follows:
From 0 to 10 weeks of pregnancy, the gain is 0.65 kg; from 10 to 20 weeks, the gain is 0.335 kg per week; from 20 to 30 weeks, the gain is 0.45 kg per week; from 30 to 40 weeks, the gain is 0.33 kg per week.
Under normal circumstances, after a woman becomes pregnant, she will gain about 4 kilograms of fat. From 10 weeks to 30 weeks of pregnancy, the embryo has not yet grown rapidly. During this period, the pregnant mother\’s body fat increases the fastest. After 30 weeks of pregnancy, the fetus grows rapidly, while the increase in body fat of the pregnant mother tends to slow down. The increase in body fat during pregnancy is a reserve of energy needed for lactation at the end of pregnancy or postpartum, and is extremely important for lactation. Fat storage during pregnancy is concentrated in the abdomen, back and upper thighs.
The weight of pregnant women is an important indicator of nutrition during pregnancy. Too much or too little weight is not good for the health of mother and child. If the child is too large, with a birth weight greater than 4 kilograms, it is called macrosomia, which is a pathological weight and is prone to various complications such as postpartum hypoglycemia after birth. Even if it does not appear immediately after delivery, it will cause secondary obesity and significantly increase the risk of hyperlipidemia, hypertension, cardiovascular and cerebrovascular diseases, and diabetes. Therefore, weight should be weighed and recorded weekly starting in the second trimester, and food intake should be adjusted based on weight gain.
