" in general, pregnant women after pregnancy weight will gradually increase, the growth range according to the needs of their own conditions such as pregnant women, pre pregnancy weight, height and other factors. Maternal weight data interpretation is that in the early pregnant women body weight increased by 1-2kg, because the fetus is limited absorption of nutrients, so weight should not be increased too much.
in the second trimester and the second trimester of pregnancy, the body weight increased by about 5-6kg, or about 0.4kg. In the second trimester, the weight gain of pregnant women was mainly due to the changes of maternal physiology, including the increase of blood volume, the increase of the weight of uterus, breast and related tissues, and the storage of fat. The increase of body weight of pregnant women in late pregnancy is mainly caused by fetal development, fetal, placental weight gain and amniotic fluid increase will lead to weight gain.
gestational weight gain standard
ideal body weight equal to height minus 100, that is IBW (kg) =Ht (CM) -100. Experts designed a more accurate body index equal to the body weight divided by the square of height, that is IBM=Wt (kg) /Ht (m) 2. Normal women's BMI is 20~26. The following is the recommended weight gain in pregnancy.
BM height and weight before pregnancy BM pregnancy should be increased weight.
slim BM (< 90%IBW, BMI < 20), BM=12.5~18kg;
(90%~120%IBW, BMI=120~26) - BM, BM=11.5~16kg;
(120%~135%IBW, BMI=26~29) full BM, BM=7~11.5kg;
BM (obesity > 135%IBW, BMI > 29), BM=6~7kg.
younger or slim, pregnancy can increase nutrition to make weight gain more. Obese people just need to balance the nutrition so that less weight gain, so that the fetus to share too much fat. Maternal weight gain in pregnant twins was appropriate for 15~20kg.
normal pregnant the first 3 months of the monthly increase in weight about 0.5 kg, but because of the pregnancy reaction, nausea, vomiting and anorexia, often pregnant weight loss; 5 months of pregnancy weight increased rapidly, an increase of about 0.45 kg per week, but not more than 0.5 kg, or to pay attention to pregnancy induced hypertension; 7~8 a month of pregnancy, weight gain slow; full-term pregnancy weight increases no longer.
some of the young women, in order to keep slim and pray for childbirth smoothly and diet, resulting in fetal malnutrition after birth, infirm, increased parenting difficulties. And some older pregnant women eager to fetal health, eating too much, the result is too large, the need for cesarean delivery, delayed lactation or even milk, but the adverse health of newborns. Especially in maternal tonic and ginseng, pilose antler more careful, supplement for pregnant women and fetuses have adverse effects.
pregnant women will exceed the weight of
pregnant women at least once a month during pregnancy weight. Under normal circumstances, the first three months can be increased by 1.1~1.5kg. After 3 months, weight gain should still be controlled at around 0.5 kg / week. To term delivery, weight should be increased by about 12.5 kg before pregnancy. Pregnant women in accordance with this index to calculate the weight, if found overweight or weight gain is too fast, should adjust the diet structure.
if pregnant women overweight, pregnant women and fetuses are unfavorable.
for pregnant women, overweight mothers suffering from pregnancy complications were higher than normal mothers, these complications including gestational hypertension, gestational diabetes, thrombosis and postpartum depression. In addition, overweight mothers increase because of macrosomia rate, resulting in the use of forceps delivery and cesarean section rate increased dystocia, increased maternal injury, and easily lead to postpartum hemorrhage and infection.
for the fetus, because of dystocia, fetal birth rate increased incidence of these diseases, including intracranial hemorrhage, clavicle fractures, brachial plexus injury and paralysis, and even neonatal asphyxia and death. The incidence of type 2 diabetes, hyperlipidemia and cardiovascular disease in adults was significantly higher than that in normal subjects. Although the majority of obese mother fetal weight is too large, but also visible in clinical small part of obese mothers during pregnancy, intrauterine growth restriction gives birth to low birth weight, which may affect the placental functions and fat deposition.
how to control the weight of pregnant women
how to control the weight of pregnant women? During pregnancy should try to absorb nutrients from a balanced diet. Eat more foods rich in quality protein, snacks are best to eat less. According to the maternal weight growth of different, should control weight:
1, maternal body weight:
if pregnant women are overweight, do not eat high calorie foods, such as peanut butter, nuts, can eat boiled tuna, low-fat cheese etc.. At the same time, in order to ensure adequate nutrition to the fetus, it is recommended under the guidance of doctors and nutritionists, weight management. In addition, do not hunger, so as to avoid their own health and fetal growth and development of adverse effects.
2, pregnant women underweight:
for underweight pregnant women, three meals a day to eat a balanced diet. Because most of the body of the fetus is formed by the protein, it is recommended that pregnant women eat more fish, red meat, tofu and other foods containing high protein.
3, how to control weight during pregnancy:
remember that daily meals should be consistent with high protein and low calorie. Milk and milk products, bean curd and natto contain high protein.
