Meng Meng became a mother for the first time. In order to let the fetus absorb enough nutrition, she also ignored her image. All kinds of soups and nutrients were collected by the order, and all of them were eaten in her stomach. My mother-in-law is very happy to see her so obedient.
However, during the prenatal examination, her mother-in-law found that she ate a lot, but the weight of the fetus did not increase much. What happened? In fact, the weight gain of pregnant women is not always reflected in the weight of the fetus.
The weight gain of pregnant mothers mainly comes from four categories:
1. Fetal weight increased by 5.9-8. 16 kg.
The weight of pregnant women has increased, and the largest proportion is fetal weight. Fetal weight will increase with gestational age, reaching 1 kg at 24 weeks, 4 kg at 32 weeks and 6-8. 16 kg at 40 weeks.
2. Pregnant women's own fat reserve is 5.44-7.26 kg.
The fat reserve of pregnant women refers to the fat content that pregnant women increase through diet during pregnancy, and the fat content of pregnant women reaches a peak of 7.26 kg at the 40th week of pregnancy. This part of fat content will not disappear with the delivery of pregnant women, but will still remain in pregnant women after delivery. Mothers can lose weight through exercise or fitness.
3. The body fluid, blood flow and breast weight of pregnant women have increased, which increased by 5.42-9.08 kg during pregnancy.
At different stages of pregnancy, the contents of body fluids and blood flow of pregnant women will also increase or decrease, and will gradually fade after delivery.
4. Placenta, amniotic fluid volume and uterus increased by 4.96 kg during pregnancy.
Amniotic fluid will gradually increase in the first and second trimester of pregnancy, but in the third trimester, the amount of amniotic fluid will gradually stabilize, generally between 800- 1000 ml.
During the whole pregnancy, pregnant women * * * increased by 2 1.72-29.46kg, but after delivery, the weight of pregnant women will decrease by 1.32- 1.5kg, and the weight of fetus, amniotic fluid and placenta will decrease.
The normal range of pregnant women's weight gain is 20-25 kg, but due to the influence of pregnant women's pre-pregnancy weight, pregnant women's weight gain will vary from person to person.
Lean pregnant women gain 25-36 kg during pregnancy, medium pregnant women gain 23-32 kg during pregnancy, and overweight pregnant women gain 14-23 kg during pregnancy. Obese pregnant women, * * * increase during pregnancy 10- 18 kg.
The thinner a pregnant woman is before pregnancy, the more weight she needs to gain, and the fatter she is before pregnancy, the less weight she needs to gain. This is also considering the problem of fetal nutrient absorption. If pregnant women are too fat and eat too much nutrition, then the fetus absorbs too much nutrition, which is easy to give birth to giant babies.
If pregnant women are too thin and eat too little nutrition, it will lead to fetal growth retardation and even affect the development of fetal brain. If the fetus is underweight, then pregnant women need nutritional injections to promote the development of the fetus, so as to achieve the goal of reaching the fetal weight standard.
Pregnant women need to control their weight during pregnancy so that their weight can increase within a reasonable range. The better the weight of pregnant women is controlled, the fetal weight will not increase excessively. If pregnant women are overweight during pregnancy, they not only need to stay away from high-fat and high-energy foods, but also need to limit the intake of starch, high-sugar fruits and oils in their diet. After all, it's easy to gain weight and painful to lose weight.
