Low pre-pregnancy weight has a large pregnancy reaction When a woman is first pregnant, the pregnancy reaction not only affects her appetite, but also causes a decrease in gastrointestinal digestive function, resulting in nutritional loss. Therefore, in addition to avoiding illness and improving lifestyle before pregnancy, it is also important to maintain the weight in the normal range. For example, Ms. Zhang, who is 1.65 meters tall, weighed less than 45 kilograms before pregnancy, and her physique was poor, so once she became pregnant, her pregnancy reactions such as loss of appetite and vomiting were stronger than the average person. Not eating for a long time, nutrition is not guaranteed, but also lead to intrauterine fetal development delayed, affecting brain and physical development. Suggestions: Before pregnancy, women should maintain their weight in the normal standard range, with a body mass index (i.e. weight in kilograms divided by height squared) better between 18.5 and 24; at the same time, women who are preparing for pregnancy should pay attention to increasing the intake of high-quality protein and eating more seasonal vegetables and fruits, seafood and foods rich in folic acid. You can’t deliberately diet during pregnancy 30-year-old Ms. Zhou is a white-collar worker who is more than 3 months pregnant. As her company stipulates that once pregnant to be terminated, in order to be able to work for a few more months, she has not said to people that she is pregnant, usually too busy to eat, but also as usual hungry. “Eat one or two meals less, weight gain a little slower, others can also be later to see that I am pregnant.” Ms. Zhou said. There are many people like Ms. Zhou who intentionally eat less and control their weight during pregnancy, in fact, the fetus needs adequate nutrition for healthy growth in the mother’s body, if the mother’s nutrition supply is insufficient, it will affect the development of the fetus and even cause premature birth, miscarriage, stillbirth, low weight baby or baby born with poor health, etc.; poor nutrition during pregnancy may lead to anemia, weakness, back pain, etc. The principle of comprehensive nutrition and balanced diet should be adhered to during pregnancy in order to provide the baby with the required nutrients, and the weight gain of the mother-to-be should be controlled within the range of 10 to 12 kg throughout pregnancy. Suggestions: Early pregnancy (1~12 weeks): the diet is comparable to that before pregnancy, due to pregnancy reaction, there will be vomiting, but don’t be afraid to eat and vomit, even if you vomit, you still have to eat, the weight gain during this period is controlled within the range of 2~3 kilograms is appropriate. Mid-pregnancy (13~28 weeks): due to the growth and development needs of the fetus, the mother-to-be has more nutritional needs, at the same time, the gastrointestinal tract and other pregnancy reactions are lighter, so you can add meals, increase the intake of energy and protein, eat more milk, eggs and other high-quality protein, and control the weight gain at 4~5 kg during this period. Late pregnancy (29 weeks ~ prenatal): take the principle of eating less and more meals, eat three meals to 60% full in the morning, midday and evening, add three meals in the morning, afternoon and evening, you can drink a glass of milk, eat a few nuts, etc.. Add some calcium-rich foods and sunbathe for 1 to 2 hours a day to help your baby’s bones and brain develop better. The weight gain during this period is controlled at about 4 kg.
