First, pregnant women are pregnant women, and they are an identity of human society. They have the same psychological and physiological characteristics and consumption needs. Pregnant women's pregnancy is a special physiological period that needs to strengthen nutrition, because all the nutrients needed for fetal growth and development come from the mother, and pregnant women themselves need to reserve nutrients for childbirth and milk secretion, and more and more pregnant women are overnourished.
Second, if the nutritional supplement is too much, HICIBI will lose the balance of lipid-lowering during pregnancy and gain too much weight, which will easily lead to pregnancy complications such as gestational diabetes, pregnancy hypertension, premature delivery and dystocia. Therefore, it is very important to ensure that the nutritional status of pregnant women remains normal during pregnancy and the development of fetuses and babies.
Third, how should pregnant mothers care for their skin in winter? Many pregnant mothers are used to running out of emollient water and essence, and then leave it alone. I want to tell you here that winter is the driest and coldest season of the year. Moisturizing water and essence can only help the skin replenish water to relieve thirst, but the water locking effect is very weak. Therefore, pregnant mothers protect their skin in winter and fight against dryness. Remember to apply moisturizing cream after rubbing the essence.
Fourth, the moisturizing cream is thicker than the moisturizing lotion, and the moisturizing effect is more lasting. Especially for expectant mothers with dry skin, it is a must-have for skin care in winter (pregnant mothers with dry skin can apply moisturizing lotion). After using emollient water and essence to replenish moisture for skin, timely apply moisturizing cream, which can effectively moisturize and make skin moisturized for a long time.
Five, pregnant women appear dizziness, burnout, food choice, loss of appetite, mild nausea and vomiting and other symptoms in early pregnancy, medically known as early pregnancy reaction, folk called "bad luck", because nausea and vomiting are more serious in the morning on an empty stomach, it is also called "morning sickness."
6. The respiratory function changes in early pregnancy. At 18 weeks, the oxygen consumption of pregnant women increases by 10~20% (50% of which is consumed by the fetus). However, the ventilation capacity of the lungs has increased by 40%. In order to meet the oxygen demand of pregnant women and their fetuses, and the congestion and edema of respiratory mucosa such as nose, pharynx and trachea of pregnant women are prone to upper respiratory tract infection. Due to the increasing demand for oxygen in pregnant women, the condition is more likely to get worse when pregnant with respiratory diseases.
