1. Changes in physiological structure

Weight gain is an important and obvious physiological change during pregnancy. In addition to the weight of the fetus, placenta and amniotic fluid, the mother herself has also undergone some changes due to endocrine changes. For example, with the increase of estrogen, women's fat also increases; Lutein rose; Prepare for breastfeeding, let the prolactin be more, and so on.

Generally, pregnant women gain 13-20kg during pregnancy, of which 7kg is fat cells. After giving birth to a baby and losing a lot of water, my mother still has 7 pounds of fat. If she doesn't lose weight properly, the fat will follow her all her life.

2. Changes in living habits

Pregnancy: The instructor of the weekly weight-loss class and the attending doctor of obstetrics and gynecology said that there are many people who lose weight repeatedly, and 70% of them are caused by bad lifestyles.

In order to let the baby in the womb absorb enough nutrition and grow up healthily, pregnant women follow the principle of "one person to eat, two people to supplement", forget the dietary concept that was previously taboo because of fear of obesity, and try to eat more "supplement" food, hoping to make the fetus get enough nutrition. However, some expectant mothers "make up" the wrong food, but they consume too many calories, which is fat for the mother herself, but the fetus may not absorb nutrition. It is not uncommon for a mother to gain more than 20 kilograms, but the baby is born with two or three kilograms. In the future, her slimming process will be more difficult and more difficult.

Confinement period: In order to achieve the purpose of postpartum tonic, the traditional confinement method is to eat a lot of sesame chicken, stewed pig's trotters with peanuts, high-calorie internal organs and other foods; Experts in the field of production reduction said that modern people must correct the concept of eating too much oil in confinement; Because people lived in poverty in the past, they were generally malnourished; Coupled with the underdeveloped medical technology, pregnant women bleed a lot during childbirth and are weak. Therefore, foods rich in oil, wine and protein are used for tonic, but they mainly provide calories, not nutrition.

Nutritionists say that the common problem of modern people is too much calories, but not enough nutrition. Therefore, postpartum confinement should pay attention to the intake of cellulose, help defecation, relieve constipation and restore slim figure.

Influence 2: Causes of postpartum breast ptosis

Associate Professor Liu Yinglin from the Department of Obstetrics and Gynecology, Sun Yixian Hospital, Sun Yat-sen University explained that during lactation, the hyperplasia of glands and connective tissues in the breast will make the breast bigger, and mommy's breast will also swell due to the accumulation of a large amount of milk. However, because of feeding the baby, the skin on the surface of the breast is stretched and expanded, and the elasticity of the suspension support structure of the breast is also reduced. At the same time, after lactation, glands atrophy and breasts become smaller and droopy. "This is an inevitable influence. However, some mothers do not pay attention to breast protection during lactation and after lactation, which leads to breast atrophy, which is completely preventable. "

Influence 3: Common causes of postpartum vaginal relaxation

Vaginal relaxation refers to the reduction of the tension of pelvic muscles, which relaxes the muscles around the vagina and widens the vagina. There are many reasons for postpartum vaginal relaxation. The fetus is too big (the head is too big), which causes birth injury during natural delivery. Vaginal injury caused by mid-term induced labor; Several deliveries; Lack of exercise after delivery; Postpartum recovery blindly lose weight, neglect nutrition or overwork, resulting in poor pelvic muscle recovery and so on.

For mothers who give birth naturally, because the fetus is delivered through the vagina, the head diameter of the baby born generally is about 10 cm, that is, the vagina should be expanded to 10 cm during delivery (the normal vaginal diameter is 2.5 cm). After being squeezed by the born child, the vagina is obviously expanded, the muscles and hymen traces are completely destroyed, and the elasticity is obviously reduced. However, although the vagina of the mother who gave birth to the fetus from the vagina has changed, there will be different degrees of vaginal relaxation. However, it does not mean that natural childbirth is the chief culprit of vaginal relaxation, because during labor, the pelvic muscles and ligaments will be fully stretched to prepare for the birth of the baby. Therefore, even a mother who has a caesarean section will have a loose vagina.

Influence 4: the cause of stretch marks.

Since the second trimester, many reddish or purple stripes have gradually appeared on the skin of expectant mothers' abdomen, inner thighs, buttocks and chest, indicating that even if they plan to get pregnant, 9 months is not enough for couples to adapt to the extra hardships of taking care of their babies.

Babies may be born early, which may lead to stress changes in family and daily work, which parents often do not expect. If the baby has birth defects, it is even more difficult for parents to accept it.

Complex emotions sometimes come from her past experiences. She may have lost her mother prematurely, or she may have a bad relationship with her mother. This will lead to her lack of confidence in the baby's feelings. She may worry that raising a child will lead to pain, disappointment or loss.

3. Lifestyle

A major factor of postpartum depression is the lack of support from others. The stable support of the new mother's spouse is the best comfort during pregnancy and postpartum. Spouses are willing to take on housework and share the care of the baby, which is very helpful. If the mother is single or not at home, she will lack such support.

Some problems in breastfeeding will make new mothers feel depressed. There is no need to feel guilty if the new mother can't breastfeed or decides to stop breastfeeding. Nutritional formula can also raise babies well. Your spouse can also give your baby some help.
