(1) Having children can reduce the incidence of ovarian cancer.
Because pregnancy and childbirth can inhibit ovulation, current statistics show that the occurrence of ovarian cancer is related to infertility or fewer births. Giving birth at least once can play a protective role and reduce the risk of ovarian cancer by 30%~40%.
(2) More births increase the incidence of cervical cancer.
Because the vast majority of cervical cancer is related to human papillomavirus infection, and human papillomavirus is sexually transmitted, the high risk factors of cervical cancer include young age of first sexual intercourse (< 16 years old), multiple sexual partners, frequent delivery and so on.
(3) Having children can reduce the incidence of endometrial cancer.
The occurrence of endometrial cancer may be related to estrogen stimulation without progesterone for a long time, so pregnancy and childbirth are a protective factor. According to statistics, the risk of endometrial cancer in women who have never given birth is 2~3 times that of women who have given birth.
(4) Having children can reduce the incidence of breast cancer.
The risk of breast cancer is related to the length of a woman's reproductive period. Women who have never been pregnant have a higher risk of breast cancer than multiparas, and women who give birth to their first child late have a higher risk of breast cancer than women who give birth early.
2. Giving birth to a child will lead to organ damage. In addition to malignant tumors, pelvic organ prolapse and dysfunction of urination and defecation are also common diseases in middle-aged and elderly women.
(1) More deliveries will increase the risk of urinary incontinence in young women.
During pregnancy and postpartum, some women will have urinary incontinence, which is obviously related to the number of deliveries; However, if women over the age of 60 have urinary incontinence, the influence of delivery times is not so important, and other factors have greater influence.
(2) Having children increases the risk of abnormal defecation function.
One of the most common causes of abnormal defecation function or fecal incontinence in women is the injury during childbirth.
(3) Having children will increase the risk of pelvic organ prolapse.
The risk factor of pelvic organ prolapse is vaginal delivery. Women who have had at least one vaginal delivery have twice the risk of pelvic organ prolapse as men.
To sum up, in the long run, pregnancy and childbirth can reduce the incidence of ovarian cancer, endometrial cancer and breast cancer in women; However, having more children is a high risk factor for cervical cancer; At the same time, having children is a high risk factor for women to have dysfunction of urination and defecation and pelvic organ prolapse in the future.
—— Short-term risk return 1, cardiovascular system
During pregnancy and childbirth, the increase of human blood volume and heart load may lead to hypertensive disorder complicating pregnancy; Moreover, for women with cardiac insufficiency before pregnancy, pregnancy and childbirth will aggravate this situation.
2. Respiratory system
During pregnancy, the ventilation and oxygen consumption of pregnant women at rest increase, which can lead to a variety of lung diseases. Among them, acute pulmonary edema is one of the most common reasons for women to transfer to ICU during pregnancy and postpartum. Because pregnancy can suppress the immune system, the risk of catching a cold after pregnancy will increase.
3. Blood system
Because of the increased blood volume and hypercoagulability during pregnancy, the risk of anemia and thrombotic diseases during pregnancy is increased.
4. Endocrine system
Gestational diabetes mellitus (GDM) is easy to occur due to the decline of glucose metabolism during pregnancy, and the difficulty of blood sugar control in diabetic patients after pregnancy increases accordingly.
5. Digestive system
The mechanism of physiological changes in human gastrointestinal tract during pregnancy is not very clear, but many people will have nausea, vomiting, constipation, hemorrhoids and other manifestations. However, digestive tract ulcers are not common during pregnancy. Women with digestive tract ulcers will get better after pregnancy.
6, urinary system
Due to the increased renal load during pregnancy, although the risk of lower urinary tract infection during non-pregnancy has not changed, if a woman has renal insufficiency before pregnancy, the renal damage will usually increase after pregnancy.
7. Motion system
During pregnancy, especially in the third trimester, the weight gain of pregnant women is a challenge to the musculoskeletal system, and many people will have low back discomfort or pelvic pain. Although most people will gradually recover after delivery, there are still a few people who may be delayed for a long time.
To sum up, in the near future, the impact of pregnancy and childbirth on women is undoubtedly enormous. Judging from the changes of various systems, most of them are adverse effects, and complications such as postpartum hemorrhage and amniotic fluid embolism during delivery have not been considered.
You know, the maternal mortality rate in China is 32/65438+ 10,000, so you don't have to bear these extra death risks if you don't have children.
Women give birth to children = self-sacrifice. The process of female pregnancy is not as idyllic as described in literary works. In fact, it is a process in which mother and fetus compete for survival resources.
No matter how much a pregnant woman loves her baby subjectively, the body will still regard this fetus as a "foreign body". This "foreign body" is absorbing nutrients from the woman's own body and becoming a burden to the body.
Therefore, generally speaking, the female body will do everything possible to expel this "foreign body" from the body, and the fetus will continue to maintain itself in the mother's stomach through a series of functions.
Mothers and fetuses compete for balance. With the increase of pregnancy, this balance is gradually unstable, and finally delivery begins and the baby is excreted.
Therefore, it is precisely because of this "struggle" that when you only look at the process of pregnancy and childbirth from the perspective of mother's health, after weighing the short-term and long-term advantages and disadvantages, you will find that the impact of childbirth on women must be more harmful than beneficial; In order to give birth to this child, mothers have to take more risks.
The greatness of a mother not only means the selfless love for her children in the future, but actually this love has started from the moment she was pregnant.
Therefore, don't try to persuade people to get pregnant and have children from the perspective of benefiting women's health.
For women, their pregnancy, childbirth, breastfeeding and parenting are all a kind of sacrifice and a kind of pay. Don't always think, "well, having a baby is actually good for your health, and your efforts can be rewarded with health." Even from a scientific point of view, this idea is untenable.
Pregnancy and childbirth are beyond the scope of health medicine and are a social problem. To put it bluntly, it is no exaggeration for women to sacrifice themselves for the continuation of mankind.
So, dads, give your mother more love. If you don't take good care of the woman who gave birth to your child, you will be struck by lightning.
