The hazards of anemia in pregnant women
Firstly, the occurrence of anemia during pregnancy is very common, and most cases are mild anemia, but a small proportion can be severe. The harm of anemia comes from two aspects: one is that it is harmful to the fetus, as anemia during pregnancy can affect the intellectual development of the fetus, which is very clear. Another harm comes from the mother, such as the possibility of postpartum hemorrhage or infection. If a cesarean section is performed, our hemoglobin must not be lower than 80 grams. If it is below 80 grams, a blood transfusion or intraoperative blood preparation is needed.
What is the earliest gestational week that a premature baby can survive?
Preterm infants, how many weeks can survive, first let's talk about the concept of preterm birth. The concept of preterm birth is more than 28 weeks but less than 37 weeks, this is called premature birth. However, with the improvement of neonatal resuscitation technology, in China, if it’s after 26 weeks, the vast majority of newborns can also survive. But after survival, the cost is quite high. For instance, if it's in a top-tier hospital, the cost for newborns born between 26 and 28 weeks can be around several hundred thousand yuan. So, even after some medical insurance policy reimbursements, you would still have to spend around tens of thousands of yuan on your own.
The difference between postpartum hemorrhage and menstruation
The difference between postpartum hemorrhage and menstruation varies whether it is a vaginal delivery or a cesarean section. The timing of postpartum bleeding varies, and it also relates to postpartum lochia. If the bleeding occurs within 24 hours, it is called severe postpartum hemorrhage; most frequently, we encounter bleeding after 24 hours. Typically, for vaginal deliveries, bleeding occurs within seven days. In cesarean sections, due to the uterine incision, healing is needed, and the duration of bleeding varies by individual and health, commonly lasting from one to two months post-operation. Postpartum bleeding is due to incomplete healing of the uterine lining, which is different from menstrual bleeding. Menstrual bleeding is usually heavier in the initial days and the blood is dark red with a cyclic pattern. In contrast, postpartum bleeding does not have a cyclic nature; it usually consists of fresh red or dark blood, whereas menstrual bleeding typically involves dark blood.
Does ovarian teratoma affect pregnancy?
In gynecology, teratomas are a very common type of ovarian cyst. If a teratoma is discovered during the pre-pregnancy period, its size should be considered. If the teratoma is larger than five centimeters in diameter and is accompanied by abnormalities on a CT scan, it is recommended to undergo surgery before attempting to conceive. If the teratoma is very small, such as two to three centimeters in diameter, it does not affect future pregnancy. If a teratoma is discovered during early pregnancy, opinions vary. Some recommend surgical treatment after the first trimester, while others suggest a pregnancy observation plan. Teratomas during pregnancy are prone to complications such as ovarian cyst torsion, which can cause abdominal pain. Therefore, if you have a teratoma and successfully conceive, be mindful of any pain.
Does a natural miscarriage count as an abortion?
Is miscarriage considered the same as abortion? These are not the same concepts, but they share similarities. Miscarriage is due to factors related to the mother or fetus, leading to the natural loss of the embryo, whereas abortion involves artificially inducing the removal of the embryo from the womb. Although miscarriages might also result in some postpartum complications, abortions tend to have more complications due to the artificial means involved. These artificial ways include surgical abortion procedures, during which there might be risks of infection and damage to the uterine lining.
Premature rupture of membranes causes
The causes of premature rupture of membranes, or premature rupture of membranes, occur before labor when the membranes break. Normally, the membranes should rupture during labor when the cervix is fully dilated. Any rupture before this is called premature rupture of membranes. The main causes of premature rupture of membranes are maternal infections or cephalopelvic disproportion. Infections can cause the membranes to become fragile and thin, and movements afterwards may lead to premature rupture. Another scenario is cephalopelvic disproportion, where the fetus is relatively large and the pelvis is small, leading to changes in amniotic fluid pressure, which can also result in premature rupture of membranes.
Is a posterior placenta more likely to lead to premature birth?
The placenta is divided into anterior and posterior walls, with the posterior wall being a normal location for the placenta, which is unrelated [to preterm birth]. Generally, there is a hereditary tendency for preterm birth, and it is more likely to occur in individuals with certain physical constitutions or in cases of twin pregnancies. Additionally, people with gestational diabetes are also prone to preterm birth. Therefore, the posterior wall of the placenta has no correlation with preterm birth. Conditions like placenta previa or premature placental detachment are placental positions that can lead to preterm birth issues, and some people may experience preterm birth under these circumstances.
What not to eat after a miscarriage
After a natural miscarriage, some people may become very weak. In such cases, it is important to consume mild and easily digestible foods. Foods that should be avoided are those that promote blood circulation, such as jujube. Drinking brown sugar water is advisable as it can help contract the uterus. Miscarriage can cause minor physical trauma or damage, so during this period, avoid consuming too cold or too spicy foods. Eating such foods may exacerbate abdominal pain or lead to infections.
Can endometriosis turn into cancer?
The answer is no. First, let's explain what endometriosis is. Endometriosis is when the endometrium, or the lining of the uterus, is found outside of its normal location, including in the muscular layer of the uterus, the ovaries, the pelvic cavity, or the intestines; it can occur in any of these areas. This condition is known as endometriosis. Endometriosis within the uterus is a benign condition, but it can lead to severe painful menstruation and chocolate cysts. If the menstrual pain is very severe, there may be a possibility of needing a hysterectomy in the future. If a chocolate cyst occurs, surgery might also be necessary.
What are the reasons for two instances of embryonic arrest?
According to current medical viewpoints, there are various reasons for embryonic arrest, but in 50% of cases, the cause is unknown. Identified causes can generally be divided into several categories such as chromosomal issues, maternal metabolic issues including thyroid disorders, diabetes, and polycystic ovary syndrome. Additionally, immune factors such as lupus erythematosus or Sjögren's syndrome, along with abnormal antibodies, are also reasons. Furthermore, abnormal maternal anatomical structures, like abnormal uterine development, can lead to embryonic arrest. Paternal factors, such as abnormal sperm, can also result in embryonic arrest. Upon encountering embryonic arrest, if it occurs once, it can be observed initially. However, if there are two or more instances, comprehensive examinations for both partners are necessary, including chromosomal tests.
