why do stillbirths happen at full term

A large proportion of stillbirths happen in otherwise healthy babies, and the reason often can't be explained. But there are some causes we do know about. Many stillbirths are linked to complications with the placenta. The placenta is the organ that links the baby's blood supply to the mother's and nourishes the baby in the womb. If there have been problems with the placenta, stillborn babies are usually born perfectly formed, although often small. With more research, it's hoped that placental causes may be better understood, leading to improved detection and better care for these babies. Вв a condition that causesВ a problem with the umbilical cord,Вwhich attaches the placenta to the baby's tummy button в the cord can slip down through the entrance of the womb before the baby is born (cord prolapse) or can be wrapped around the baby and become knottedВ

These bacteria include, klebsiella, enterococcus, Haemophilus influenza, chlamydia, and mycoplasma or ureaplasma. Some bacterial infections, such as and mycoplasma or ureaplasma, which are, can be prevented by using during sex.

Every baby is different and should grow to the size that's normal for them. Some babies are naturally small, but all babies should continue to grow steadily throughout pregnancy. If a baby is smaller than expected or their growth pattern tails off as the pregnancy continues, it may be because the placenta isn't working properly. This increases the risk of stillbirth.

Problems with a baby's growth should be picked up during antenatal appointments. It's important to be aware of your baby's movements and know what's normal for your baby. Tell your midwife immediately if you notice the baby's movements slowing down or stopping. Don't wait until the next day. See for more information. Stillbirth refers to the delivery of an infant who died in the uterus. The American Pregnancy Association points out that this term is only used for infant deaths that take place after the 20th week of pregnancy. Only one in 200 pregnancies end with stillbirth. In some cases, the death of the baby can occur during full-term labor and delivery. An autopsy of the baby's body can help reveal the cause of death. There are many possible causes. The placenta provides oxygen and nutrients to the unborn baby from the mother. If anything disrupts the flow, the baby can die. Sometimes there are no signs that this has occurred. Specific placenta problems include the detaching of the placenta from the uterine wall (placental abruption) or high blood pressure (preeclampsia). It is also possible for the placenta to fail to deliver adequate life support to the unborn child for no easily identifiable reason.

In about 15 to 20 percent of stillbirth cases, the infant has a birth defect, states March of Dimes. Birth defects that can lead to stillbirth include genetic chromosomal disorders or environmental defects. Any form of birth defect can cause the baby's body not to carry out normal life processes. A mother's body will deliver the baby if it dies in the womb. An infant who is too small or growing at an inadequate rate can die from a lack of oxygen. This can occur during birth or before birth. The cause is not usually known, but March of Dimes says that mothers who smoke put their babies at a heightened risk of death before delivery. Continued prenatal care can often identify growth problems. There isn't always something that can be done to improve a baby's growth in these situations. A late-term baby can be delivered via cesarean section in the hope that medical intervention will be successful. A bacterial infection that occurs between the 24th and 27th week of pregnancy can cause stillbirth, states American Pregnancy. The mother may not even notice an infection until the situation becomes serious. At this point, complications may have already impacted the baby. Examples of such infections include genital and urinary tract infections.
