Understanding Stillbirth -- the Basics In about half of all cases, the cause of stillbirth is unknown. The causes of a stillbirth that are understood include: 1  Birth defects, with or without a chromosomal abnormality.  Problems with the umbilical cord. With a prolapsed umbilical cord, the cord comes out of the vagina before the baby, blocking the oxygen supply before the baby can breathe on its own.

Causes This means that for some reason the placenta (the organ that links the baby's blood supply to the mother's and nourishes the baby in the womb) isn't functioning properly. A poorly functioning placenta may be the direct cause of stillbirth, or it may contribute to it because the baby's growth has been held back.

4 Common Causes of Miscarriage Cause No. 2: Medical Conditions. A miscarriage during weeks 13 through 24, the second trimester, often results from a problem with the mother. These are some health problems that increase a woman's risk for miscarriage. 1  An infection such as cytomegalovirus or German measles. 2  Hormone problems that prevent the lining of your uterus from thickening, which the fertilized egg needs to implant.

- Why Do Miscarriages Happen? The most common cause of pregnancy loss is a problem with the chromosomes that would make it impossible for the fetus to develop normally. Other factors that could contribute to a miscarriage include: abnormal hormone levels in the mother, such as thyroid hormone; uncontrolled diabetes

What Causes Premature Birth? Causes of premature birth can be split into main three categories -- birth where labor happens on its own, birth where mom's water breaks early, or birth when doctors decide that delivering the baby is medically necessary.

What Are the Most Common Stillbirth Causes? Just as chromosomal abnormalities cause the majority of miscarriages, certain chromosomal problems and birth defects can increase the risk that a baby will be stillborn. According to the March of Dimes, birth defects are a factor in about 14 percent of stillbirths.

First Trimester Miscarriage: How Common Is It And What's The Cause? Most of the time, a specific cause for miscarriage cannot be identified, though up to 70 percent of first-trimester miscarriages, and 20 percent of second-trimester miscarriages, are caused by chromosomal anomalies. Other possible causes could include infection or exposure to environmental or industrial toxins.

Ectopic Pregnancy Probably the most dangerous cause for bleeding during the 1st trimester is an ectopic pregnancy. Ectopic pregnancy occurs when your fertilized egg implants somewhere outside the uterus--usually the fallopian tube--and begins growing. (Ectopic means out of place.) Typically this happens if your fallopian tube is blocked by scar tissue or has an abnormality. Eventually the abnormal pregnancy will grow and could cause the tube to rupture; if this occurs, severe abdominal pain and bleeding will result. Most ectopic pregnancies are diagnosed in time to prevent this, but in the United States the condition still causes about 50 deaths a year.

- Stillbirth is when a baby is born dead after 24 weeks of pregnancy. The loss of a baby before the 24th week of pregnancy is called a miscarriage. Stillbirth is surprisingly common affecting around 1 in 200 pregnancies in the UK. The reasons for a stillbirth are not always known. Many women who have a stillbirth will be able to have a healthy baby in their next pregnancy.

Birth Injury Causes Understanding Birth Injury Causes. There are numerous types of birth injury causes, not all of which occur during childbirth. Some birth injuries are caused by a maternal infection that goes undiagnosed and untreated. Others include a delayed birth and oxygen deprivation before or during childbirth.

Brain injury in newborns could have many causes Brain injury in newborns could have many causes. It was long assumed that brain injuries in newborns resulted from insufficient oxygen during labor or delivery. Distressed parents often blamed doctors, a belief that spawned countless malpractice suits and prompted many obstetrician-gynecologists to abandon the delivery room.

Acquired Causes of Blood Clots The most common cause of maternal death in pregnancy is a blood clot, with an incidence of 1 to 5 per 1,000 pregnancies, including the time period after childbirth.

What causes stillbirth? Some babies die in the uterus (womb) before they are born (called an intra-uterine fetal death). It can happen during the last half of pregnancy or, more rarely, during the labour and birth, when it is known as intrapartum death. When the baby who has died during labour and birth is born, this is called a stillbirth. If a baby is born alive, but dies in the first 4 weeks of life, this is called a neonatal death. In South Australia, these deaths happen in less than 1 per cent of babies.

Preterm Labor - Cause Preterm labor can be caused by a problem involving the baby, the mother, or both. Often a combination of several factors is responsible. But in about 1 out of 3 preterm births, the cause isn't known. Causes of preterm labor include: Being pregnant with more than one baby. Women who are pregnant with more than one baby have an increased risk of complications-both for the mother and the babies-and typically deliver early.

Stillbirth What causes stillbirth? We don’t know what causes many stillbirths, but common causes include: Infections in the mother or baby. Some infections may not cause signs or symptoms and may not be diagnosed until they cause serious complications, like premature birth or stillbirth. Infections that can cause stillbirth include: Cytomegalovirus (also called CMV). This is a kind of herpes virus that you can get by coming in contact with body fluid (like saliva, semen, mucus, urine or blood) from a person who carries the virus. It’s a common infection in young children, but if you get it during pregnancy, it can cause serious problems, like stillbirth. Fifth disease. This is a common childhood illness that’s caused by a virus called parvovirus B19.

- The most common causes of sudden death are congenital abnormalities of the heart and blood vessels, or those that are present at birth. These abnormalities usually produce no symptoms and are disproportionately prevalent in African-American athletes.

Bleeding During Pregnancy (Light, Heavy, Causes, Pictures) Bleeding from an ectopic pregnancy is the most dangerous cause of first trimester bleeding. An ectopic pregnancy occurs when the fertilized egg implants outside of the uterus, most often in the Fallopian tube. As the fertilized egg grows, it can rupture the Fallopian tube and cause life-threatening bleeding.

Causes and Prevention of Premature Birth However, about fifty percent of the time, the cause or causes of a premature birth are unknown. When the cause is known, premature birth most frequently comes as a result of a premature rupture of the fetal membranes which initiates labour. Certain events can stimulate the onset of premature labour. These include: placental abruption, where the placenta separates from the uterus during pregnancy.
