Causes of Sporadic Miscarriages and One-Time Pregnancy Losses
Reasons for Miscarriage
It's not easy to identify the reason for a miscarriage. In many cases, the cause may never be found. Most first trimester miscarriages occur because of chromosomal abnormalities, but some may also occur due to infections, chronic health conditions, or unexplained reasons.
Ectopic Pregnancy – What It Is and Why It Happens
Ectopic pregnancies happen when a fertilized egg implants someplace other than in the uterus, such as the fallopian tubes. Sometimes risk factors exist but other times the cause is unknown. Symptoms include severe abdominal cramping and dizziness.
What Causes Second Trimester Miscarriages?
Late miscarriages, such as those in the second trimester, can happen for a number of reasons. Causes might be chromosomal abnormalities, cervical insufficiency, congenital birth defects, placental problems, or other factors.
Why Do Chromosomal Abnormalities Cause Miscarriage and Stillbirth?
Miscarriages are usually blamed on chromosomal abnormalities, but why exactly do problems in the chromosomes lead to miscarriage in some cases while babies can be born with chromosomal disorders in other cases? Researchers aren't 100% sure.
What Causes Chemical Pregnancies?
Doctors do not know exactly what causes chemical pregnancies (very early miscarriages), but most suspect that the cause is a chromosomal problem in the sperm or egg that leads to the pregnancy failing to implant properly.
Can falling during pregnancy cause a miscarriage?
Even though it happens in movies, falling down during the first trimester is not likely to cause a miscarriage. A fall or other physical trauma, such as a car accident in the second or third trimester, however, could cause pregnancy loss.
Vanishing Twin Syndrome - Loss of One Baby in a Multiple Pregnancy
Vanishing twin syndrome is a condition in which one baby is lost and reabsorbed by the mother's body early along in a multiple pregnancy. Parents who experience vanishing twin syndrome may simultaneously grieve the miscarriage of the lost multiple while also feeling relief that the pregnancy is still otherwise viable.
Understanding Blighted Ovum
A blighted ovum is a miscarriage in which the baby does not develop, but a gestational sac continues to grow and the woman may continue to experience pregnancy symptoms. A blighted ovum can be a missed miscarriage treated via D & C or may end naturally.
Understanding Molar Pregnancy – What the Terms Mean
Molar pregnancy can be really confusing, involving a lot of unfamiliar terms like hydatidiform mole, gestational trophoblastic disease, and more. Learn what all the terms mean.
Chemical Pregnancy - A Very Early Miscarriage
Despite the name, a chemical pregnancy is not a false pregnancy or a false positive on a pregnancy test -- it is a very early miscarriage. Doctors believe chemical pregnancies are usually caused by chromosomal abnormalities.
What Causes Chromosomal Abnormalities That Lead to Miscarriage and Stillbirth?
According to research, random chromosomal abnormalities are the culprit in most miscarriages and in many stillbirths. But what causes the chromosomal abnormalities themselves? Parental age is one risk factor but evidence is mixed on others.
Chromosomal Abnormalities - March of Dimes
This March of Dimes fact sheet describes the underlying basics of how chromosomal abnormalities can affect a baby in a miscarriage and how chromosome issues cause other disorders that may be detected after giving birth.
Bacterial Vaginosis and Miscarriages
A 2003 study by researchers at the St. George's Hospital in London found that treating women for bacterial vaginosis could reduce the risk of miscarriage and premature birth, contributing to the notion that bacterial vaginosis may increase miscarriage risks.
