Sharon Stone shares that she “lost 9 children” through an abortion

It is highly unlikely that you will ever know the true cause of a one-time miscarriage, but most of it is due to the following issues:

abnormal fetus

The most common cause of miscarriages in the first two months is a one-time abnormal fetal development, often due to chromosomal abnormalities. “It’s not like the baby is fine one minute and then suddenly dies the next,” says Professor James Walker, Professor of Obstetrics and Gynecology at the University of Leeds.

“These pregnancies fail from the start and are never destined to succeed.” Most miscarriages like this happen before eight weeks, although bleeding may not start until three or four weeks later, which is worth remembering for later pregnancies. “If the scan at eight weeks shows a healthy heartbeat, you have a 95% chance of a successful pregnancy,” says Professor Walker.

hormonal factors

A hormonal point can cause an intermittent miscarriage and it will never be a problem again. However, a few women who have long cycles and irregular cycles may experience recurrent miscarriages because the uterine lining is very thin, which makes implantation difficult.

Unfortunately, hormone therapy is not terribly successful.

Professor Walker warns: “There has been a trend for progesterone therapy, but trials show that this doesn’t really work.” “There is some evidence that injections of human chorionic gonadotropin, a hormone released early in pregnancy) can help, but it is not the answer for everyone. Treatment should begin as soon as pregnancy is confirmed, at about four or five weeks.


For women over the age of 40, one in four women experience a miscarriage. [One in four women of all ages miscarry, but these figures include women who don’t know that they are pregnant. Of women who do know that they’re pregnant, the figure is one in six. Once you’re over 40, and know that you’re pregnant, the figure rises to one in four]

Autoimmune blood disorders

About 20 percent of recurrent miscarriages have lupus or a similar autoimmune disorder that causes blood clots to form in the developing placenta.

A simple blood test, which may need to be repeated several times, can reveal whether or not this is the problem. ‘One negative test doesn’t mean a woman is fine,’ warns Roy Farquharson, a consultant gynecologist who manages early pregnancy. unit at Liverpool Women’s Hospital.

Pregnancy is often the cause of these disorders, so the test should be done as soon as possible, but it can easily be treated with low-dose aspirin or heparin injections, which help thin the blood and prevent blood clots from forming. – Recent experience has also shown that women perform equally well. “We have a 70 percent live birth rate in women treated for these disorders, which is excellent,” says Dr. Farquharson.

other reasons

While uterine abnormalities, such as fibroids, can cause a miscarriage, many women do not have problems conceiving until the end of the pregnancy. Cervical insufficiency can also cause a miscarriage at around 20 weeks.

While this can be treated with a special stitch in the cervix, trials indicate that it is not particularly successful, although it may delay labor for a few weeks. Few couples.

A procedure known as preimplantation genetic diagnosis can help. After in vitro fertilization (IVF), a single cell is taken from the developing embryo and tested for an abnormality in the gene. Then only healthy embryos are replaced in the womb.

It’s an expensive and cumbersome procedure – and pregnancy rates tend to be very low – but for some this is preferred over repeated miscarriages or a genetically abnormal baby.
