Recurring abortions or multiple abortions: causes and news

Polyabortion affects thousands of couples worldwide and research is constantly underway. Miscarriages are frequent events, defined as such when they occur within 20 weeks of pregnancy, and they happen much more often than one might imagine. Little is said about it almost as if it were a sort of taboo and for this reason those who suffer from it live the experience closed in their shell when instead it is very important to talk about it , to find not only support but also solutions that come from the experiences of others.

The frequency of abortions

For women of childbearing age, the odds of having a miscarriage can range from 10 to 25%.

The probability of miscarriage increases with the woman’s age:

  • Women under the age of 35 have about a 15% chance of experiencing a miscarriage.
  • Women who are between the ages of 35 and 45 have a 20-35% chance of having a miscarriage.
  • Women over the age of 45 may have up to a 50% chance of experiencing a miscarriage
  • A woman who has had a previous miscarriage has a 25% chance of having another (this is only a slightly increased risk compared to those who have not had a previous miscarriage).

More than 90 percent of miscarriages that occur in the first trimester of pregnancy are caused by a genetic abnormality in the embryo that prevents it from developing.

Differences

Abortions are a form of natural selection: if a fetus has genetic problems that are incompatible with life, nature stops the growth of the fetus.

There are other causes of miscarriage that are related to either a malfunction of the toroids, poorly controlled diabetes or blood clotting disorders, but these cases are rarer.

Miscarriage can occur shortly after the delay and even before the fetus develops. In these cases we speak of biochemical pregnancy . The pregnancy test is positive but menstruation begins shortly after and the test becomes negative soon after.

Another form of miscarriage is called an anembryonic pregnancy or clear egg . In this case the pregnancy stops evolving after the gestational chamber has formed. On the other hand, when a fetus is seen with a heartbeat and at the next visit the heartbeat is no longer there, we start of intrauterine fetal death.

I want to reassure you that if the ultrasound shows a fetus with a heartbeat, the likelihood of miscarriage decreases significantly. If you then get to 12 weeks with a healthy baby, the miscarriage rate drops even more. This is why many people wait to break the pregnancy news until after 12 weeks.

This is a personal choice. I don’t think you have to wait 12 weeks to tell family and friends about your pregnancy especially if you are excited about the news. A small group of close people who, in the event of an abortion, can help support the mourning couple can first be said.

Recent studies indicate that it is no longer necessary to wait many months before trying to get pregnant again . This is because it seems that fertility is maximum within 6 months of the abortion.

However, if it is a question of repeated abortions it is good to do some in-depth checks to find the causes that determine them and then run for cover

Repeated abortions

Recurrent abortions have always been defined as the recurrence of 3 or more successive abortions. Recently, however, they have been re-defined starting from two or more spontaneous terminations of pregnancy.

The causes of polyabortion

They are very similar to those of single abortions.

Most miscarriages are caused by chromosomal or genetic abnormalities and these abnormalities are usually random events (unless one of the parents is a carrier). The anomaly can arise from the egg or sperm cell or form in the embryo.

The mother’s age plays an important role. The taller she is, the more likely she is to have repeated miscarriages. This is due to the poor quality of the eggs that carry chromosomal (genetic) abnormalities. .

Abnormalities of the uterus that cause miscarriage can also be a cause . Some women may be born with an irregularly shaped uterus, and some women may develop uterine abnormalities over time.

Miscarriage can also be caused by inflammation and infection.

A woman’s immune system may also  play a role in pregnancy loss as can  hormonal abnormalities including thyroid disease and diabetes.

Abnormalities in the mother ‘s blood clotting can lead to termination of pregnancy.

Environmental factors, stress and occupational factors do not appear to be related to repeated miscarriages.

Research news

According to scientists at Warwick University, a cause of recurrent miscarriages is to be found in the endometrium. In fact, researchers have found   a stem cell deficiency at the level of the uterine lining in women subject to multiple abortions and this could be the cause of accelerated aging of the endometrium which results in failed pregnancies.

The idea therefore is to develop strategies to increase the functionality of the stem cells of the uterine lining.

It is also essential to develop diagnostic systems (as they are already doing) to improve the screening of women at risk of recurrent miscarriage through the development of new endometrial tests.

Treatment instead is focusing on the use of drugs already used to help embryos implant more successfully in assisted reproduction treatments and which have the potential to increase stem cell populations in the lining of the uterus.

Obstetricians provide care to women during pregnancy, labor, and delivery, while gynecologists focus on the health of the female reproductive system, including the ovaries, uterus, vagina, and breasts. OB/GYN doctors are trained to provide medical and surgical care for a wide range of conditions related to women's reproductive health.
