An abortion commonly referred to as a “spontaneous abortion” describes the loss of a pregnancy, usually occurred during the first 20 weeks. About 80 percent of all abortions occur before completing the first trimester of pregnancy. Recent research shows that 10 to 20 percent of women who are aware of being pregnant suffer from abortion.
This percentage does not include situations in which a 30 to 50 percent of fertilized eggs are lost before even becoming pregnant, which happens very early to not even notice.
The causes of abortion are not always clear and precise.
The most common assumption of abortion that occurs during the first 12 weeks of pregnancy is related to hormonal problems, collagen vascular diseases (such as rheumatoid arthritis), infections, abnormalities in chromosomes, etc.
However, most abortions have been attributed to chromosomal abnormalities in the fetus. Each of the most common causes of abortion known will be discussed below.
- Hormonal problems.
Hyperthyroidism, Cushing’s disease and syndrome of the poly cystic ovary are all examples of hormonal problems that increase the possibility of having an abortion. Luteal phase defects, which means there is not enough progesterone produced to keep the fetus in the ovary is another possible cause of abortions that can lead to fetal loss, but the results of these studies are questionable.
- Chromosomal defects
Chromosomes are located in the nucleus of cells and are the result of a combination of proteins and DNA. These contribute significantly to determine the physical attributes of a person. Because the chromosomes are multiplied many times during fetal development, there is no precise way to say at what point the problem occurs. However, for couples who have a history of abortions, a genetic screening can determine the outcome of a pregnancy before it occurs.
In abortions that occur during the first 12 weeks, 50 percent of fetal tissue contains a chromosomal abnormality. As the pregnancy progresses, the percentage decreases by more than half. Abortions in the first trimester occur so frequently that are not considered “abnormal” at all unless the woman has a history of past abortions.
However, an abortion than occurs in the second quarter is not expected, and should conduct a thorough investigation. Chromosomal defects are more likely to occur as women age wins, and the likelihood of abortion in a woman at 40 years are immense.
- Abnormalities of the cervix or uterus
The uterus forms some women have irregular shapes, and this contributes to abortions. Some women suffer from a condition where the uterus is divided into separate sections by bridges tissues. The bridge called “pulp”, does not have a sustainable supply of blood and does not support embryo implantation. If the embryo cannot be implanted completely in the uterine wall, most cases simply are expelled from the uterus.
Fibroids, another cause of abortions, are benign tumors that form in the uterus and compromise its structure. Denominated leiomyoma, originate from abnormal muscle tissue in the uterus. In general, they do not cause abortions but can prevent the embryo from attaching to the uterus, which can compromise the blood supply of the embryo.
- Disorder of the immune system
Doctors do not agree in full if the immune system disorders are now a factor for an abortion to occur. They are investigating the matter. However, researches made by the American College of Obstetrics and Gynecology seem to suggest that autoimmune diseases increase the chance of having an abortion. Because the behavior of immune system diseases, in these cases it is thought that the body simply reject the pregnancy.
Many types of infections can lead to abortion. These infections are often transferred to the placenta and fetus, causing it to become unviable. Some infections are particularly dangerous for pregnancy, including herpes simplex, malaria, and syphilis. While viruses have a similar effect, extremely common infections in pregnancy will not affect the uterus unlike what many think.
- Common Diseases
There are some common diseases that are known to result in deformities or fetal loss, such as chicken pox or fifth disease if you have not suffered then previously and have not been vaccinated. You should consult with your doctor to confirm whether new or old antibodies are in your blood. Old antibodies are ideal.
If you develop a high fever, as over 101 degrees Fahrenheit, you should treat it immediately, and you should take a fever reducer such as Tylenol under the strict supervision of your doctor.
The natural process of aging is a risk factor for suffering an abortion. Everything in the body ages, including the sperm and the eggs it produces. So, the old a woman becomes, the greater the possibility of having a fetus with abnormalities and therefore suffering an abortion. Thus, a 40-year-old has double the chance of having an abortion than a woman of 20. Hormonal problems are more persistent when you get older, and chromosomal levels and quality are more likely to be affected.
- Health problems in the mother
If the mother suffers from a chronic illness or some other medical problem, the chance of abortion is much higher. Heart disease, thyroid problems, diabetes, hypertension, problems that can result in problems during pregnancy. However, this does not mean that you will definitely have an abortion, you simply must be careful and control these conditions with the help of your doctor.
The amniotic sac and the fluid it contains provide shelter and protection to the fetus, so common accidents do not have to result in abortions, particularly if the abdominal area is not seriously injured. Excluding the causes identified above, other causes of abortions are:
- Blood disorders, such as sickle-cell anemia, reduce the chance of pregnancy in all terms.
- Any Other heart disease that compromises your performance, circulatory system, liver or kidney functions, can cause abortions in later quarters.
- The Consumption of alcohol, caffeine, snuff and illegal substances dramatically increase the likelihood of spontaneous abortions.
- Your daily routine may be hazardous to your pregnancy, in the form of environmental hazards and in your workplace. These include inhalation of lead, carbon monoxide, and other chemicals, and radiation exposure.
How it is diagnosed and treated an abortion?
If you suspect the possibility of an abortion, see your doctor and he will perform a pelvic examination and / or ultrasound. This evaluation will determine the extent of the expulsion and when it will be complete. If the abortion is incomplete, he will have to dilate the cervix and manually remove all fetal and placental tissues. This simple procedure is called dilation and curettage. As an alternative, certain drugs can be administered to achieve the same effect.
