- Recurring Miscarriages is a condition where a woman experiencing spontaneous abortion before the end of 22. weeks pregnant
- A number of factors such as being overweight, smoking, alcohol, malformations of the uterus and autoimmune diseases increases the risk
- Diagnosis consists of conversation, objective examination and chromosome study of paired and coagulation elucidation of the woman, after which there shall be an individual plan
- Additional immunological elucidation is a specialist task, which takes place at the national hospital’s fertility clinic
What is the repeated miscarriages?
Spontaneous abortion means loss of pregnancy without external intervention, said by legalarmist before the fetus has reached viability. All pregnancy loss from the time of fertilization to 22 weeks of pregnancy, therefore, belong under the concept of length miscarriage. Repeated miscarriages is defined as three or more miscarriages in a row.
Involuntary abortion – also called spontaneous abortion-unfortunately happens quite often. Between 25 and 30 couples find that one or more pregnancies ends with a miscarriage. Although 15% of all identified pregnancies ending in miscarriage, so the total number is estimated to be closer to 50%. Most of the undiscovered abortions happening so early in the pregnancy, the woman has not yet reached to discover that she is pregnant. In 10-12% of all pregnancies occur abortion so late that a foster facility can be accessed by an ultrasound scan. In these cases it is most often necessary with medical induction of abortion or a curettage.
How frequent is repeated miscarriages?
Barely 1% of all women miscarry three or more times in a row, and in these cases we are talking about abortus habitualis. Fortunately for most women succeed with abortus habitualis to get their wished-for child for a larger or smaller number of pregnancies. Unfortunately, there is also a smaller group that continues to abort in pregnancy after pregnancy. See more on loverists.
What is the reason for repeated miscarriages?
There can be many explanations that a pregnancy progresses to a miscarriage, but over half of the cases are due to chromosomal defects in the fetus. The process of making a child is complicated, and you encounter errors in inheritance installations easily. You could say that a miscarriage often is nature’s way to dispose of defective foetuses. The risk of chromosomal defects in the fetus rises, the older women, and at the same time, the risk is greater for spontaneous abortion.
Since miscarriages are so frequent, there are also some who just randomly have three miscarriages in a row. The biggest risk factor to abort is the woman’s age, and the risk of three miscarriages in a row increases the older the woman is. The man’s age has little or no effect on miscarriage risk.
The woman’s age and the risk of miscarriage:
In 19 years, 20-24 years 13% 11%, 25-29 years 30-34 years, 12%, 15%, 25%, 35-39 years 40-44 years 50%, over 45 years 93%
The chance to carry out a pregnancy also depends on the number of previous miscarriages.
For a young woman, who has not previously had a child, is the risk of a new abortion:
After no abortions 11%
After 1 miscarriage 15%
After 2 miscarriages 25%
After 3 miscarriages 45%
After 4 miscarriages 55%
A woman with three previous miscarriages and no children has 50-60% chance of having a baby in the next pregnancy. If the woman has previously given birth to a child, is the chance of another child in the next pregnancy 80%, according to petsinclude.
Generally, the greater the number of abortions it previously had, the older you are and the fewer normal pregnancies have been carried out, the greater the risk of a miscarriage.
What are the symptoms of repeated miscarriages?
Bleeding and pain as if by spontaneous abortion, but 3 or more times.
What symptoms you should pay particular attention to?
Bleeding and pain.
Why are there some who get repeated miscarriages?
The incidence of repeated spontaneous abortions (1%) is clearly higher than what would be expected by a mere coincidence, and it suggests that there may be an underlying cause. While the vast majority of miscarriages are caused by a chromosomal defects in the fetus, can also join, repeated abortions if the fetus has normal chromosomes.
Unfortunately, it is rarely possible to find a cause of abortus habitualis, and it is even harder to find a cause that we can do something about.
Malformation of the uterus
Malformations of the uterus, which can be of importance for abortus habitualis, found in about 5%. It can be about a septum in uterus or fibroids (fibroids). The uterus is examined with ultrasound scan, and the investigation may be supplemented with water scan, which introduced a little sterile saline into the uterine cavity or an endoscopy.
By more than three miscarriages, one can examine the fetal chromosomes. Since most sporadic abortions is due to a chromosomal defects in the fetus, are abnormal chromosomes is a good sign, suggesting that abortion is a coincidence. Is that normal chromosomes in the fetus, there is a higher risk for a second reason for abortion. Chromosome analysis of one or both parents is made by four abortions or more, or if there has also been an abortion in 2 trimester (between 12 and 22 weeks pregnant), or there is a familial predisposition for repeated abortions. The test shall be carried out on a sample of blood, where the chromosomes in the cells are counted, and their appearance is assessed. With approximately 5% of men/women with abortions habitualis has two chromosome pieces swapped space (called a translocation), and this can cause abortion in up to 50% of the couple’s pregnancies.
Some studies suggest that women with high concentration of the hormone LH in the blood early in the cycle and women with PCOS (polycystic ovarian syndrome), are at increased risk of miscarrying. Today one more think that the tendency to abort is linked to the onset of diabetes and obesity. In women with diabetes, there is increased risk of miscarrying, if sugar disease is poorly regulated, while a well-regulated diabetes does not result in increased miscarriage risk. The hormone progesterone is produced in the ovary after ovulation, and are in early pregnancy is necessary in order to maintain a pregnancy. For many years it was thought that for low formation of this hormone could be a cause of spontaneous abortion and abortus habitualis. A few cases of abortion is undoubtedly due to progesterone deficiency; but in the vast majority of cases, where one measures a low progesterone with a woman who later miscarry, this is probably the result of the fact that the fetus is not viable for other reasons. In General, there is no basis for treatment with progesterone in the case of repeated abortions.
Women with repeated miscarriages have specific antibodies in the blood, more often than women who have had children without problems. Some believe that these antibodies may cause abortion by harming placenta, while the other believe that the antibodies are merely a symptom of the fact that these women have a poorly regulated and aggressively for the immune system. It is difficult to measure the immune system, but the detection of autoantibodies can be followed up with additional studies.
The blood’s clotting ability
Changes in the blood’s clotting factors may have significance for abortus habitualis. Some of these changes are heritable, and is associated with increased risk of blood clots in the placenta, but also increased the risk of blood clots in the legs and lungs. Known predisposing factors for spontaneous abortion is smoking, alcohol abuse, coffee (over three cups daily) and overweight. The importance of these factors, however, is in all probability the message.
