Causes Of Repeated Miscarriages
When a woman miscarries, it is an extremely painful experience. Not only does the woman undergo physical trauma, she also has to face emotional trauma of losing her baby. While most women who have miscarriages will have healthy pregnancies and healthy babies, there are some who are faced with pain of repeated miscarriages. The American Society for Reproductive Medicine states that just 1 percent of pregnant women have 3 successive miscarriages or more. Such women often wonder what are the causes of these repeated miscarriages.
Usually, doctors wait for a woman to have 3 successive miscarriages in order to begin testing the causes. Unfortunately, many times, even after several tests it may be impossible for a doctor to figure out the cause of repeated miscarriages. Nonetheless, some causes of repeated miscarriages have been determined.
The most common cause is genetic defects. It is estimated that nearly 70 percent of miscarriages are due to genetic abnormalities. This type of abnormality is more prevalent in women who are more than 35 years of age. Also, it must be noted that genetic abnormalities are usually random and it is not necessary that they will occur in later pregnancies.
Abnormalities of the uterus are other reasons for repeated miscarriages. These abnormalities make it difficult for the fetus to attach to the uterus and as a result they are miscarried. Some of the abnormalities of the uterus can be corrected with the help of surgery.
Age also seems to have an effect on miscarriages. It has been seen that after a woman crosses the age of 35, the chances of miscarriage increase. And this possibility increases still further once the woman crosses the age of 40.
Hormone deficiency can also result in repeated miscarriages. This is especially true in the initial stages of pregnancy when progesterone is required to maintain the pregnancy. If progesterone levels are low, the woman will miscarry. However, this can be resolved by giving the woman supplements of progesterone.
Women suffering from polycystic ovarian syndrome tend to have repeated miscarriages, as the level of male hormones in their bodies is higher than female hormones.
Having a weak cervix can result in a miscarriage in the 2nd trimester. In such women, usually the doctor will suture the cervix to prevent premature dilation and reduce the chances of a miscarriage. This suturing is known as cerclage.
Another cause of repeated miscarriage is autoimmune disorder. Some of these disorders prevent adequate blood flow to the growing fetus, resulting in a miscarriage. At the moment, researchers are still trying to figure out how to treatautoimmune disorders that cause repeated miscarriages.
Women suffering from Type 1 diabetes are also prone to repeated miscarriages. Such women have to control their blood sugar levels before getting pregnant and during pregnancy to ensure that they have a healthy pregnancy.
