There are many reasons for miscarriages. Some reasons are known, but some are still unknown. The known reasons are:
1) Chromosomal abnormalities
A large number of miscarriages occur due to chromosomal abnormalities in the fetus. This means that there is something wrong with the fetal chromosomes that leads to the death of the fetus.
2) Hormonal imbalances
Miscarriages can also be caused by hormonal imbalances in the mother’s body. For example, if the mother has too much or too little of certain hormones, this can lead to a miscarriage.
3) Problems with the uterus
A problem with the uterus can also cause miscarriages. For example, if the mother has a septum in her uterus, this can lead to a miscarriage because it blocks the passage of nutrients and oxygen to the fetus.
4) Problems with the cervix
Another possible reason is if there is something wrong with the cervical canal or cervix.
This could prevent the fetus from getting the nutrients and oxygen it needs to survive.
Infections can also cause miscarriages. For example, a urinary tract infection can travel up to the uterus and cause a miscarriage.
6) Other health conditions
Other health conditions can lead to miscarriages. For example, if the mother has diabetes, this can lead to miscarriages.
7) Excessive alcohol use by the mother
There is evidence that excessive alcohol intake during the first trimester of pregnancy causes an increased risk for miscarriage.
During pregnancy by the mother or second-hand smoking exposure might increase the risk of miscarriage.
9) Exposure to certain chemicals
Some studies indicate exposure to high levels of certain chemicals can increase the risk of miscarriages. Some examples are pesticides, herbicides, etc.
10) Idiopathic causes
It has been found that some cases of early pregnancy loss remain unexplained even after extensive testing. This is called the idiopathic cause of miscarriage.
Although the majority of miscarriages occur due to one or more of the above-mentioned reasons, it is important to remember that many pregnancies still result in healthy babies, even after a miscarriage has occurred. Most couples who have experienced a miscarriage go on to have healthy babies later on.
However, if you have had a miscarriage and are concerned about your future fertility or want to try for another baby, it is best to consult with your doctor. He or she can help you assess your risk and give you advice on what steps you can take to increase your chances of having a healthy pregnancy.
Understanding your risk is important as it can help you make the appropriate decisions regarding trying for another pregnancy.
For example, if you have had 3 miscarriages in a row, then your doctor will be more likely to recommend that you wait at least six months or even a year before getting pregnant again. This is because of your increased risk of having another miscarriage.
On the other hand, if you have had a history of miscarriages but none in the last year or more, then your doctor may recommend that you wait only 2 to 3 months before getting pregnant again.
