What is a Blighted Ovum?
Causes
A blighted ovum is a form of abnormal pregnancy, and these are well-known causes:
- Poor quality of eggs or sperm that cannot further any development.
- Abnormalities of chromosomes in embryos. This can happen naturally and can occur at any age. As women are aging, they may have chromosomal abnormalities in fertilized eggs that lead to embryos with abnormal amounts of chromosomes. It could be less or more amount with a pair of chromosomes, or it could happen to many pairs at the same time.
Symptoms of a Blighted
In the beginning, women who have blighted ovums will feel completely normal as a regular pregnancy. Some might have stomach cramps or bleeding while others have no symptoms at all.
They will probably find out that they have blighted ovum when they go for regular ultrasounds and then see no developments in embryos.
Therefore, it can be very confusing and devastating to women who have to experience this. However, it is important for them to stay strong physically and emotionally and to remember that they can always try again.
In addition, blighted ovum can happen to any woman, and the placenta will produce HCG hormones as same as in normal pregnancy but at a lower level. Some women also do not have morning sickness and do not have any unusual symptoms.
Recurrent
Having repeated blighted ovum pregnancy will increase the risk of having abnormal chromosomes in embryos. Examination for the causes should be done when blighted ovum pregnancy occurs more than 2 times.
For example, one of the partners might have an abnormal position in chromosomes that will be passed to the baby, but we cannot find any symptoms in the bodies. This example is called balance translocation.
Treatment and Prevention
For treatment, the doctor will perform a procedure called dilation and curettage to remove the abnormal placental tissues.
For prevention, there is no medication to prevent this condition. The best ways to prepare for pregnancy and reduce the risk of having blighted ovum are eating healthy, exercising regularly, and getting enough sleep.
