Blighted ovum

Definition

A blighted ovum, also known as an anembryonic pregnancy, is a type of early miscarriage where a fertilized egg implants into the uterus but a viable embryo does not subsequently develop. This typically results in an empty gestational sac, hence the term ‘blighted’. The body usually expels the pregnancy tissue on its own, but medical or surgical treatment may sometimes be needed.

Key Takeaways

1. A Blighted ovum, also known as an anembryonic pregnancy, occurs when a fertilized egg attaches itself to the uterine wall, but the embryo does not develop. Cells develop to form the pregnancy sac but not the embryo itself.
2. It is a common cause of early pregnancy loss, often occurring before a woman is even aware she is pregnant. The body typically expels the pregnancy naturally, resulting in what is known as a miscarriage.
3. It is usually detected via ultrasound which shows an empty gestational sac. Absence of expected embryonic development despite an enlarged gestational sac is considered a diagnosis of blighted ovum. Despite the loss, many individuals who have had a blighted ovum will go on to have successful pregnancies in the future.

Importance

The term “blighted ovum” is essential in the context of motherhood and reproductive health as it refers to a specific type of miscarriage that happens when a fertilized egg implants in the uterus but doesn’t develop into an embryo.

It is a serious concern for women trying to conceive because it accounts for about 50% of first trimester miscarriages and usually occurs so early that many women don’t even realize they’re pregnant.

Its identification can help medical professionals guide women towards necessary physical care and emotional support, as well as discuss potential future pregnancies.

Furthermore, understanding what a blighted ovum is can help demystify the complexities of pregnancy complications, ensuring women are better informed about their reproductive health.

Explanation

A blighted ovum, also known as an anembryonic pregnancy, refers to an early pregnancy condition where a fertilized egg implants into the uterus, but an embryo fails to develop. It is one of the primary causes of early pregnancy failures, usually within the first trimester.

Interestingly, despite the lack of embryonic development, the body continues to prepare for pregnancy, and pregnancy hormones are still produced, often leading to common pregnancy symptoms and a positive pregnancy test. The purpose of identifying a blighted ovum is to ensure the health and well-being of the woman.

Diagnosis is typically made through an early ultrasound that shows a gestational sac — the initial sign of a developing pregnancy within the uterus — but no embryo. This diagnosis can offer an explanation for bleeding, spotting, or cramping in early pregnancy, indications that may have led to a medical consultation in the first place.

Once diagnosed, the pregnancy can be medically managed to prevent complications such as infection or undue emotional distress. Understanding what a blighted ovum is can help to make sense of a complex and often distressing situation, enabling proper treatment and support.

Examples of Blighted ovum

A woman named Lisa experienced unusually heavy bleeding two weeks after confirming her pregnancy. Upon visiting her doctor, she underwent an ultrasound which revealed an empty gestational sac in her uterus. The diagnosis was a blighted ovum where an early embryo had stopped developing and was reabsorbed by the body before the scan.

Another example involves a couple, Emily and Scott. They were thrilled when they discovered Emily was pregnant after months of trying. However, at their first prenatal appointment, the ultrasound showed a gestational sac with no signs of an embryo. The doctor diagnosed the situation as a blighted ovum.

Jane is a third case. She had all the signs of early pregnancy – missed periods, nausea, and fatigue. However, her doctor couldn’t detect a heartbeat at what should have been six weeks. An ultrasound revealed a blighted ovum, where a fertilized egg had implanted in her uterus but the fetus did not develop. Jane underwent a dilation and curettage procedure to safely remove the tissue.

FAQs on Blighted Ovum

What is a blighted ovum?

A blighted ovum (also known as an ‘anembryonic pregnancy’) happens when a fertilized egg attaches itself to the uterine wall, but the embryo does not develop. Cells develop to form the pregnancy sac, but not the embryo itself.

What causes a blighted ovum?

A blighted ovum is caused by chromosomal abnormalities, which prevent the embryo from developing. Most commonly, it is not due to anything the mother has done.

What are the symptoms of a blighted ovum?

A blighted ovum often has no symptoms. Many women only discover they have a blighted ovum after an ultrasound confirms the absence of an embryo. Some might experience signs of early pregnancy, such as missed periods, breast tenderness, nausea, and vomiting.

What is the treatment for a blighted ovum?

The body will often recognize the pregnancy is not developing as it should and will naturally miscarry. However, in some cases, a procedure (D&C) may be necessary to remove the pregnancy tissues.

Can I get pregnant again after a blighted ovum?

Yes, having a blighted ovum does not reduce your chances of getting pregnant again or having a healthy pregnancy in the future. Many women go on to have successful pregnancies after a blighted ovum.
