What causes a blighted ovum in pregnancy?

In general, a blighted ovum may be caused by environmental stimuli, abnormal sperm, chromosomal abnormalities, viral hepatitis, lupus erythematosus, and other factors. It is recommended to seek medical attention promptly to determine the underlying cause and receive appropriate treatment. Specific analyses are as follows:

1. Environmental stimuli

If a pregnant woman continues to be exposed to environments with high levels of radiation or harmful chemical substances, it may adversely affect embryonic development, leading to a blighted ovum. It is advised to avoid such adverse environments, ventilate indoor spaces regularly to maintain air circulation, and prevent further harm.

2. Abnormal sperm

Poor sperm motility or abnormal morphology may lead to poor development of the fertilized egg, resulting in a blighted ovum. Under medical guidance, medications such as vitamin E capsules, zinc gluconate tablets, and progesterone capsules may be used for treatment.

3. Chromosomal abnormalities

Usually caused by genetic mutations, an abnormal number of chromosomes in the fertilized egg may result in a blighted ovum. It is recommended to seek prompt medical care; in some cases, induced abortion may be necessary.

4. Viral hepatitis

This may be caused by infection with the hepatitis B virus. The disease can impair embryonic development, leading to the aforementioned condition, and may also present with symptoms such as jaundice and bradycardia. Under medical supervision, medications such as vitamin C tablets, vitamin B6 tablets, and vitamin B1 tablets may be prescribed for treatment.

5. Lupus erythematosus

This may result from genetic factors or autoimmune dysfunction. The condition can easily affect reproductive health during pregnancy, leading to the above symptoms, along with fever, fatigue, and other discomforts. Prompt medical consultation is recommended, with symptomatic medication administered under medical guidance.

During pregnancy, prenatal check-ups should be performed regularly as directed by a healthcare provider to monitor fetal development. Additionally, maintaining a positive mood and communicating frequently with family and friends is beneficial to minimize negative emotional impacts.
