Initially, a complete molar pregnancy develops like a normal one. Some of the earliest signs and symptoms that may indicate a complete molar pregnancy include:
Any of these symptoms are cause for concern and warrants an immediate visit to the doctor. Further examination may reveal other symptoms such as:
An abnormally fertilized egg is what causes a molar pregnancy. A normal human cell contains 23 pairs of chromosomes with each pair containing one chromosome from the father and one chromosome from the mother. A complete molar pregnancy occurs when all the chromosomes in the fertilized egg are the father's. This happens shortly after fertilization, when the mother's chromosomes are lost and the father's chromosomes get duplicated. There may be an inactive nucleus or no nucleus at all in the fertilized egg.
Complete molar pregnancies are a relatively rare occurrence. Some of the risk factors associated with complete molar pregnancies include:
Age of the mother – Women over the age of 35 years or under the age of 20 years are at a higher risk
Prior history of molar pregnancy – Women who have had a molar pregnancy previously are much more likely to have another
Ethnicity – Southeast Asian women have a higher risk of molar pregnancy
Women with a history of miscarriage
Your doctor may order some additional tests if he or she suspects a molar pregnancy. These include:
Molar pregnancies cannot be allowed to continue as a normal pregnancy. To avoid complications it must be terminated by the removal of the molar tissue.
The tissue will be removed by your doctor using a process known as dilation and curettage (D&C). The procedure will be performed in a hospital using general or local anesthesia and takes from 15 to 30 minutes. The uterine tissue is removed using a vacuum device.
In cases of extensive molar tissue and if no further pregnancies are contemplated, the doctor may recommend the complete removal of the uterus.
If HCG levels in your blood are still high after the D&C then you may require additional treatment. Your HCG levels will be monitored regularly for up to 1 year to ensure that there is no molar tissue left over from the D&C. Your doctor will recommend that you do not attempt to conceive again for that duration.
