Symptoms and Treatment of Partial Molar Pregnancy

Partial molar pregnancy can manifest through various symptoms, indicating the presence of abnormal placental tissue. Recognizing these signs is important for seeking timely medical attention. Additionally, understanding the available treatment options is essential for managing this condition effectively. Let’s explore the symptoms and treatment of partial molar pregnancy in detail.

Symptoms of Partial Molar Pregnancy

The symptoms of partial molar pregnancy can vary from woman to woman. However, some common indicators may suggest the presence of this condition. It’s important to note that these symptoms can also resemble those of a normal pregnancy. Consulting a healthcare professional for accurate diagnosis is crucial. The following are some potential symptoms of partial molar pregnancy:

  • Vaginal bleeding: Bleeding during the first trimester of pregnancy, which can be lighter or heavier than normal.
  • Severe nausea and vomiting: Experiencing persistent and severe morning sickness beyond the first trimester.
  • Rapid uterine growth: The uterus growing at a faster rate than expected for the gestational age.
  • High blood pressure: Development of hypertension during pregnancy.
  • Excessive pelvic pressure: Feeling increased pressure or discomfort in the pelvic region.
  • Hyperthyroidism symptoms: Experiencing symptoms like weight loss, irritability, and an irregular heartbeat.

Treatment of Partial Molar Pregnancy

When partial molar pregnancy is diagnosed, prompt treatment is necessary to prevent complications and ensure the woman’s well-being. The primary treatment approach for partial molar pregnancy involves the following key steps:

  • Evacuation of the uterus: This procedure involves the removal of the abnormal placental tissue through suction dilation and curettage (D&C).
  • Monitoring of human chorionic gonadotropin (hCG) levels: Regular hCG blood tests are conducted to ensure that the levels return to normal after the evacuation. Elevated hCG levels post-treatment may indicate persistent molar tissue.
  • Follow-up care: After the treatment, close monitoring and follow-up visits are essential to ensure complete recovery and to detect any potential complications.

How to prevent Molar Pregnancy?

Molar pregnancies are typically caused by genetic abnormalities during fertilization. Unfortunately, there is no known way to prevent molar pregnancies, as the genetic abnormalities occur randomly and spontaneously. However, there are a few steps you can take to ensure early detection and appropriate management:

  • Regular prenatal care: Attend regular prenatal check-ups with your healthcare provider. They will monitor your pregnancy and detect any abnormalities or potential signs of a molar pregnancy.
  • Awareness of risk factors: Understand the risk factors associated with molar pregnancies, such as advanced maternal age (over 35), previous molar pregnancy, or a history of miscarriages. If you have any of these risk factors, your healthcare provider may provide closer monitoring.
  • Early detection: If you experience symptoms such as abnormal vaginal bleeding, severe nausea and vomiting, or a rapidly growing uterus, seek immediate medical attention. Early detection allows for prompt diagnosis and appropriate management.
  • Genetic counseling: If you have a history of molar pregnancies or other genetic abnormalities, consider genetic counseling before attempting pregnancy. A genetic counselor can provide information and guidance based on your specific circumstances.

What happens if a Partial Molar Pregnancy is not treated?

If a partial molar pregnancy is not treated, it can lead to various complications. A partial molar pregnancy occurs when abnormal placental tissue develops alongside an embryo that has severe abnormalities or is not viable.

If left untreated, a partial molar pregnancy can progress to a complete molar pregnancy, where the embryo does not develop at all and only abnormal placental tissue is present. This can result in a higher risk of complications such as excessive bleeding, infection, and the development of gestational trophoblastic disease (GTD).

GTD is a rare condition characterized by the abnormal growth of cells inside the uterus. It can lead to persistent or intermittent vaginal bleeding, an enlarged uterus, and other symptoms. In some cases, GTD can become cancerous, requiring more extensive treatment such as chemotherapy.

Therefore, it is crucial to seek medical attention and follow the recommended treatment for a partial molar pregnancy to minimize the risks and potential complications associated with the condition.

What is the best treatment for Partial Molar?

The best treatment for a partial molar pregnancy is typically a surgical procedure called dilation and curettage (D&C). This procedure involves removing the abnormal placental tissue from the uterus through dilation of the cervix and scraping of the uterine lining.

After the D&C, close monitoring of hCG (human chorionic gonadotropin) hormone levels is necessary to ensure they return to normal. Regular follow-up visits and blood tests are crucial to detect any signs of persistent or recurrent gestational trophoblastic disease (GTD).

In most cases, a D&C is sufficient to treat a partial molar pregnancy. However, if there are indications of persistent or invasive GTD or if the molar tissue is extensive, additional treatment such as chemotherapy may be necessary. Chemotherapy drugs like methotrexate or a combination of drugs can be used to treat GTD effectively.

Can Folic Acid prevent Molar Pregnancy?

No, folic acid supplementation does not prevent molar pregnancies. Molar pregnancies occur due to genetic abnormalities during fertilization and are unrelated to folic acid intake.

However, it is important for women of childbearing age, including those planning a pregnancy, to take folic acid supplements. Folic acid is known to help prevent certain birth defects of the baby’s brain and spine, such as neural tube defects. It is recommended that women take 400-800 micrograms of folic acid daily before conception and during early pregnancy.

While folic acid is beneficial for the healthy development of a baby, it does not have a preventive effect on molar pregnancies. Molar pregnancies are a complex genetic phenomenon that cannot be prevented through the intake of folic acid or any other specific nutrient.

Who are at risk for Molar Pregnancy?

Several factors can increase the risk of a molar pregnancy. Women who are at a higher risk for molar pregnancies include:

  • Age: Molar pregnancies are more common in women over the age of 35.
  • Previous molar pregnancy: Women who have previously had a molar pregnancy are at an increased risk of experiencing another molar pregnancy in future pregnancies.
  • History of miscarriage: Women who have a history of recurrent miscarriages may have a slightly higher risk of molar pregnancies.
  • Ethnicity: Women from certain ethnic backgrounds, such as women of Asian descent, have a slightly higher risk of molar pregnancies.
  • Nutritional factors: A diet lacking in certain nutrients, such as folic acid, may contribute to an increased risk of molar pregnancies, although the evidence is not conclusive.


Understanding the symptoms and treatment of partial molar pregnancy is essential for early detection and proper management. By recognizing the potential signs and seeking prompt medical attention, individuals can receive appropriate care to address this condition effectively. Treatment typically involves the evacuation of the abnormal placental tissue and close monitoring to ensure complete recovery. If you suspect any symptoms or have concerns, it is always advisable to consult a healthcare professional for accurate diagnosis and guidance.

Remember, early detection and timely intervention are key to ensuring the best possible outcome. Stay informed, prioritize your health, and reach out to medical professionals for any necessary support and guidance.

Frequently Asked Questions (FAQs)

Can a Partial Molar Pregnancy be misdiagnosed as a Normal Pregnancy?

Yes, partial molar pregnancy can sometimes be misdiagnosed as a normal pregnancy due to overlapping symptoms. Consulting a healthcare professional and undergoing appropriate diagnostic tests is crucial for accurate identification.

Are Partial Molar Pregnancies Hereditary?

No, partial molar pregnancies are not hereditary. They occur due to chromosomal abnormalities during fertilization.

Is it possible to have a healthy Pregnancy after experiencing a Partial Molar Pregnancy?

Yes, it is possible to have a healthy pregnancy after a partial molar pregnancy. However, close monitoring and follow-up care are important to ensure the successful progression of the subsequent pregnancy.

Are Partial Molar Pregnancies associated with an increased Risk of Cancer?
