What Is a Molar Pregnancy?

A molar pregnancy, also called a hydatidiform mole, is a rare condition in which abnormal cells grow in the uterus instead of a healthy pregnancy. It is a type of gestational trophoblastic disease. In a complete molar pregnancy, no embryo forms, while in a partial molar pregnancy, an abnormal embryo may start to develop but cannot survive. Molar pregnancies are not viable and require treatment, but with proper follow-up most women recover fully.

Symptoms and Diagnosis

Symptoms can include vaginal bleeding, severe morning sickness, a larger-than-expected uterus for your dates, and sometimes passing grape-like cysts from the vagina. However, some molar pregnancies are found at a routine scan before symptoms appear. Diagnosis is usually confirmed by ultrasound and blood tests measuring hCG levels, which are often higher than expected. If a molar pregnancy is suspected, your care team will arrange prompt assessment.

Treatment and Follow-Up

Treatment involves removing the abnormal tissue from the uterus, usually through a minor surgical procedure called evacuation. In some cases, medication may be used instead. After treatment, follow-up is essential because in a small number of cases the abnormal cells can persist or return and require further treatment, sometimes with chemotherapy. You will be monitored through regular blood or urine hCG tests, usually for about six months, until levels return to normal.

Emotional Impact and Future Pregnancies

A molar pregnancy can be emotionally difficult, especially as it is often unexpected. You may need time to process both the physical recovery and the loss itself. Support from your care team, partner, and counselling services can help. It is important to avoid pregnancy during the follow-up period so that hCG monitoring is accurate. Once your levels are normal and you have the all-clear, most women go on to have healthy pregnancies. Your team will advise when it is safe to try again.
