Hydatidiform mole

Symptoms

What are the main symptoms of a hydatidiform mole?

Symptoms of a hydatidiform mole, or a molar pregnancy include:

  • Vaginal bleeding in early pregnancy
  • Very high levels of a pregnancy hormone called human chorionic gonadotropin (hCG)
  • Severe nausea and vomiting
  • Abnormal growth of the uterus (larger or smaller than expected)
  • Swelling in the feet, ankles, and legs.
  • High blood pressure
  • Heat intolerance
  • Restlessness
  • Weight loss

Molar pregnancies can be seen on ultrasound. The ultrasound shows a mass of tissue that looks like a bunch of grapes. In some types of molar pregnancy there may not be a fetus. In other types, there may be a fetus. However, the fetus will often be small and have abnormalities. Talk to your doctor if you are concerned about any of these symptoms. The type of doctor who manages pregnancy is called an obstetrician. To find an obstetrician near you, use the Find an OB-Gyn tool on the American College of Obstetricians and Gynecologists website.

Can hydatidiform moles cause any other health problems?

In most cases, hydatidiform moles are growths that are successfully treated. They are treated by removing the tissue mass (mole). Sometimes hydatidiform moles can grow deep into the uterine wall and develop into cancer. Sometimes a piece of the mole is left behind after removal. This piece can continue to grow and develop into cancer. The cancer may be low risk or slow growing. It can be treated with removal and chemotherapy (cancer drugs). In rare cases, a hydatidiform mole can grow into a fast-growing cancer type of cancer called choriocarcinoma. Choriocarcinoma may spread if not treated. It can also return after being treated. Talk to your doctor about the risks of cancer related to molar pregnancy. The type of doctor who manages pregnancy is called an obstetrician.
