Molar Pregnancy

A molar pregnancy is a mass of abnormal tissue that comes from the placenta inside the uterus; this causes problems with the pregnancy. Only about 1 in a 1000 women ever experience a molar pregnancy. There are two types of molar pregnancies:

• Complete molar pregnancy - instead of a normal placenta and embryo, the abnormal tissue grows in the uterus in a grapelike cluster which can actually fill the uterus.

• Partial molar pregnancy - the placenta grows abnormally. Any fetal tissue that does develop is more likely to have severe defects.

Risks Involved in a Molar Pregnancy

• Excessive bleeding

• Torphoblastic disease

• Invasive cancer

• The abnormal tissue can spread to other parts of the body and metastasize - which basically means that if the tissue becomes cancerous it can spread to other parts of the body

Symptoms of Molar Pregnancy

A molar pregnancy replicates the same symptoms that a normal pregnancy does, a missed period, tender breasts, fatigue, increased urination, and even morning sickness. But it can also cause other symptoms like:

• Vaginal discharge of grapelike tissue

• Vaginal bleeding

• A uterus that is abnormally large for the gestation of the pregnancy

• Severe nausea and vomiting

• Signs of hyperthyroidism - fatigue, weight loss, increased heart rate, heat intolerance, sweating, irritability, anxiety, muscle weakness, and thyroid enlargement


If you think that you have a molar pregnancy, you doctor can do a pelvic exam, a blood test of your pregnancy hormone levels, and a pelvic ultrasound that will confirm whether or not you have a molar pregnancy.


If it is confirmed that you have molar pregnancy, you will need immediate treatment to remove all of the abnormal tissue from your uterus. After your uterus has been cleared of this tissue, you will have periodic pregnancy hormone levels done to test for signs of persistent cell growth in your uterus. These tests will be done routinely for 6 to 12 months.
