Molar pregnancy is caused when the genetic components in the chromosomes develop some problems at the time of conception. It can lead to growth of eggs without embryo or with an uncharacteristic embryo.

Molar Pregnancy

Molar pregnancy is a condition in which fertilised egg grows into a mole rather than the normal embryo. At first, the symptoms of molar pregnancy are similar to those of normal pregnancy. Eventually, you start to get symptoms that indicate something is wrong. It is an unwholesome way of losing pregnancy but with timely treatment, you can ensure that it does not have long-lasting consequences.


The symptoms of molar pregnancy other than the usual pregnancy symptoms of morning sickness and missed period are –

  • Excessive vaginal bleeding.
  • Unusually large uterus.
  • Severe case of nausea with vomiting.
  • Symptoms of hyperthyroidism. They are nervousness, tiredness, faster than usual or irregular heartbeat.
  • Uncomfortable sensations in the pelvis.
  • Early preeclampsia.
  • Rare disorders such as thyroid disease are developed.
  • Increased levels of hCG.
  • Grapes-shaped tissues discharged from the vagina. This more or less confirms that it is molar pregnancy.


Causes of a Molar Pregnancy

Molar pregnancies do not occur very often. According to American Pregnancy Association, molar pregnancy occurs in 1 out of every 1,000 pregnancies. They are also known as gestational trophoblastic disease (GTD), hydatidiform mole but mostly called by the simple one word “mole.”

What Needs to be done?

Even though molar pregnancy is nothing when compared to abortions and miscarriages, i.e. end of a child developing inside you, it is still a loss. The embryo was developed but it did not transform into a child, a life. What makes the experience traumatic is the fact that women usually learn about molar pregnancy when they have started preparing for their child. All their hopes of becoming a mother are dashed. That is why it is important that you understand the symptoms of molar pregnancy lest it leads to the same situation for you too.


Many of the symptoms mentioned above are also possible with normal pregnancy or if it is the case of multiple pregnancy. They can also be found due to miscarriage. Doctors diagnose molar pregnancy with a pelvic exam, blood test for measuring pregnancy hormones and a pelvic ultrasound.


The fact that molar pregnancy initally has normal symptoms of pregnancy, should trigger you to first check out your pregnancy symptoms. You don’t want to be unwise in this situation.
