A molar pregnancy occurs when the fertilisation of the egg by the sperm goes wrong and leads to the growth of abnormal cells or clusters of water filled sacs inside the womb. This condition is one of a group of conditions known as gestational trophoblastic tumours (GTTs). Molar pregnancies used to be called hydatidiform mole but now most people call them molar pregnancies. Most molar pregnancies are benign (not cancerous). They can spread beyond the womb in some women, but are still curable.
Complete molar pregnancy – when the egg with no genetic information is fertilized by a sperm or when the nucleus of an egg is either lost or inactivated. The sperm grows on its own, duplicates itself because the egg was lacking genetic information but it can only become a lump of tissue. It cannot become a fetus. Usually there is no fetus, no placenta, no fluid and no amniotic membranes. As this tissue grows, it looks a bit like a cluster of grapes. This cluster of tissue is called a mole and it can fulfill the uterus. The uterus is rather filled with the mole that resembles a bunch of grapes.
As so little is understood about how and why hydatidiform moles occur, they're difficult to prevent. However, good healthy nutrition may decrease the risk of one developing and any other common pregnancy complications. Each individual’s case is different but the vast majority of patients begin on Methotrexate. This is also used for arthritis and skin conditions. It is administered by intra-muscular injections followed by a Folinic Acid (NOT folic acid) tablet exactly 24 hours later.
