Common causes of miscarriage

Common causes of miscarriage

Well over 20% of pregnancies end in miscarriage, below are the most common reasons why:

  • Blighted ovum:

    The single most common cause of miscarriage is responsible for about half of all first-trimester losses. Basically, conception and implantation occurs, but the embryo (your baby) fails to develop for various complex bio-genetic reasons.

  • Genetic failures:

    Miscarriages with fetal or embryonic death -- also known as “Intrauterine fetal demise” by the medical community, refers to the untimely death of the fetus/embryo due to chromosomal and/or other genetic abnormalities not understood at the time of death.

  • Molar pregnancy:

    Molar pregnancies are rare and occur as a result of an abnormal implantation process which - rather than developing a normal placenta to filter blood between you and your child, masses of rapidly growing cystic tissue develop instead. If an embryo is present it will not survive. Often - due to the abnormal cellular growth, no embryo develops at all.

    A molar pregnancy requires a surgical procedure known as suction dilation and curettage (D&C) in order to remove the placental mass and prevent further cystic tissue or tumors from developing.

  • Ectopic pregnancy:

    In rare instances the fertilized egg will fail to descend into the uterus and instead implants in your fallopian tube’s wall. Because your fallopian tubes are much too small (and not intended) to house a growing human, the pregnancy must be terminated or risk both the life of the mother and child.
