Miscarriage is also known as pregnancy loss or spontaneous abortion. It refers to the natural demise of the fetus or embryo before it is able to survive independently. Some professionals use the cut-off point of 20 weeks gestation where it is later known as a stillbirth. Miscarriage is hard for mothers as it is often later associated with anxiety, sadness, and guilt.

As many as 80 percent of miscarriages occur during the first trimester. The prevention of a miscarriage may be possible with good prenatal care. This includes avoiding infectious diseases, radiation, drugs, alcohol, and more.

Although most miscarriages are often complete without the need for additional interventions, medication such as misoprostol or a vacuum aspiration procedure is sometimes necessary to remove the remaining tissue. The rate of miscarriage is estimated around 10 to 20 percent. This number increases to 45 percent for those above the age of 40.

Cause #1: Genetics and Age

Approximately 50 percent of early pregnancy loss is due to the abnormal number of chromosomes. Chromosomes refer to structures in the cells that carry genes. The sperm and egg both have 23 chromosomes.

This means when fertilization occurs and both the sperm and egg joins, the two sets of chromosomes also join becoming a total of 46 chromosomes. When the sperm or egg has a different number of chromosomes, it would affect the total chromosomes the embryo has resulting in developmental abnormality which may lead to pregnancy loss or miscarriage.
