Causes of Miscarriage – Understanding what causes Pregnancy Loss

According to a research, it has been proved that most of the early miscarriages (about 60 per cent of those that occur in the first trimester) remain mysterious. It is generally believed these losses are inherent, wherein the chromosomes just fail to reproduce accurately. Most people also think that a health condition that had occurred in the recent times, such as an illness, an accidental fall, or exposure to a certain thing will have caused the miscarriage. However, this is not true. This is because by the time a miscarriage is detected or set in motion, the baby has been lost for quite some time!

Stated below are some of the most common causes of a miscarriage:


With hormone problem being the reason, a woman is more likely to suffer from a miscarriage within 10 weeks. Problems like low progesterone, luteal phase defect, and effects of untreated thyroid disorder can result in a miscarriage.

Chromosome Defects

There are a number of factors that play significant role during the union of egg and sperm to create the first cell. The successful union with perfect chromosomes can still result in problems. Certain chromosome defects may be responsible for the death of a newly fertilized egg. This can account for up to 60 per cent of early miscarriages.

Troubles with the Uterus or Cervix

Some women gave uterus with unusual shape. Others have a cervix weakened by certain medical causes. This results in miscarriage.

Immune Disorders

Antiphospholipid antibodies can result in blood clots inside the placenta that block or retard blood supply to the baby. This results in slow growth or death of the baby. This has become one of the rarest causes of a miscarriage because of technological advancement in the field of medicine.

Early Labor or Premature Rupture of Membranes

Most miscarriages start with cramping and symptoms similar to labor. Sometimes the water breaks before 37 weeks. This is a difficult situation for mother and the child.

Others Causes of Miscarriage

Infections such as malaria, syphilis, mycoplasma, and toxoplasmosis can cause miscarriage. Infections directly affecting the uterus are at huge risk. Common illnesses can result in miscarriage or fetal malformation in the event where you get them for the first time during pregnancy such as Chicken Pox. Age may be another factor in miscarriage. The aged egg or sperm and hormonal imbalance can make it really difficult for pregnancy to continue. However, these problems are rare until you reach 40. Health conditions such as diabetes, heart problems, and thyroid disorders can complicate the pregnancy.

Accidents do NOT cause Miscarriage

Since the baby is protected in its amniotic sac, surrounded by fluid, even a very hard blow to the abdomen will just rock it.
