Reasons for Early Miscarriage Abortion

A pregnancy that is lost before 20 weeks is termed as an early miscarriage. Due to some accident or as a natural reaction of the woman’s body to external or internal factors that affect pregnancy, the baby may be forced out of the uterus. Another term used to describe a miscarriage is spontaneous abortion.  Those miscarriages occurring in the second trimester are called late miscarriages.

Spontaneous miscarriages are quite frequent, usually happening before the pregnancy is three months long. It is estimated that one in every four women will have a miscarriage in the span of childbearing years. 
Being aware of early miscarriage symptoms can help a woman reach medical care promptly. They are
Cramped feeling in the abdomen
Bleeding in the vagina/Hemorrhaging coupled with blood clotting
Insistent pain in the lower back region
A woman is at a greater risk for an early miscarriage if she has
Deficiency of progesterone
Thyroid problem
Auto immune disease
One or all of the these habits – smoking, drinking, substance abuse
Older women are more at risk for early miscarriages. It is a fact that every one out of the two women who conceives when she is 40 years or older has an early miscarriage. Sometimes a miscarriage may also occur due to environmental factors (occupational hazards like exposure to toxins).  
Reasons for early miscarriage
Blighted ovum (when the ultra-sound scan shows a pregnancy sac with no embryo) is a common reason for early miscarriage. At times, in the absence of a scan the abnormality may remain undetected for an indeterminate period
When the fertilized egg develops outside the uterus this is called ectopic pregnancy. The egg may be situated in the abdomen, fallopian tubes or in the ovaries. This kind of pregnancy is generally accompanied by pain in the abdomen and likely to be terminated by an early miscarriage
Genetic abnormality of either or both parents passed on to the fetus
Infected genital tract of the pregnant woman
Hormonal abnormality of the woman
Abnormality or malformation in the structure of the uterus or cervix
Abnormality in number or structure of the chromosomes of the fetus is the most widespread reason for an early miscarriage; in fact 70 out of 100 miscarriages that happen in the first trimester is because of an abnormality in the chromosomes
Parasitic infections like toxoplasmosis
Viral infections like cytomegalovirus
Bacterial infections like mycoplasma or streptococcus
Stress and pressure suffered by the woman for various reasons
 Contrary to popular belief miscarriages rarely occur because of a fall.   In most cases, miscarriages are due to circumstances beyond control of the affected women. Miscarriages are also not caused because of exercise or sexual intercourse during the period of pregnancy.
 Early miscarriages are unfortunate and happen usually within the first 20 weeks of pregnancy. The various reasons include chromosomal abnormality, defective structure of the uterus or cervix of the woman, certain bacterial, viral or parasitic infections, blighted ovum and ectopic pregnancy. Women who are habitual smokers, or who indulge in substance or alcohol abuse are more at risk for an early miscarriage. Women with diabetes or hormonal abnormality are also at risk for early miscarriage. Exercise, sexual activity or regular work does not induce an early miscarriage.
