Obesity is defined. Obesity is defined as a BMI greater than 30 and we all know that obesity is a serious health problem. But obesity in pregnancy can also increase your risk of pregnancy-related complications including birth defects and miscarriage. Studies have shown that miscarriage is more common in obese women than in age-matched women with a normal range BMI.

Blood clotting disorders: Some blood clotting disorders, such as systemic lupus erythematosus and antiphospholipid syndrome can cause ‘sticky blood’ and recurrent miscarriage. These rare disorders of the immune system affect the flow of blood to the placenta and may cause clots that prevent the placenta from functioning properly, depriving the baby of vital oxygen and nutrients, that may result in. Causes Most miscarriages are due to things that are out of your control. More than half happen because of problems with chromosomes, which.

Infections. Uterus or cervix infections can be dangerous to a developing baby and lead to miscarriage. Other infections that may pass to the baby or placenta can. About half of all miscarriages that occur in the first trimester are caused by chromosomal abnormalities — which might be hereditary or spontaneous — in the father’s sperm or the mother’s egg.

Chromosomes are tiny structures inside the cells of the body that carry many genes, the basic units of heredity. In fact, about 50 percent of all early pregnancy losses are due to chromosomal abnormalities. 2  However, some lifestyle choices can increase your risk of miscarriage, such as cigarette smoking and drug use.

Other less common causes of miscarriage include: 1  structural problems of the uterus or cervix.

List of related literature:

The causes of miscarriage are not entirely clear, but some may be due—at least in part—to a poor match of the genetic components (sperm and egg) at the time of conception, to the pregnant teen’s heavy use of harmful substances (alcohol, tobacco, drugs), or to serious infections during pregnancy.
