There are no surefire means of miscarriage prevention, because in 75 percent of miscarriage, the cause is unknown. Oftentimes, the miscarriage or caused by a genetic or chromosomal abnormality that occurs by chance, and is not inherited from the parents. However, there are certain environmental, immunological and anatomical factors that have been linked with miscarriage, and these can be ameliorated to give parents a better chance to bring the fetus to term.
For starters, smoking is a cause of recurrent miscarriage—so if you smoke, a good prevention tip is simply to quit. Women should also avoid alcohol while pregnant. In 3 to 15 percent of women, an immune condition called antiphospholid syndrome can cause miscarriage as well; the good news is your doctor can diagnose this condition, and it is easily treated with low-dose aspiring and heparin, which increases blood flow to the placenta. About 1 percent of pregnancies are affected by a condition called cervical incompetence, which tends to cause rapid miscarriage between 16 and 18 weeks of gestation. Fortunately, this condition can be treated with a stitch to help hold the cervix closed. In addition, endocrine disorders such as uncontrolled diabetes and severe thyroid issues have also been linked to miscarriage; in this case, your doctor can prescribe a diet and medication regimen that will improve your chances of having a successful pregnancy.
