Miscarriage: Understanding Common Causes


Miscarriage: Understanding Common Causes

Suffering a miscarriage is one of the most painful experiences an expectant couple can go through. One moment you are eagerly awaiting the arrival of your bundle of joy; the next, all that joy has been taken from you. You’re not alone. Of recognized pregnancies, 10-15% of women are at risk of miscarriage. Of those, approximately 80% of miscarriages happen in the first trimester. Understanding the most common causes of miscarriages may help.

Chromosomal Abnormalities

Most miscarriages occur within the first trimester of pregnancy and are due to chromosomal abnormalities with the fetus. This can happen regardless of the health of the parents. Fortunately, these types of miscarriages, while emotionally difficult to deal with, are not indicative of future fertility issues. Parents can continue to conceive and carry other pregnancies to term.

Lifestyle and Environmental Hazards

Most people know that women who engage in drug or alcohol abuse during pregnancy are more likely to suffer a miscarriage. But even women who actively strive for a healthy pregnancy may fall victims to environmental hazards they may not be aware of. Older homes that contain lead, mercury, or arsenic can contribute to miscarriages. It’s a good idea to have your home tested if it was built before 1978. Women working around hazardous chemicals should use extra caution during pregnancy.

Medical Conditions

Miscarriages that happen in the second or third trimester are often due to medical conditions with either the mother or the fetus. Autoimmune disorders such as lupus or conditions like diabetes, thyroid disorders, and high blood pressure can cause miscarriages if left untreated. Women who suffer from multiple or recurrent miscarriages should seek out medical advice from a fertility specialist to pinpoint the exact causes of miscarriages.
