Miscarriage is an event that results in the loss of a fetus during early pregnancy. Also called spontaneous abortion (SAB), this typically occurs during the first half of pregnancy. According to the American Pregnancy Association (APA), 10 to 25 percent of all clinically recognized pregnancies end in miscarriage. (APA, 2011)
The cause of miscarriage varies from person to person, and in many cases, the cause is unknown. It is important for all pregnant women to know the facts about this condition so that they can better recognize the signs and risk factors associated with miscarriage.
Miscarriage is a broad term to explain the loss of a growing fetus. However, there are different types depending on the cause and stage of your pregnancy. Your doctor will classify your condition as a:
For a pregnancy to succeed, the mother’s body must supply the right amount of hormones and nutrients to the baby, and the fetus must develop correctly throughout the entire pregnancy. If either of these conditions is not met, then the pregnancy might end early.
There are a variety of causes of miscarriage. Common causes may include:
The symptoms of a miscarriage vary depending on the stage of pregnancy you’re in. For example, in a missed miscarriage, the event happens so suddenly that you may not have known you were pregnant in the first place.
Here are some of the warning signs of a miscarriage:
It is important to call your doctor right away if you experience any one or more of these symptoms.
Most miscarriages are due to natural, largely unpreventable causes. However, there are certain risk factors that can potentially increase your chances of an SAB. These include:
There is a misconception that a miscarriage will define your ability to get pregnant in the future. According to the Mayo Clinic, up to five percent of pregnant women have two consecutive SABs, while one percent experience three or more in a row. (Mayo Clinic, 2010)
Most women have successful pregnancies despite having an SAB. Miscarriage is a traumatic event, but this should not discourage women from conceiving again in the future.
It is important that you have a conception plan after an SAB and before you attempt another pregnancy. Being prepared for a future pregnancy by ensuring your body is in optimal health can decrease the likelihood that you will have another miscarriage. Your doctor will likely recommend tests to detect any problems that may have caused your previous miscarriage. These may include:
Depending on your overall health, your doctor might recommend that you wait several months before getting pregnant again. Periodic testing throughout your pregnancy may also be required.
If this is your first pregnancy, your general health should be a priority to help prevent miscarriage. Avoid alcohol, drugs, and smoking, and limit the amount of caffeine you drink. Prenatal vitamins can help support even the healthiest of diets to ensure that you and your baby get all of the nutrients needed. Light regular exercise can also improve fetal health, but don’t begin a new regimen without consulting with a doctor first.
Miscarriage is traumatic, and there are a wide range of emotions to deal with. Grief counselors can help you cope with any feelings you may have of guilt, loss, or depression. It is important to remember that most miscarriages are out of your control. Reach out to others for support. Depression is a potential and serious consequence of miscarriage that can worsen without treatment.
