Why Do I Keep Having Miscarriages?

Why Do I Keep Having Miscarriages?

A miscarriage is devastating. It’s normal to wonder why you lost your baby and if, somehow, you could have done something differently to avoid it. When it happens a second time, or a third, you may be in such a state of grief that you don’t want to share your pain with anyone. 

Recurrent miscarriage is rare, affecting only 1% of women. But when it happens to you, you deserve to know why. 

At Noble Fertility Center in New York City’s Murray Hill neighborhood, fertility expert Peter L. Chang, MD, also specializes in determining the reasons for, and reducing the odds of, recurrent miscarriage. He and our entire team understand how emotionally and physically draining a miscarriage is, and we want to help you build the family of your dreams. 

If you’ve miscarried two or more times, Dr. Chang conducts an in-depth evaluation and diagnosis to determine all of the factors at play so you can minimize your risks for another miscarriage. Following is a guide to some of the most common reasons for multiple miscarriages and how you can overcome them and go on to have a healthy pregnancy.

Chromosomal abnormalities

The most common reason for miscarriage is chromosomal abnormalities in the fetus. In fact, problems with chromosomes account for up to 60% of miscarriages

You have no control over whether your embryo receives the normal amount of chromosomes during fertilization. However, your fetus is more at risk for chromosomal abnormalities if the female partner is older or if you or your partner have a condition called chromosome translocation. 

We use a simple blood test to determine the presence of chromosomal translocation, which is an unusual arrangement of your chromosomes. We may recommend in vitro fertilization (IVF) so you can test embryos for abnormalities before implantation. Ask us about our preimplantation genetic screening and diagnosis (PGS/PGD) services.

Women who are at risk for chromosomal abnormalities due to advancing age may also consider IVF. By choosing embryos with a normal chromosomal arrangement, you reduce your risk of miscarriage.

Medical problems

During a recurrent miscarriage workup, Dr. Chang also determines if you have underlying medical conditions that raise your risk for miscarriage. Some of the most common are:

Antiphospholipid syndrome (APS)

Antiphospholipid syndrome (APS) is an autoimmune disorder that causes your body to attack its own healthy cells. If you have APS, you’re more likely to develop blood clots and complications during your pregnancy that could lead to miscarriage.

APS is highly treatable. More than 80% of women who are treated for APS have healthy live births, and 60% have no complications during their pregnancy.

Thrombophilia

Thrombophilia is a condition that makes your blood clot abnormally, which raises your risk for recurrent miscarriage. APS is, in fact, a form of thrombophilia. Treatment for thrombophilia with aspirin and heparin drastically reduces your risk of miscarriage.

Polycystic ovary syndrome (PCOS)

Polycystic ovary syndrome (PCOS) is an imbalance in your hormones that raises your risk for miscarriage. If you have PCOS and want to become pregnant, we work with you to reduce risk factors — which include being overweight or having diabetes — and we may recommend medications such as metformin to control your blood glucose levels.

Structural problems

If you have structural abnormalities in your uterus or cervix, you may not be able to carry a baby to term. Surgery isn’t always advisable because it could cause other issues that affect your fertility. However, if you have a weak cervix, we may recommend a procedure that closes the cervix until you’re ready to deliver. 

Depending on your individual situation, Dr. Chang may also recommend lifestyle changes, including weight loss before your pregnancy and bedrest during pregnancy. If you have severe structural abnormalities, he may recommend a gestational surrogate to carry your baby to term.
