Are There Higher Risks & Complications With A Twin Pregnancy?

Very simply put, there are more risks of complications with a twin or a multiple pregnancy. Having a twin or a multiple pregnancy is considered “high risk” because of the potential complications that can occur with a twin or multiple pregnancy. This does not mean that all or even most twin pregnancies will have complications, however.

One of the biggest risks with a twin pregnancy is the risk of premature labor and premature birth. Mothers who have a twin or multiple pregnancy are twice as likely to have preterm labor than mothers who have only one baby. Preterm labor is loosely understood as going into labor prior to the due date. Fortunately, if you are pregnant with twins, you can lessen your risk of having preterm labor by talking to your health care provider about how to avoid preterm labor and about how to watch for the signs of premature labor. The other good news is that, while premature birth still carries a great deal of risk for your babies, medical advances make it much more likely that preterm babies can survive and thrive.

Another serious risk for moms who are pregnant with multiples is the risk of high blood pressure, or pregnancy-induced hypertension. If this is very severe, it can even be preeclampsia. Preeclampsia is extremely serious, and typically is treated with bed rest. After delivery, the high blood pressure goes away, typically without any long-term effects.

There are other, less common risks and complications that can occur with a twin pregnancy. When multiples share a placenta, it can lead to Twin-To-Twin Transfusion Syndrome, in which there is an unequal flow of blood between the babies. A small number of twins are affected by Monoamniotic Monochorionic syndrome, or Mo-Mo Twins. This happens when the twins are enclosed in a single amniotic sac. In addition, moms of multiples or twins are more likely to experience gestational diabetes. There are also increased risks of heart problems for moms of twins.

If you are pregnant with twins and concerned about the risks and complications, your health care provider can help you to know what to watch for and to know what your treatment options are.
