There’s plenty of research to suggest that a vaginal birth after C-section (VBAC) is a safe option for many women who have had one previous C-section and who have been identified as low risk. In fact, recent statistics shows just how old-fashioned the “once a c-section always a c-section” school of thought really is.
Some positive stats to consider
According to the American Pregnancy Association, published studies show that 60% to 80% of women who had a cesarean birth have had a successful vaginal birth in their next pregnancy. This statistic is supported by another from the National Institute of Child Health and Human Development that showed that about 75% of VBAC attempts are successful.
Still, your choice to pursue VBAC or schedule a repeat C-section can be difficult. Here’s a bit of insight that will help you make the right decision.
Why consider VBAC?
Compared with having another C-section, a successful vaginal delivery can help avoid bowel or bladder issues, hysterectomy or even issues with the placenta in other pregnancies. The more immediate benefits are a shorter hospital stay and recovery, lower infection risk, less risk of blood loss and a quicker return to normal activities.
What are the risks of VBAC?
One of the main risks associated with VBAC is a uterine rupture. A uterine rupture occurs when the wall of the uterus breaks open, often because of pressure caused by pregnancy or contractions. While a uterine rupture can be a life-threatening complication for both the mother and the baby, it is very rare.
There is a lower chance of success for VBAC if:
- You have high blood pressure, diabetes, or obesity
- You are older than 35
- You’re more than 40 weeks pregnant
Am I a candidate for a VBAC?
Generally speaking, you’re a good candidate if you’ve had a prior vaginal delivery. Other factors in your medical history that increase the odds of a successful VBAC include:
- You’ve had just one c-section in the past with a low transverse (horizontal) incision on the uterus
- You and your baby are in good health during pregnancy
- You are younger than 35
- Your labor starts on its own just before or on your due date
The reason you needed a C-section in your previous pregnancy is the strongest predictor of whether you will have a successful VBAC. If you had complications, you would be less likely to have a successful VBAC.

Talk to your doctor
Your decision about whether to attempt a VBAC must be made carefully. Your medical history, current health status and plans for the future all need to factor into the decision on how to handle the delivery of your baby. If you are pregnant and have had a Cesarean delivery in the past, talk to your OB-GYN about a potential VBAC. Your doctor will review all the details of your C-section and help determine if you’re a good candidate.
