Overview

You might be able to have a VBAC (vaginal birth after cesarean), but whether it’s a safe and realistic option depends on several personal and medical factors. Many people who have had a previous cesarean section (C-section) are candidates for VBAC, and about 60–80% of those who attempt it are successful. The decision is best made in partnership with your OB/GYN, who can review your specific health history and the details of your prior C-section(s).

Key Points About VBAC

What is VBAC?

• VBAC stands for vaginal birth after cesarean. It involves attempting a vaginal delivery after having had a previous C-section.
• The process of attempting a VBAC is called a trial of labor after cesarean (TOLAC).

Who is a Candidate for VBAC?

• Most people with one previous low-transverse (side-to-side) uterine incision are considered candidates.
• You are less likely to be a candidate if you have had a classical (vertical) uterine incision, more than one prior C-section, or a history of uterine rupture or other uterine surgery.
• Other factors that can affect candidacy include the reason for your previous C-section, your overall health, the presence of certain pregnancy complications, and the resources available at your hospital.

Factors That Affect VBAC Success

• Higher chance of success if your previous C-section was for a non-recurrent reason (like breech baby or fetal distress, not labor that didn’t progress).
• Prior vaginal delivery (before or after your C-section) increases the likelihood of a successful VBAC.
• Spontaneous (natural) onset of labor is associated with higher success rates than induced labor.
• Factors that may decrease success rates include maternal age over 35, obesity, diabetes, pregnancy past 40 weeks, and a large baby (over 4 kg).

Risks of VBAC

• The main risk is uterine rupture, where the scar from the previous C-section tears during labor. This is rare (less than 1% of cases), but it is a serious complication that can be dangerous for both you and your baby.
• Other risks include infection, bleeding, and the possibility of needing an emergency C-section if labor does not progress or if complications arise.

• Not all hospitals or providers offer VBAC, so it’s important to discuss this early in your pregnancy.

Summary

VBAC is a safe and reasonable option for many people who have had a previous C-section, with a 60–80% success rate. Your individual chances depend on your medical history, the reason for your prior C-section, and other health and pregnancy factors. The main risk is uterine rupture, which is rare but serious. It’s recommended to discuss your specific situation with your OB/GYN, who can work with you on your personal course of care and help you weigh the risks and benefits.

Overview

A good candidate for a VBAC (vaginal birth after cesarean) is someone whose medical and pregnancy history suggests a high likelihood of a safe and successful vaginal delivery after a previous C-section. Several factors can increase or decrease your chances of success.

Key Factors That Make Someone a Good Candidate for VBAC

Type of Uterine Incision

• Low-transverse (horizontal) incision: This is the most common and safest type for VBAC, with the lowest risk of uterine rupture.
• Other incisions (classical/vertical or T-shaped): These are usually considered higher risk and are generally not recommended for VBAC.

Reason for Previous C-Section

• Non-recurrent reasons: If your previous C-section was for reasons unlikely to happen again (such as breech baby or fetal distress), your chances of a successful VBAC are higher.
• Recurrent reasons: If your C-section was for reasons like labor not progressing (cephalopelvic disproportion), your chance of VBAC success may be lower, but it is not an absolute barrier.

Summary

You are more likely to be a good candidate for VBAC if you have a low-transverse uterine scar, had a previous C-section for a non-recurrent reason, have had a prior vaginal delivery, are younger than 35, have a healthy weight, and go into labor spontaneously. Your OB/GYN can help you review your specific history and current pregnancy to assess your chances and discuss the safest options for you.
