Vaginal Birth After C-Section (VBAC): Is It Right for You?

If you've previously had a cesarean section (C-section) and are pregnant again, you may be wondering if a vaginal birth after C-section (VBAC) is an option for you. While VBAC is possible for many women, there are several factors to consider when deciding if it's the right choice for you and your baby.

Factors to Consider When Choosing VBAC

The most important thing to keep in mind when considering VBAC is the safety of both you and your baby. Your doctor will help you assess the following factors to determine if VBAC is a safe option:

Your Health

For VBAC to be considered, both you and your baby must be in good health. In some cases, even women pregnant with twins may be able to attempt VBAC if their doctor determines that everyone is healthy enough. However, certain health conditions may make VBAC too risky, including:

  • Obesity (body mass index of 30 or higher)

  • Pre-eclampsia (high blood pressure during pregnancy)

  • Advanced maternal age (usually older than 35)

  • A previous cesarean within the last 19 months

  • A very large fetus

Your Previous C-Section Scar

The type of scar you have on your uterus from your previous C-section is a crucial factor in determining if VBAC is safe for you. There are two types of incisions made during a C-section:

  • Vertical incision (top to bottom)

  • Transverse incision (side to side)

If you have a vertical C-section scar, VBAC is not an option due to the high risk of uterine rupture during labor. However, if you have a low transverse scar and other risk factors are low, your doctor may allow you to attempt VBAC.

Hospital Preparedness

Not all hospitals are equipped to handle VBAC attempts. Even though the risk of uterine rupture is low, the hospital must be prepared to handle this emergency situation should it arise. Check with your doctor early on to ensure that the hospital you plan to use allows VBAC.

Benefits of Successful VBAC

If VBAC is an option for you and you're interested in attempting a vaginal birth, there are several potential benefits to consider. Approximately 70% of women who attempt VBAC are successful. Compared to a repeat C-section, a successful VBAC offers:

  • No need for surgery

  • Less blood loss

  • Faster recovery

  • Reduced chance of infection

  • Lower risk of injury to the bladder or bowel

  • Fewer complications with future childbirths

It's important to note that even with a low transverse scar and good health, there is still a small chance (less than 1%) of uterine rupture during VBAC. While rare, this complication can be very dangerous for both mother and baby. Be sure to discuss the risks and benefits thoroughly with your doctor before making a decision.
