VBAC: Is Vaginal Birth After Caesarean Right for You?

Many women who have had a previous caesarean section (C-section) wonder whether they can give birth vaginally in their next pregnancy. Vaginal birth after caesarean (VBAC) is a safe and viable option for many women but it’s essential to discuss your individual circumstances with your healthcare provider to determine if it’s right for you.

It’s essential to understand the factors that influence success rates, potential risks, and whether you’re a good candidate. Studies show that 60-80% of women who attempt delivery after caesarean, successfully deliver vaginally.

What Are the Benefits of VBAC?

• Faster Recovery – Avoids major abdominal surgery, leading to a quicker return to normal activities.
• Lower Risk of Complications – Reduces the likelihood of infection, excessive bleeding, and surgical complications.
• Better for Future Pregnancies – Having multiple C-sections increases the risk of placenta previa and placenta accreta in future pregnancies.
• Greater Birth Experience Satisfaction – Many women feel a sense of achievement with a vaginal birth.

Who Is a Good Candidate for VBAC?

Your doctor will assess several factors to determine whether VBAC is a safe option for you:

• Previous C-section type – The safest candidates had a low transverse uterine incision. Vertical or classical incisions have higher uterine rupture risks.
• Number of prior C-sections – Women with one previous C-section have the highest success rates. 
• Reason for previous C-section – If the C-section was due to fetal distress or breech position, vaginal birth may be more successful than if it was for slow labor progression.
• Overall pregnancy health – Conditions like high blood pressure, diabetes, or obesity may affect suitability.
• Hospital and medical support – VBAC should be attempted in a facility equipped for emergency C-sections if needed.

Did You Know? The chance of a successful vaginal delivery increases if labor starts spontaneously rather than being induced.

Success Rates & Factors That Influence Outcomes

Studies indicate that VBAC success rates range from 60% to 80%, depending on several factors:

While VBAC is often successful, about 20-40% of attempted VBACs result in an emergency C-section.

What Are the Risks of VBAC?

Although VBAC has many benefits, there are risks to consider:

• Uterine Rupture – A rare but serious complication where the previous C-section scar tears during labor (occurs in ~0.5% of those attempting VBAC).
  • In the event of a uterine rupture, there is an increased risk of requiring a hysterectomy or blood transfusion for the mother, and the baby faces a heightened risk of severe outcomes, including brain injury, permanent disability, or death.
• Emergency C-Section – If complications arise, an urgent Caesarean section may be required.
• Potential for Birth Injuries – In rare cases, prolonged labor could affect the baby’s oxygen supply.

A thorough risk assessment with your doctor will help determine if VBAC is the safest option for you.

How to Prepare for a VBAC

If you’re considering a vaginal birth after caesarean, preparation is key:

• Discuss with Your Doctor Early – Have a consultation to evaluate VBAC suitability.
• Stay Active & Healthy – Maintaining a healthy diet and regular exercise can improve labor outcomes.
• Choose a VBAC-Friendly Hospital – Ensure your birth facility is equipped for emergency care.
• Be Flexible – Have a birth plan but remain open to medical recommendations.
