VBAC: Can You Have a Vaginal Birth After a Previous Caesarean?

India's caesarean section rate has risen dramatically over the past two decades — currently around 21% nationally, significantly higher in private urban hospitals. This means an increasing number of women entering their second or subsequent pregnancy have a uterine scar from a previous caesarean and are asking: do I have to have another c-section, or can I try for a vaginal birth?
The short answer is that many women with one previous caesarean are good candidates for a trial of vaginal birth — called VBAC (vaginal birth after caesarean). VBAC is not a reckless choice or a compromise. It is a medically established option with documented benefits, specific candidacy criteria, and known risks that are manageable in the right setting.
Dr. Shachi Singh, consultant obstetrician at Prakash Hospital, Sector 33, Noida, explains who is a VBAC candidate, what the risks are, and how to have an informed conversation with your obstetrician.
What VBAC Is
VBAC is a vaginal delivery in a woman who has had at least one previous caesarean section. The term TOLAC (trial of labour after caesarean) is also used — emphasising that it is a planned attempt at vaginal birth with the understanding that caesarean may still be needed if labour does not progress safely.
In well-selected women, the VBAC success rate is approximately 60 to 80%. This means 6 to 8 out of every 10 women who attempt TOLAC will achieve vaginal delivery.
Why Consider VBAC?
Benefits of successful VBAC compared to repeat elective caesarean:
- Faster recovery — vaginal birth recovery is typically 2 to 4 weeks versus 6 to 8 weeks for caesarean
- No surgical wound — no abdominal scar, no wound healing complications
- Earlier return to normal activities and caring for the new baby and older children
- Lower maternal blood loss compared to repeat caesarean
- Reduced risk of placenta praevia and placenta accreta in future pregnancies — each caesarean increases the risk of abnormal placentation in subsequent pregnancies, which is one of obstetrics' most dangerous complications. Achieving a vaginal birth breaks this accumulating scar burden.
Benefits of planned repeat caesarean compared to TOLAC:
- Completely eliminates the risk of uterine rupture (though this risk in TOLAC is small)
- Predictable timing and circumstances
- No risk of emergency caesarean during labour
The decision is not one-size-fits-all. It involves weighing individual clinical factors, the woman's preferences, and the setting's ability to provide safe monitoring.
The Main Risk: Uterine Rupture
The primary concern with TOLAC is uterine rupture — the opening of the previous caesarean scar during labour. When this occurs, it is a serious emergency: it can cause rapid fetal compromise and significant maternal haemorrhage.
The rate of uterine rupture during TOLAC in women with a single previous low transverse caesarean scar is approximately 0.5 to 1% (1 in 100 to 1 in 200). This is a real risk — it is not negligible — but it is also a small absolute risk in well-selected women at an appropriately equipped facility.
Warning signs of uterine rupture during labour:
- Sudden severe abdominal pain, particularly between contractions
- Loss of fetal heart rate — sudden fetal bradycardia on CTG
- The woman's contractions suddenly stopping after strong labour
- Signs of maternal shock (rapid heart rate, falling blood pressure)
These are recognised on continuous CTG monitoring and responded to with emergency caesarean.
Who Is a Good VBAC Candidate?
Favourable factors for VBAC:
- One previous caesarean with a low transverse uterine incision (horizontal cut in the lower part of the uterus) — the standard scar in modern obstetrics
- Reason for previous caesarean was not recurrent — if the previous c-section was for a non-recurrent reason (e.g., breech presentation, placenta previa, fetal distress in that specific pregnancy), the likelihood of vaginal birth this time is higher
- No previous uterine rupture or classical (vertical) uterine incision
- Normal anatomy of the pelvis — no known pelvic abnormality preventing vaginal birth
- Baby not macrosomic (very large)
- Spontaneous onset of labour — induction of labour for VBAC carries higher risk than spontaneous labour, though it is not absolutely contraindicated in all settings
Factors that make VBAC less appropriate or contraindicated:
- Two or more previous caesarean scars
- Classical (vertical) uterine incision from a previous surgery
- Previous uterine rupture
- Placenta previa in current pregnancy
- Fetal malpresentation (e.g., transverse lie)
- Medical or obstetric complications that would themselves indicate caesarean
- Facility without capacity for immediate emergency caesarean and blood transfusion — VBAC should only be attempted where continuous fetal monitoring and rapid surgical capability are available
VBAC in India: The Practical Reality
In India, VBAC is less commonly offered than in many other countries — for reasons that include medico-legal concerns, institutional policies, limited availability of continuous intrapartum monitoring, and the preference of both doctors and patients for the predictability of planned caesarean.
This means that women who want to attempt VBAC need to:
- Raise it early — ideally at the booking appointment, well before the third trimester
- Have a detailed discussion with their obstetrician about their specific candidacy
- Ensure the facility where they plan to deliver has continuous CTG monitoring capability and immediate operative capability if needed
- Have a realistic understanding of the risks and the possibility that labour may still end in caesarean
A woman who is told "once a caesarean, always a caesarean" without a proper individual assessment of her candidacy deserves to have her situation reviewed — this blanket policy is not evidence-based.
What VBAC Labour Looks Like
Admission: Typically earlier than for a woman without a uterine scar, to ensure monitoring is in place from the onset of active labour.
Continuous CTG: Unlike low-risk labours where intermittent monitoring is acceptable, VBAC requires continuous electronic fetal monitoring throughout active labour. This detects the earliest signs of fetal compromise from uterine scar stress.
IV access: An intravenous cannula is placed on admission — to allow rapid IV access if emergency caesarean is needed.
Epidural: Not contraindicated for VBAC. The concern that epidural masks pain from uterine rupture is not well-supported — the CTG remains the primary monitoring tool, not the woman's pain level.
Labour progress: The same expectations apply as for any labour. Progress is assessed. If labour is not progressing, the decision about whether to continue or move to caesarean is made clinically.
Postpartum: After successful VBAC, the obstetrician typically examines the uterine scar manually to confirm it is intact.

Frequently Asked Questions
1. Is VBAC safe?
For well-selected candidates at an appropriately equipped facility, VBAC is a medically established and safe option. The main risk — uterine rupture — occurs in approximately 0.5 to 1% of TOLAC attempts and is managed with continuous monitoring and rapid surgical response.
2. What is the success rate of VBAC?
In well-selected women, 60 to 80% of TOLAC attempts result in successful vaginal delivery.
3. Can I have VBAC if I had two previous caesareans?
Generally, two or more previous caesareans significantly increase the risk of uterine rupture and VBAC is not typically recommended. Individual assessment by an experienced obstetrician is appropriate.
4. Will my obstetrician support VBAC?
This varies. Raise the question early and request an individual assessment of your candidacy — not a blanket policy response. If you are told VBAC is not possible without a proper clinical review of your specific history, seek a second opinion.
