VBAC in Singapore: A Practical Guide for Mums Planning a Vaginal Birth After Caesarean

VBAC stands for vaginal birth after caesarean, and yes, it is possible in Singapore. If you had a caesarean for your first baby, you are not automatically committed to a repeat surgery for the next one. Many women who had one low-segment (the usual horizontal cut near the bikini line) caesarean go on to deliver vaginally, with a typical success rate of around 60 to 70 percent. Whether VBAC is right for you depends on the reason for your first caesarean, the type of scar you have, your current pregnancy, and the hospital and obstetrician you choose. This guide walks through how VBAC works locally, who is a suitable candidate, the risks involved, and how to plan for it with your care team.

Singapore has strong maternity care across both public and private hospitals, and most major centres support women who want to attempt a VBAC where it is medically safe. The medical term for this attempt is a trial of labour after caesarean, sometimes shortened to TOLAC. If the trial of labour succeeds, you have a VBAC. If complications arise during labour, your team may recommend an unplanned caesarean. Going in with realistic expectations and a clear plan makes the whole experience far less stressful.

What VBAC actually means

A caesarean involves cutting through the wall of the uterus to deliver the baby, and that cut heals into a scar. The concern with any future labour is whether that scar will hold up to the contractions of a vaginal birth. For the vast majority of women whose previous caesarean was done through a low transverse incision, the scar is strong and labour can proceed safely under monitoring. This is why the type of scar you have, not just the fact that you had a caesarean, drives the decision.

It helps to separate two ideas. The first is your eligibility, meaning whether the clinical facts of your history make a trial of labour reasonable. The second is your success rate, meaning how likely that trial is to end in a vaginal birth rather than another caesarean. You can be perfectly eligible and still end up with a repeat caesarean if labour does not progress, and that is a normal outcome, not a failure. Talking through both ideas with your gynae early matters, which is part of why choosing the right doctor is so important. If you have not settled on one yet, our guide on how to choose a gynae in Singapore covers what to ask before you commit.

Who is a good candidate for VBAC

VBAC tends to be offered when your history and current pregnancy are straightforward. The single biggest factor that raises your chance of success is a previous vaginal birth. Women who had one caesarean but also delivered vaginally at some point have success rates of roughly 80 to 90 percent, noticeably higher than the 60 to 70 percent seen with one caesarean and no prior vaginal delivery.

You are more likely to be considered a good candidate if the following describe you:

• You have had only one previous caesarean, done through a low transverse (horizontal) incision
• The reason for your first caesarean was a one-off, such as the baby being in distress or in an awkward position, rather than something likely to repeat
• You are carrying a single baby who is head-down
• Your pregnancy has been low-risk with no placenta problems
• You go into labour naturally or close to your due date
• You are delivering in a hospital equipped for emergency caesarean if needed

VBAC is generally not recommended, and a planned repeat caesarean is safer, when any of these apply:

• Your previous incision was classical (a vertical cut high on the uterus) or another high-risk scar type
• You have had two or more previous caesareans
• The placenta is lying low and covering the cervix (placenta praevia)
• Your baby is breech or lying sideways
• There is another reason a vaginal birth would be unsafe in this pregnancy

VBAC versus a planned repeat caesarean

There is no universally right choice between attempting a VBAC and booking a planned repeat caesarean. Each path carries its own benefits and trade-offs, and the best decision depends on your priorities, your medical history and how this pregnancy is going. The table below lays out the main differences to help you weigh them up with your care team.

One number worth keeping in perspective is the scar rupture risk. After a single low transverse caesarean, the chance of the scar giving way during labour is under 1 percent. It is a serious event when it happens, which is why VBAC is done in hospitals with continuous monitoring and the ability to move to emergency surgery quickly, but it is also uncommon. For most eligible women, the day-to-day reality of a trial of labour feels much like any other monitored birth.

How VBAC works in a Singapore hospital

A planned VBAC in Singapore looks like a standard hospital birth with a few extra precautions. You will usually be encouraged to go into labour naturally rather than be induced too aggressively, because some methods of induction can raise the risk to the scar. Once you are in labour, your baby's heartbeat is monitored continuously, because changes in the heart rate are often the earliest sign of a problem with the scar.

Your team keeps a close eye on how labour is progressing. If contractions are effective and the baby is descending, you carry on toward a vaginal birth. If labour stalls, or if there are any worrying signs, your obstetrician may recommend switching to a caesarean. This flexibility is the whole point of a trial of labour: you attempt the vaginal birth in a setting where a surgical safety net is immediately available. Pain relief options are generally the same as for any other birth, and an epidural does not stop you from having a VBAC. If you are weighing up pain management, our overview of epidural and labour pain relief in Singapore explains what to expect.

Antenatal care for a VBAC pregnancy is much the same as any other, with the usual schedule of prenatal checkups and scans in Singapore, plus specific conversations about your birth preferences. Putting these preferences in writing helps your team support you on the day, and a structured birth plan is a good way to capture your wishes while staying flexible if circumstances change.

Planning your VBAC: practical steps

Good preparation makes a real difference to how confident you feel walking into the delivery suite. A few things are worth doing well before your due date:

• Request your first caesarean's operation notes so your scar type is confirmed, not assumed
• Choose an obstetrician and hospital that actively support VBAC and have emergency surgical cover
• Discuss your odds of success honestly, factoring in your history and this pregnancy
• Agree on a plan for induction or augmentation, since some methods are avoided in VBAC
• Decide in advance what would make you switch to a caesarean, so the choice is calmer in the moment
• Prepare for both outcomes emotionally, because a repeat caesarean is a safe and common result

If your VBAC ends in a repeat caesarean, your recovery will follow the usual path for surgical birth. It is worth reading up on what that involves ahead of time so nothing catches you off guard; our guide to caesarean recovery in Singapore covers healing, pain relief and what to expect in the first weeks.

Red flags and when to seek care

During a trial of labour, your hospital team is watching for early warning signs, but you should also know what to flag yourself. Tell your midwife or doctor immediately, or go to your hospital's delivery suite without delay, if you notice any of the following during labour or in the weeks leading up to it:

• Sudden, severe or constant abdominal pain that does not ease between contractions
• Pain over your old caesarean scar that feels sharp or tearing
• Vaginal bleeding that is heavy or bright red
• A noticeable drop in your baby's movements
• Feeling faint, dizzy, breathless or unusually unwell
• Signs that labour has slowed dramatically or stalled
• Any strong sense that something is not right, even if you cannot pinpoint it

These can be signs of a problem with the uterine scar or the placenta and need prompt assessment. Acting quickly is what keeps the rare complications of VBAC manageable, so never wait to see if a worrying symptom settles on its own.

Frequently asked questions

Is VBAC available in both public and private hospitals in Singapore?

Yes. Major public and private maternity hospitals in Singapore support VBAC for women who are medically suitable, because they have the continuous monitoring and emergency surgical facilities needed. What matters most is choosing an obstetrician who is comfortable supporting a trial of labour and discussing it with you early in your pregnancy.

What is my chance of a successful VBAC?

For most women with one previous low transverse caesarean, the success rate is roughly 60 to 70 percent. If you have also had a vaginal birth at some point, your chances rise to around 80 to 90 percent. Your obstetrician can give you a more personalised estimate based on the reason for your first caesarean and the details of this pregnancy.

How risky is uterine scar rupture during VBAC?

After one low transverse caesarean, the risk of the scar rupturing during labour is under 1 percent. It is a serious event, which is why VBAC is done with continuous monitoring in a hospital that can perform an emergency caesarean quickly. For eligible women, the overall risk profile of a planned VBAC is considered acceptable and is discussed in detail before you decide.

Can I have an epidural during a VBAC?

Yes. Having an epidural does not prevent a VBAC and does not hide the warning signs of scar problems, since those are mainly picked up through continuous monitoring of your baby's heartbeat and your symptoms. You can use the same pain relief options available in any hospital birth.

What happens if my VBAC does not work?

If labour stalls or any concerns arise, your team will recommend an unplanned caesarean. This is a safe and common outcome, not a failure on your part. The benefit of attempting a VBAC in a fully equipped hospital is that the surgical option is always immediately available if you need it.

The takeaway

VBAC is a realistic and well-supported option in Singapore for many women who had one caesarean. With a low transverse scar, a low-risk pregnancy and the right care team, the odds of a successful vaginal birth are good and the serious risks are uncommon. The key steps are confirming your scar type, choosing a supportive obstetrician and hospital, planning honestly for both outcomes, and knowing the warning signs to act on. Whatever path your birth takes, a safe delivery for you and your baby is the goal that matters most.
