What Does a VBAC Really Mean for You?
A VBAC stands for a vaginal birth after a cesarean, which means you can deliver vaginally if you previously delivered via a C-section. According to statistics, approximately 60% to 80% of VBAC cases are successful when carefully selected.The risk with VBAC is due to the scar on your uterus from previous surgery. It may lead to complications during labour, so your doctor will closely monitor labour progress and act accordingly.
Why Do Some VBAC Labours Turn into Emergency C-Sections?
The most common reasons for VBAC to turn into emergency C-sections are listed below.1. Uterine Rupture: The Most Serious Concern
A uterine rupture is a condition in which the old scar from your previous C-section tears open during intense contractions. This situation is very rare but has the highest risk levels during a VBAC. It occurs in about 0.5% to 1% of VBAC cases during labour. The following are the warning signs:
- Sharp pain between contractions
- Abnormal baby heart rate
- Sudden drop in contractions
2. Labour Not Progressing as Expected
Your cervix may not dilate fully, or your baby may take time to move down the birth canal in some cases. It can exhaust you. Your doctor may try other methods or use medications to make your labour progress. However, it may be of no help; therefore, an emergency C-section is often the best option in such cases.
3. Changes in Baby’s Heart Rate
A clear indication that your baby is handling labour well is their regular heart rate. A slow or erratic heart rate pattern may show that your baby is in distress. It means they are not getting enough oxygen. The reasons for this can be compression of the cord or strong contractions during labour.
Your doctor will act fast in such situations and go with an emergency C-section to prevent complications.
4. Placental Problems During Labour
The placenta provides vital elements to your baby, but it can also be the reason for problems.
- Placental abruption (when the placenta separates too early)
- Placenta previa (when the placenta covers the cervix)
5. Size or Position of the Baby
The position of your baby and their size matter when it comes to a vaginal birth. So, if they are awkwardly placed, such as a breech position (bottom-first) or transverse (sideways), vaginal delivery is unsafe. The baby may not fit your birth canal. Such situations demand a C-section for safe delivery.
6. Multiple Pregnancies or Health Conditions
VBAC is riskier if you are carrying twins or have conditions, such as gestational diabetes or high blood pressure. They can slow down your labour progress or cause distress to your baby. You may need a C-section to avoid complications for safe delivery.
How Can You Lower the Risk of an Emergency C-Section During VBAC?
You cannot control labour, but you can prepare your mind and body for a positive experience.- Ensure your hospital offers 24/7 surgical and neonatal support.
- Discuss whatever expectations you have from the delivery method with your doctor.
- Prepare physically for labour by staying active throughout the pregnancy.
- Gaining too much weight can increase the baby’s size, which may make VBAC harder.
- Maintain healthy blood pressure and sugar levels.
What Are the Warning Signs That Labour May Not Be Going Smoothly?
- Very sharp or constant abdominal pain
- Heavy vaginal bleeding
- Irregular baby heartbeat (usually monitored at the hospital)
- Your contractions stop suddenly
Emotional and Social Side of an Unplanned C-Section
A switch to a C-section from a VBAC may be emotionally draining. You may feel disappointed, but it is not a failure. Your birth story is unique based on the situation and the safety of your baby. Expressing your feelings can help you heal more quickly. Remember that your health and your baby’s safety always come first.
What Should You Do After an Emergency C-Section?
- You may take as much time as you need to recover, which is completely okay.
- Rest and refrain from rushing back into activities
- Eat healthy meals to support healing
- Take care of your incision

FAQs on What Causes VBAC Labours to Switch to Emergency C-Sections?
- How often do VBAC labours turn into emergency C-sections?
Almost 20% to 40% of VBAC cases may need an emergency C-section due to various reasons. Some of them are slow labour progress, medical history of complications, or deteriorating health conditions of the baby. - Is it risky to try for a VBAC after two C-sections?
The risk is higher, but it can be possible in some cases. Consult your doctor for a thorough evaluation of your scar, healing and overall health before considering a VBAC - Can emotional stress affect VBAC success?
