# Vaginal Birth After Caesarean and What to Consider Beforehand
Imagine a woman who ended up in the operating room during her first delivery. A cesarean section was necessary, everything went well, and she is holding a healthy baby in her arms. Two years later, she is pregnant again and faces a question that occupies her more than anything else: Will I have another cesarean, or will I try to give birth naturally? This situation is not unusual – and the decision she faces is among the most serious any expectant mother can make.
Vaginal birth after a previous cesarean section, referred to in medical terminology by the abbreviation VBAC (from the English vaginal birth after cesarean), is a topic that resonates ever more loudly in obstetrics. While just a few decades ago the rule was "once a cesarean, always a cesarean," modern medicine has significantly revised this view. Today, VBAC is in many cases not only possible but, under the right conditions, also recommended. Nevertheless, it is a decision that requires careful consideration of a whole range of factors – medical, psychological, and practical.

Why even consider natural birth after a cesarean?
The answer to this question is not simple, because every woman's motivations are different. Some long for the natural birth experience that was denied to them with their first child. Others want to avoid the longer recovery after surgery, which complicates caring for a newborn as well as older siblings. Still others are guided by scientific findings about the benefits of vaginal birth for the child's health – passage through the birth canal has a positive effect on the newborn's microbiome and immune system, as documented by studies published in Nature Medicine, for example.
A repeat cesarean section carries its own risks, which increase with each subsequent procedure. These include adhesions in the abdominal cavity, placental complications such as placenta praevia or placenta accreta, longer hospitalization, and more difficult recovery. For women planning a larger family, the question of VBAC is therefore particularly relevant – each additional cesarean complicates the situation for any future pregnancies.
On the other hand, it cannot be overlooked that VBAC is not without risks. The most serious is uterine rupture, meaning the tearing of the scar from the previous incision. This is a rare but life-threatening complication that requires immediate surgical intervention. According to data from the American College of Obstetricians and Gynecologists (ACOG), it occurs in approximately 0.5 to 0.9% of VBAC attempts – that is, in approximately one woman in two hundred. This figure is important to know, but it must be understood in the context of the overall health profile of the individual woman.
For whom might VBAC be suitable, and for whom not?
Every woman considering VBAC should have a detailed consultation with her gynecologist or obstetrician. There are situations in which VBAC is an appropriate choice, and situations in which it is contraindicated. Among the factors physicians evaluate are the type of scar from the previous cesarean section, the reason it was performed at the time, the mother's overall health, the course of the current pregnancy, and where and with what support the woman plans to give birth.
The most favorable conditions for VBAC exist for a woman who has a single transverse scar on the lower uterine segment – this type of incision is associated with the lowest risk of rupture. A vertical scar or a T-shaped scar, on the other hand, significantly increases the risk, and VBAC is generally not recommended in such cases. Equally important is whether the previous cesarean was planned or emergency – if it was performed for a reason that will not recur in the next pregnancy (such as incorrect fetal position), the prospects for a successful VBAC are more favorable than in cases where the cesarean was indicated due to failure to progress in labor.
The mother's age, weight, height, and pelvic shape, the size of the baby, and the interval between deliveries – all of these play a role. Experts recommend that at least 18 months pass between the last cesarean and the next delivery, ideally two years, to allow the scar sufficient time to heal. Women with more than two previous cesarean sections are considered less suitable candidates for VBAC, although exceptions exist even in these cases.
A crucial role is also played by whether the maternity hospital where the woman plans to give birth is equipped to handle potential complications. VBAC should take place exclusively at a facility with continuous surgical readiness on hand, meaning the ability to perform an emergency cesarean section within 30 minutes. This condition automatically rules out the possibility of a planned home birth or birth at birthing centers without surgical facilities.
As a practical example, consider a thirty-year-old woman who gave birth by cesarean two years ago because the baby was in a breech position. She is now expecting her second child, who is lying head-down, the scar has healed well, the interval between deliveries is sufficient, and the maternity hospital where she plans to give birth has continuous surgical readiness. In such a case, the probability of a successful VBAC is relatively high – expert studies report success rates between 60 and 80 percent in appropriately selected women.
The psychological and emotional side of decision-making
Medical criteria are important, but they are not the only ones. The decision about the method of delivery has a profound psychological dimension that is sometimes overlooked in professional discussions. Women who experienced their previous delivery as traumatic – whether it involved an unplanned last-minute cesarean or a feeling of loss of control – may have very strong reasons to want to give birth differently this time. Conversely, women who were satisfied with their cesarean and felt safe may have natural concerns about venturing into the unknown.
As midwife and author of numerous books on natural childbirth Ina May Gaskin said: "A woman's body is not a defective machine, and natural birth is not a dangerous activity." These words are not a call to gamble with one's health, but a reminder that trust in natural processes has its place – and that fear itself can be an obstacle.
Psychological preparation for VBAC involves not only learning about the risks and benefits, but also processing the previous birth experience. Many women benefit from speaking with a psychologist specializing in perinatal care or from participating in groups for women who have had cesarean sections. The support of a partner, family, and midwife is invaluable throughout – research repeatedly confirms that continuous support during labor increases the likelihood of a successful vaginal birth and reduces the need for medical interventions.
It is also important to set realistic expectations. VBAC is not a guarantee of a "perfect" birth – it can be painful, complicated, and may ultimately end in a repeat cesarean. Women who are prepared for this possibility and do not perceive it as a personal failure cope with the entire process better than those for whom an emergency cesarean would be a traumatic disappointment.
What to specifically prepare for
Preparation for VBAC should ideally begin even before conception, or at least in the first trimester. Choosing a maternity hospital and birth team with experience in and a positive attitude toward VBAC is key. Not all facilities actively support VBAC – some formally allow it but in practice pressure women toward a repeat cesarean. It is therefore worthwhile to find out in advance the maternity hospital's statistics, its approach to VBAC, and how the specific physicians and midwives approach this topic.
During pregnancy, it is advisable to:
- Regularly consult on the course of the pregnancy with a physician and speak openly about your wishes and concerns
- Determine the type and condition of the scar – ideally from the medical records of the previous delivery
- Attend a prenatal class focused on natural birth and pain management techniques
- Learn about pain relief options – epidural anesthesia is safe during VBAC and its use does not increase the risk of rupture in any way
- Draw up a birth plan that is realistic and accounts for various scenarios
The actual course of labor during VBAC requires careful monitoring. Both the baby and the scar are continuously monitored using cardiotocography so that any warning signs can be detected promptly. The woman should know what symptoms may indicate complications – for example, sudden severe pain in the area of the scar, a change in the character of contractions, or deterioration of the baby's condition on the monitor.
The entire process is demanding, but for many women it is deeply meaningful. Vaginal birth after a cesarean is not merely a medical choice – it is also an act of self-confidence and informed decision-making that can transform not only the birth itself, but also how a woman perceives herself as a mother. Whether the decision ultimately leans toward VBAC or a planned repeat cesarean, the most important thing is that it be made consciously, with sufficient information, and in an environment where the woman feels safe and respected. Because every birth is unique – and every woman deserves to have her voice heard in this decision.
