If your first baby was born via C-section, you might have a big question on your mind while expecting your second: "Will I be able to have a normal, vaginal birth this time?" This is a common hope for many mothers, often accompanied by a little bit of anxiety. Let’s talk about this clearly and simply today.
Then and Now: Has the perspective on birth after a C-section changed?
You might remember that in our mothers' generation, many believed that once you had a C-section, every subsequent baby had to be delivered by C-section as well. Even doctors often recommended this back then, and there were reasons for it.
However, modern medicine has advanced significantly. With new research and knowledge, many things have changed. Today, doctors acknowledge that many eligible mothers who have had a previous C-section can successfully have a Vaginal Birth After Cesarean (VBAC). In fact, this is now considered a safe option for many mothers and their babies.
Think about it: with a normal birth, you can go home sooner. There is less physical discomfort, and you can recover faster. These are some of the biggest advantages of a VBAC.
So, can I have a VBAC? What does it depend on?
This is the most important question. It is not the same for everyone. Several factors determine whether you can have a VBAC. Let’s look at them one by one.
1. What was the reason for your first C-section?
Sometimes the first surgery might have been due to an emergency with the baby or a maternal issue like high blood pressure. If the reason for the first C-section is likely to recur in this pregnancy, a VBAC might be risky. However, some reasons were specific only to that time. For example, if you had a C-section because the baby was in a breech position, and the baby is in the correct position this time, there is a higher chance of attempting a VBAC. Your doctor will be able to explain this clearly to you.
2. Type of Uterine Incision – This is the most important factor!
This is something you need to be very careful about. The type of incision made on your uterus during your first C-section is critical for a VBAC. We are not talking about the scar visible on your skin, but the incision made on the uterus itself.
We generally talk about two types of incisions:
- Low-transverse incision:
Simply put, this is the most common type and the most favorable for a VBAC. This incision is made horizontally in the lower, thinner part of the uterus. Think of it like a bikini line (not the skin incision, but the uterine one). Because of its location, this area does not undergo as much pressure when the uterus contracts during labor. Therefore, a mother with this type of incision has a much higher chance of a successful VBAC.
- Vertical incision:
In this case, the incision is made vertically from the top to the bottom of the uterus. Because this incision goes through the uterine muscles, there is a higher risk of uterine rupture when the uterus contracts strongly during labor. This can be a very dangerous situation for both mother and baby. Therefore, if you have a vertical incision (especially a "classical" incision in the upper part of the uterus), doctors generally do not recommend attempting a VBAC.
Important: Even if your skin incision is horizontal, sometimes the uterine incision might be vertical. Therefore, it is essential to check your surgical notes from your first C-section to know exactly what kind of uterine incision was made. Discuss this with your doctor.
3. How many C-sections have you had?
While we talk about VBAC after one C-section, attempting a VBAC after two or more C-sections can be slightly riskier. Due to increased scar tissue in the uterus, the risk of uterine rupture may be higher. However, in some special cases, even those who have had two previous C-sections may be allowed to attempt a VBAC in a suitable facility with extreme caution. This depends entirely on your medical history, the type of uterine incision, and the decision of your doctor.
4. Your current pregnancy status and other health issues
If you have conditions like Diabetes Mellitus or high blood pressure during this pregnancy, if there are concerns about the baby's growth, or if the baby appears to be very large (macrosomia), your doctor might reconsider a VBAC. Additionally, any issues with the shape of your uterus (e.g., fibroids) can also influence the decision.
Are there no risks at all with a VBAC?
Although a VBAC is a safe option for many mothers, it is not without risks. The main risk is uterine rupture. This occurs when the uterine wall tears at the site of the previous C-section scar. This is very rare (less than 1% in Sri Lanka, especially for those with a transverse incision), but if it happens, it can be an emergency for both mother and baby. That is why it is said that if you are attempting a VBAC, it should be done in a hospital that has all the facilities for an emergency C-section.
On the other hand, if you attempt a VBAC and it is not successful, you may end up needing an emergency C-section. In such an unplanned emergency surgery, the risk of minor complications may be slightly higher compared to a scheduled C-section.
Don't be afraid! We mentioned these risks to inform you, not to scare you. Many mothers successfully have a VBAC without any issues. The most important thing is to discuss with your doctor whether it is suitable for your condition, what the risks are, and what the benefits are, and then make a decision.
If I want a VBAC, what should I do?
If you are considering a VBAC, follow these steps:
1. Talk to your doctor: This is the first and most important step. Discuss your previous C-section details (especially the type of uterine incision) and your current health status. Ask clearly about the benefits, risks, and any specific concerns you might have. Your doctor will examine you, review your records, and advise you on whether a VBAC is suitable for you.
2. Check with the hospital where you plan to deliver: Not all hospitals have the same facilities or policies for VBAC. Some hospitals support VBACs and have emergency units and operating theaters available 24/7. However, some smaller hospitals may not allow VBACs due to limited resources in case of an emergency. Therefore, it is very important to know the VBAC policy of your chosen hospital in advance.
3. Prepare yourself, but be flexible:
Even if you have prepared yourself for a VBAC, sometimes things do not go as planned. If a complication arises during labor, your doctor may decide that an emergency C-section is necessary. Remember, the ultimate goal is a healthy mother and a healthy baby. Therefore, be prepared to follow your doctor's advice.
Consider this: if the hospital you have chosen does not allow VBACs, but you have a strong desire for one and your doctor agrees, you may be able to transfer to a hospital that offers VBAC facilities. Discuss this possibility with your doctor as well.
Let’s summarize what we discussed (Take-Home Message)
Alright then, here are the most important points you should remember from what we have discussed:
- Even if you have had a previous C-section, many mothers are able to have a normal delivery (VBAC). It is now considered a safe option.
- The main factor in determining whether a VBAC is possible is the type of uterine incision made during your first C-section. A transverse incision is the most favorable.
- Factors such as the reason for your first C-section, the number of previous C-sections, and your current health status also play a role.
- There may be minor risks associated with a VBAC, but with a good plan and a skilled medical team, these risks can be minimized.
- The most important thing is to talk openly with your doctor about this. They are the ones who will advise you on what is best for your specific situation.
- Be sure to inform yourself in advance about the VBAC policy of the hospital where you plan to give birth.
Remember, every pregnancy and every delivery is unique. I wish you the strength to choose what is safest and healthiest for both you and your baby!
