If you had a Caesarean section (C-section) before, it does not mean that you will have to deliver again the same way. Many women can have vaginal deliveries after having a C-section in the past. This is called a vaginal birth after cesarean (VBAC).
Most women who try VBAC are able to deliver vaginally. If you can have a VBAC, there are many good reasons to try it rather than have a C-section. Some are:·
The most serious risk with VBAC is rupture (break) of the uterus. Blood loss from a rupture can be a risk for the mom and can cause damage to the baby.
Women who try VBAC and do not succeed are also more likely to need a blood transfusion. There is also a greater risk of getting an infection in the uterus.
The chance of a rupture depends on how many and what kind of C-section you had before. You may be able to have a VBAC if you have had no more than one C-section deliveries in the past. But that is not all.
Your doctor will want to make sure your pelvis is large enough for a vaginal birth and monitor to see if you have a big baby. It may not be safe for the baby to pass through the pelvis.
Since problems can occur quickly, where you plan to have your delivery is also a factor.
You and your doctor will decide if a VBAC is right for you. Talk with your health care provider about the risks and benefits for you and your baby.
Every woman’s risk is different, so ask what factors matter most for you. The more you know about VBAC, the easier it will be to decide if it is right for you.
If your doctor says that you can have a VBAC, chances are good that you can have one with success. Around 3 out of 4 women who try VBAC are able to deliver vaginally.
Keep in mind, you can try for a VBAC, but you may need a C-section anyway.
