The mode of birth is one of the questions most often asked during pregnancy. Vaginal birth and caesarean section are two different methods, each preferred under specific medical circumstances. This article compares them objectively and explains the criteria on which the decision is based.
Vaginal birth
In vaginal birth the baby passes through the birth canal with the help of uterine contractions. Labour has three stages: dilation of the cervix, birth of the baby and delivery of the placenta. In first births the active phase may last 8–12 hours on average; later births are usually shorter. Epidural anaesthesia, breathing techniques and changes of position can be used for pain relief. Assisted vaginal birth with vacuum or forceps may be performed when needed.
Caesarean birth
Caesarean section is the surgical delivery of the baby through an incision in the abdominal and uterine wall. It is usually performed under spinal or epidural anaesthesia, with the mother awake. It may be planned (elective) or performed as an emergency because of a problem arising during labour. The operation takes about 45–60 minutes and the hospital stay is usually 2–3 days.
When is a caesarean medically necessary?
- Placenta covering the cervix (placenta praevia)
- Breech or transverse presentation when no other option is suitable
- Labour that fails to progress or signs of fetal distress
- Some multiple pregnancies
- Previous uterine surgery or certain previous caesarean histories
- Maternal conditions that preclude labour (severe pre-eclampsia, active genital herpes, etc.)
Comparison
| Topic | Vaginal birth | Caesarean |
|---|---|---|
| Recovery | Usually a few days to 2 weeks | Usually 4–6 weeks |
| Hospital stay | 1–2 days | 2–3 days |
| Main risks | Perineal tears, bleeding, rarely pelvic floor problems | Infection, bleeding, thrombosis, anaesthetic risks, placental problems in later pregnancies |
| Next birth | High likelihood of vaginal birth | Vaginal birth after caesarean (VBAC) may be considered in suitable cases |
| For the baby | Transient breathing problems less common | Transient breathing problems slightly more common after planned early caesarean |
How is the decision made?
The World Health Organization recommends that caesarean section be performed only when medically necessary; in pregnancies without a medical indication, vaginal birth is the preferred option. The decision is made jointly by the physician and the expectant mother, taking into account the findings gathered during antenatal care, the mother’s health and her preferences. An open discussion of the risks and benefits of both methods is part of preparing for birth.
Preparing for birth
- Attend all antenatal check-ups
- Take part in antenatal classes
- Discuss your birth plan and preferences with your physician in advance
- Plan support for the postpartum period
