For most women, labour begins naturally somewhere between 37 and 42 weeks. Your body gradually prepares: the cervix softens and opens, contractions build, and the waters may break. When this process starts on its own, we call it spontaneous labour.
But sometimes, waiting for nature to take its course isn’t the safest option. That’s when doctors may recommend induction of labour—a medically supported way to help your body begin the process.
Induction is common, carefully monitored, and designed with one goal in mind: a safe birth for you and your baby.
Why induction may be recommended
Induction is not about rushing birth—it’s about balancing safety, timing, and wellbeing. Your doctor may suggest it if:
• You have high blood pressure or another health concern that makes continuing the pregnancy risky.
• Your pregnancy has gone past your due date.
• Your baby’s movements have reduced, fluid levels are low, or growth is slowing.
• Your waters have broken, but contractions haven’t started.
Each of these situations carries its own considerations, but the principle is the same: when the risks of waiting outweigh the benefits, induction becomes the safer path.
How doctors decide the best method
Before induction begins, your doctor performs a vaginal examination to assess how 'ready' your cervix is. This is often called the Bishop score, though you won’t hear that jargon in the labour room. What matters is whether the cervix is soft, thin, and slightly open—or still firm and closed.

Based on this, one or more of the following methods may be used.
Methods of Induction
Prostaglandins
Prostaglandins are hormones that help soften and open the cervix. A synthetic version is placed in the vagina as a gel or a small pessary. You’ll stay in the hospital so your baby can be monitored. Some women need more than one dose. Once the cervix responds, the next stage of induction can begin.
Balloon catheter
If prostaglandins aren’t suitable—such as after a previous caesarean—a balloon catheter may be used. A thin tube with a small balloon is placed inside the cervix and gently inflated. The pressure encourages the cervix to open. It usually stays in for several hours until it falls out or your doctor removes it.
Artificial rupture of membranes (ARM)
If your cervix is already slightly open, your doctor may “break the waters” using a small instrument during an examination. Sometimes contractions begin naturally afterwards. If not, the next step is oxytocin.
Oxytocin infusion
Oxytocin is the hormone that drives contractions. A synthetic version is given through a drip in your arm. The dose is gradually increased until contractions become strong and regular. Your baby’s heart rate is monitored throughout to ensure they are coping well.
What to expect during the process?
Induction can be quick for some women and slow for others. It may involve one method or a combination. It’s normal to feel uncertain or even anxious—this is a big moment. But you’ll be supported throughout, and every step is taken with your safety in mind.
Possible Risks and Challenges
When induction doesn’t work
Sometimes the cervix doesn’t open despite prostaglandins or a balloon catheter. If that happens, your doctor may suggest trying another method, waiting longer, or considering a caesarean section.
Similarly, after the waters are broken, contractions may still not start. In that case, a caesarean may again be the safest option.
Over‑stimulation of the uterus
Synthetic hormones can occasionally cause contractions that are too strong or too frequent. This can stress both mother and baby. If this happens, the hormone dose is reduced, stopped, or medication is given to relax the uterus.
Does induction increase the chance of interventions?
Modern studies show that when induction is done for the right reasons and managed well, it does not increase the likelihood of caesarean birth. Still, every woman’s situation is unique, and your doctor will help you weigh the benefits and risks.

Making the decision that’s right for you
Some women prefer to wait for labour to start naturally. Others feel more comfortable choosing induction once they understand the reasons. There is no “one right answer”—only the answer that fits your health, your baby’s wellbeing, and your comfort.
Here are helpful questions to ask your doctor:
• Why induction in my case?
• Risks of waiting if I choose to wait?
• Risks of induction for my baby and me?
• What to expect during the process?
Induction of labour is not about forcing your body—it’s about guiding it safely when nature needs a little help. With clear information, supportive care, and shared decision‑making, you can approach induction with confidence and calm.
