Induction at 41 WeeksInduction may be recommended at 41 weeks for various reasons.
Medical vs Elective InductionInductions are performed for medical reasons or they are elective. Elective inductions may also be motivated by medical concerns.
- Medical indications Induction may be necessary if there is a medical risk for mother or for baby.
- Elective induction of labor
If there is no immediate medical risk but there is an ongoing medical concern which could be alleviated by baby's delivery, then induction is likely to be recommended. Other reasons for elective induction include scheduling issues and concerns about getting to hospital in time.
Your medical practitioner should discuss with you the benefits and risks of expectant management versus induction.
