Can You Have a Normal Delivery with Fibroids? What Experts Say

Three Key Factors Determining Delivery Method

Your obstetrician will monitor your pregnancy closely via ultrasound to decide on the safest delivery method. According to experts like Dr. Aarti Deendayal, the decision often comes down to three critical variables.

1. Location of the Fibroid

This is arguably the most critical factor in determining your birth plan.

• Upper Segment Fibroids: If the fibroid is located at the top (fundus) or the sides of the uterus, it usually poses no threat to a vaginal delivery. It stays out of the way as the baby moves down.
• Lower Segment (Cervical) Fibroids: If a fibroid is located near the cervix (the neck of the womb), it can physically block the birth canal. In this scenario, the baby cannot exit the uterus safely, and a planned C-section becomes mandatory.

2. Size of the Fibroid

Size matters, but often less than location.

• Small Fibroids (<5 cm): These rarely cause issues during labour. Most women with small fibroids experience no difference in their delivery compared to women without them.
• Large Fibroids (>5 cm): Larger fibroids can compete for space in the uterus. They may prevent the baby from getting into the optimal head-down position or impair the uterus’s ability to contract effectively.

3. Number of Fibroids

While a single fibroid is usually manageable, distinct clusters of multiple fibroids (poly-fibroid uterus) can make the uterine wall rigid. This rigidity can prevent the strong, rhythmic contractions needed to push the baby out, potentially stalling labour.

Problems You Might Face During Labour

Even if your doctor clears you for a vaginal trial of labour, fibroids can introduce specific complications that you should be aware of. Being prepared helps you and your medical team manage these situations effectively.

Labour Dystocia (Slow Labour)

The uterus is a muscle, designed to contract and push. Fibroids, however, are made of fibrous tissue that does not contract. If a large portion of the uterine wall is taken up by fibroids, the uterus may struggle to contract strongly enough to dilate the cervix. This can lead to “failure to progress,” which is a common reason for unplanned C-sections.

Fetal Malpresentation

Ideally, a baby turns head-down (cephalic) by 36 weeks. Large fibroids can crowd the uterine cavity, restricting the baby’s movement. This increases the likelihood of:

• Breech presentation: Where the baby’s buttocks or feet are positioned to come out first.
• Transverse lie: Where the baby lies sideways across the uterus.

In these cases, a C-section is often the safest option for both mother and baby.

Placental Abruption

In rare cases, complications arise regarding the placenta. If the placenta implants directly over a large fibroid, the blood supply can be compromised. This increases the risk of placental abruption—where the placenta detaches from the uterine wall prematurely. This is a medical emergency requiring immediate delivery.

After the Baby is Born

The risk doesn’t end the moment the baby is born. Fibroids can impact your recovery in the hours following delivery, so close monitoring is essential.

Postpartum Haemorrhage (PPH)

After the baby is delivered, the uterus must clamp down hard to stop bleeding from where the placenta was attached. Fibroids can physically prevent this clamping action, leading to heavier blood loss. At Mamata Fertility Hospital Hyderabad, the medical team is always prepared with specific medications to manage this risk effectively.

Increased Cramping

You might experience stronger “afterpains” (cramps as the uterus shrinks back to size) compared to women without fibroids. This is because the uterus has to work harder to contract around the fibroids.

Fibroid Shrinkage

There is a silver lining. Due to the sudden drop in hormones (estrogen and progesterone) post-birth, many fibroids shrink significantly in the months following delivery.

When is a C-Section Mandatory?

While doctors generally prefer vaginal delivery due to the quicker recovery time, a C-section is non-negotiable in certain scenarios to ensure safety:

1. Obstruction: The fibroid is blocking the cervix, making it impossible for the baby to pass through.
2. Prior Myomectomy: If you have had previous surgery to remove fibroids where the uterine cavity was entered, the risk of uterine rupture during labour is higher. A C-section is usually scheduled to prevent this.
3. Fetal Distress: If the baby shows signs of stress during labour, an emergency C-section will be performed.

Frequently Asked Questions

To ensure you have a complete picture, here are answers to the most common questions patients ask about fibroids and pregnancy.

Do fibroids grow during pregnancy?

They can. Due to the massive surge in estrogen and progesterone, about one-third of fibroids may grow, typically in the first trimester. However, the majority remain the same size, and some even shrink. Regular scans will track any changes.

Can fibroids cause miscarriage?

There is a slightly increased risk of miscarriage or preterm labour with fibroids, particularly if they are large or located inside the uterine cavity (submucosal). However, it is important to remember that the vast majority of pregnancies with fibroids proceed safely to full term.

Will the doctor remove the fibroid during my C-section?

Generally, the answer is no. The uterus has massive blood flow during pregnancy. Removing a fibroid during a C-section (Cesarean Myomectomy) carries a very high risk of uncontrollable bleeding. Doctors usually advise waiting until you have fully recovered from birth to address the fibroids surgically if they are still causing issues.

Is it painful to carry a baby with fibroids?

Some women experience “red degeneration,” which happens when a fibroid outgrows its blood supply and starts to die off. This can cause localised pain. This is usually managed with rest, hydration, and safe pain relief prescribed by your doctor.

Conclusion

A diagnosis of fibroids does not define your birth story. With regular monitoring and a skilled medical team, a normal, healthy delivery is a very real possibility for most women.

The key is open communication with your OB-GYN to track the growth and location of the fibroids as your baby grows. Whether you deliver vaginally or via C-section, the ultimate goal is a healthy mum and a healthy baby.
