Fibroids During Pregnancy: Causes, Risks, Symptoms & Safe Treatment Options

Fibroids During Pregnancy: Causes, Risks, Symptoms & Safe Treatment Options

Pregnancy is a beautiful yet sensitive phase in a woman’s life. However, certain medical conditions can make this journey more complex. One such common condition is fibroids during pregnancy. Many women are diagnosed with fibroids either before conceiving or during routine pregnancy ultrasounds, which can naturally cause anxiety.

The good news is that most women with fibroids have a healthy pregnancy and safe delivery with proper medical care and monitoring. In this detailed guide, we will explain everything you need to know about fibroids during pregnancy, including causes, symptoms, risks, diagnosis, and treatment options.

Fibroids During Pregnancy

What Are Fibroids?

Fibroids, also known as uterine fibroids or leiomyomas, are non-cancerous growths that develop in or around the uterus. They are made of muscle and fibrous tissue and can vary greatly in size—from very small (pea-sized) to large masses.

Fibroids are common in women of reproductive age and often go unnoticed unless they cause symptoms or complications.

Fibroids During Pregnancy: An Overview

Fibroids during pregnancy occur when a woman already has fibroids before conceiving or when fibroids are detected during pregnancy ultrasounds. Due to hormonal changes—especially increased estrogen and progesterone—fibroids may grow during pregnancy, particularly in the first and second trimesters.

However, not all fibroids grow during pregnancy. Some remain the same size or may even shrink after delivery.

Types of Fibroids That Can Affect Pregnancy

Understanding the type and location of fibroids is crucial because it determines the level of risk during pregnancy.

1. Intramural Fibroids

  • Grow within the uterine wall

  • Most common type

  • Can sometimes affect uterine expansion during pregnancy

2. Submucosal Fibroids

  • Grow inside the uterine cavity

  • Higher risk of complications

  • Can affect implantation and fetal growth

3. Subserosal Fibroids

  • Grow on the outer surface of the uterus

  • Usually cause fewer pregnancy-related issues

4. Pedunculated Fibroids

  • Attached by a stalk

  • May cause pain if twisted during pregnancy

Causes of Fibroids During Pregnancy

The exact cause of fibroids is still unknown, but several factors increase the risk:

  • Hormonal imbalance (estrogen dominance)

  • Genetic predisposition

  • Obesity

  • Late pregnancy (after 30 years)

  • Family history of fibroids

  • Early onset of menstruation

During pregnancy, elevated hormone levels may stimulate fibroid growth, especially in the early months.

Common Symptoms of Fibroids During Pregnancy

Many women experience no symptoms at all, but some may notice the following:

  • Pelvic pain or pressure

  • Lower back pain

  • Abdominal discomfort

  • Frequent urination

  • Constipation

  • Pain during movement

  • Severe pain due to fibroid degeneration (red degeneration)

⚠️ Severe pain, bleeding, or contractions should always be reported to your gynecologist immediately.

How Are Fibroids Diagnosed During Pregnancy?

Fibroids during pregnancy are usually detected through:

  • Routine ultrasound scans

  • Pelvic examination (limited during pregnancy)

  • MRI (rarely required)

Ultrasound helps determine:

  • Size of fibroids

  • Location

  • Impact on the fetus or placenta

Risks and Complications of Fibroids During Pregnancy

While many pregnancies progress normally, fibroids can sometimes increase the risk of complications, depending on their size and location.

Possible Risks Include:

  • Miscarriage (especially with submucosal fibroids)

  • Preterm labor

  • Placental abruption

  • Fetal growth restriction

  • Abnormal fetal position (breech)

  • Prolonged labor

  • Increased chances of C-section

  • Postpartum hemorrhage

That said, most women with fibroids still deliver healthy babies under expert medical supervision.

Do Fibroids Affect Normal Delivery?

Fibroids do not automatically mean a C-section. Many women with small or medium-sized fibroids can have a normal vaginal delivery.

However, a C-section may be recommended if:

  • Fibroids block the birth canal

  • Baby is in abnormal position

  • Fibroids cause severe complications

Your delivery plan is always individualized based on your condition.

Treatment Options for Fibroids During Pregnancy

1. Conservative Management (Most Common)

  • Regular monitoring

  • Pain management with pregnancy-safe medications

  • Bed rest if needed

2. Pain Management

  • Mild analgesics prescribed by the doctor

  • Hydration and rest

  • Avoiding strenuous activities

3. Surgery During Pregnancy (Rare)

  • Myomectomy during pregnancy is avoided unless life-threatening complications arise

⚠️ Fibroid removal is usually postponed until after delivery.

Can Fibroids Shrink After Pregnancy?

Yes. In many cases, fibroids shrink naturally after childbirth due to a decrease in hormone levels. Breastfeeding can further help reduce estrogen levels, contributing to fibroid shrinkage.

Importance of Regular Gynecologist Visits

If you are diagnosed with fibroids during pregnancy, regular prenatal check-ups become even more important. Close monitoring helps prevent complications and ensures timely intervention if needed.
