Exercise and Activity During Pregnancy with Uterine Fibroids
You can and should exercise during pregnancy despite having three myomas—there are no specific activity restrictions required solely due to the presence of uterine fibroids. The fibroids themselves do not contraindicate physical activity unless you develop specific complications 1, 2.
Recommended Exercise Guidelines
For uncomplicated pregnancies (which includes pregnancies with asymptomatic fibroids), you should aim for:
- 150 minutes per week of moderate-intensity aerobic exercise spread over at least 3 days 1, 3
- Pelvic floor and muscle strengthening exercises 4, 5
- Activities can include walking, swimming, stationary cycling, and modified strength training 6, 1
The evidence strongly supports that exercise during pregnancy provides significant benefits including decreased risk of gestational diabetes, cesarean delivery, and faster postpartum recovery 1. Importantly, activity restriction and bed rest are not only unhelpful but actually harmful, causing deconditioning, bone loss, increased blood clot risk, and psychological stress 7.
Activities to Avoid
Regardless of fibroid presence, all pregnant women should avoid:
- High-risk activities with potential for abdominal trauma (contact sports, activities with high fall risk) 6
- Scuba diving (increased fetal risk for decompression sickness) 6
- Exercises in supine position after first trimester 4
Warning Signs to Stop Exercise Immediately
Cease activity and contact your healthcare provider if you experience:
- Vaginal bleeding
- Persistent dizziness or headache
- Chest pain or shortness of breath at rest
- Regular painful contractions
- Amniotic fluid leakage
- Calf pain or swelling 4, 1
Fibroid-Specific Considerations
While fibroids are common in pregnancy and most remain asymptomatic 8, you should maintain close surveillance with your obstetrician. The fibroids may cause:
- Increased uterine size leading to pressure symptoms
- Potential pain if fibroid degeneration occurs
- Possible impact on fetal position as pregnancy progresses 8
However, none of these potential complications require preemptive activity restriction. Only if you develop specific complications (such as threatened preterm labor, placenta previa after 28 weeks, or preeclampsia) would activity modification be considered 7, 2.
Common Pitfall to Avoid
The most important pitfall is unnecessary activity restriction. Many clinicians still recommend bed rest or activity limitation despite strong evidence showing this causes more harm than good 7. Unless you develop a specific obstetric complication with clear contraindications, you should maintain regular physical activity throughout your pregnancy 1, 3.
Your pregnancy with fibroids requires tailored surveillance for potential complications, but the presence of myomas alone does not justify limiting your normal activities or exercise routine 8.
