What are Intramural Fibroids?

Intramural fibroids are benign growths of smooth muscle and connective tissue that develop within the muscular wall (myometrium) of the uterus. They are a common type of uterine fibroid and may occur as a single growth or as multiple fibroids. Some intramural fibroids do not cause symptoms, while larger or multiple fibroids may contribute to heavy or prolonged menstrual bleeding, pelvic pressure, abdominal or back pain, urinary symptoms and reproductive difficulties. Symptoms depend on the size, number, and location of the fibroids and whether they distort the uterine cavity.

What is the Importance of Timely Treatment?

Timely evaluation can help determine the size, number and location of intramural fibroids and whether they are contributing to symptoms such as heavy menstrual bleeding, anemia, pelvic pressure or fertility problems. Asymptomatic fibroids may only require observation, whereas symptomatic or enlarging fibroids may require medication, minimally invasive procedures or surgery. Early assessment also helps identify other causes of abnormal uterine bleeding or pelvic symptoms and allows treatment to be selected according to reproductive plans and individual preferences.

What are the Common Symptoms of Intramural Fibroids?

  • Heavy or prolonged menstrual bleeding
  • Menstrual bleeding between periods
  • Painful menstrual periods
  • Pelvic pressure or a feeling of fullness
  • Lower abdominal or pelvic pain
  • Lower back pain
  • Abdominal enlargement or fullness
  • Frequent urination or difficulty emptying the bladder when a fibroid presses on the urinary tract
  • Constipation or rectal pressure in larger fibroids
  • Pain during sexual intercourse
  • Fatigue or weakness related to iron-deficiency anemia from heavy bleeding
  • Difficulty conceiving in some patients
  • Pregnancy-related complications in selected cases

Causes and Risk Factors of Intramural Fibroids

Causes

  • The exact cause of intramural fibroids is not completely understood. They develop from abnormal growth of smooth muscle cells within the uterine wall and are influenced by genetic and hormonal factors.
  • Oestrogen and progesterone contribute to fibroid growth, which is why fibroids commonly develop during the reproductive years and often shrink after menopause.
  • Genetic changes within uterine cells may also contribute to their development.

Risk Factors

  • Increasing reproductive age, particularly during the years when fibroids are most likely to develop
  • Family history of uterine fibroids
  • Genetic or cellular factors associated with fibroid development
  • Overweight or obesity
  • Hormonal exposure during the reproductive years
  • Early onset of menstruation
  • Certain population and genetic factors
  • Increasing age before menopause
  • Factors associated with metabolic and hormonal health

Latest Research and Technologies in the Treatment of Intramural Fibroids in Singapore

Recent advances in intramural fibroid treatment in Singapore include ultrasound-guided high-intensity focused ultrasound (USgHIFU), a non-invasive technique that uses focused ultrasound energy to destroy fibroid tissue while preserving the uterus. MRI-guided focused ultrasound and uterine artery embolisation are other uterus-preserving options for selected patients, with suitability depending on fibroid characteristics, symptoms, and future pregnancy plans.

Treatment options for Intramural Fibroids

Myomectomy : Myomectomy removes fibroids while preserving the uterus and may be considered for patients with significant symptoms or selected fertility-related concerns. Depending on fibroid size and location, it may be performed through laparoscopic, robotic or open surgery.

Uterine Artery Embolisation: UAE is a minimally invasive procedure in which small particles are introduced through the uterine arteries to reduce blood flow to the fibroid, causing it to shrink over time. It can provide a uterus-preserving treatment option for appropriately selected patients, although its suitability should be discussed carefully in patients who wish to become pregnant.

Hysterectomy : Hysterectomy removes the uterus and provides definitive treatment for uterine fibroids. It may be considered when symptoms are severe, other treatments are unsuitable or unsuccessful, or the patient does not wish to preserve fertility. The decision depends on individual circumstances and preferences

  • Clinical assessment:
    • Gynecological Evaluation: A detailed medical and menstrual history assesses bleeding pattern, pelvic pain, pressure symptoms, urinary or bowel symptoms, reproductive history, fertility concerns and previous treatment. Pelvic examination may help identify an enlarged or irregular uterus.
    • Assessment of Menstrual Blood Loss and Anemia: Complete blood count and iron studies may be performed when clinically indicated to assess the effects of chronic blood loss.
    • Reproductive and Fertility Assessment: For patients who are planning pregnancy or experiencing difficulty conceiving, evaluation may include reproductive history and assessment of the uterine cavity and other potential causes of infertility.
    • Assessment for Other Causes of Abnormal Bleeding: Depending on age, symptoms, and clinical findings, doctors may evaluate other causes of abnormal uterine bleeding, including endometrial pathology, adenomyosis, endometriosis, pregnancy-related conditions, or hormonal disorders.
  • Imaging Tests:
    • Transvaginal Ultrasound: Commonly used to identify fibroids and assess their size, number and location within the uterus.
    • Transabdominal Ultrasound: May be useful for evaluating larger fibroids or when a broader view of the pelvis is required.
    • Pelvic MRI: Provides detailed mapping of fibroid size, number and location and may be useful when ultrasound findings are inconclusive or when planning complex surgery or other interventions.
    • Hysteroscopy: May be considered when an intracavitary abnormality is suspected, although intramural fibroids themselves are located within the uterine wall and are primarily assessed through imaging such as ultrasound or MRI.
    • Additional Imaging: Selected patients may require further pelvic imaging depending on symptoms, treatment planning or concern about another pelvic condition.

MediRehab (a chain of Rehab centres, part of MediGence) provides comprehensive tele- rehabilitation services designed to support Intramural Fibroid patients in Singapore. These Services include:

  • Physical Activity and Mobility: Appropriate physical activity can help maintain strength and general well-being. Activity may be temporarily modified after myomectomy or other procedures, based on the surgeon's advice.
  • Pain Management: Patients may receive guidance on safe movement, prescribed pain medicines, and a gradual return to normal activities after treatment.
  • Postoperative Recovery Support: After surgery, rehabilitation focuses on a gradual return to walking, daily activities, work, and exercise while following wound-care and activity restrictions.
  • Medicines for intramural fibroids primarily control symptoms rather than permanently removing the fibroid. Non-steroidal anti-inflammatory drugs (NSAIDs) can help relieve menstrual pain and may reduce bleeding in some patients. Hormonal treatments, including combined hormonal contraceptives, progestogen-based treatments or a levonorgestrel-releasing intrauterine system in appropriate patients, may help manage heavy menstrual bleeding. Other fibroid-directed hormonal medicines may temporarily reduce bleeding and fibroid-related symptoms.

Frequently Asked Questions

Recovery depends on the treatment used. Symptoms managed with medication may improve within days to weeks, while recovery after minimally invasive procedures or myomectomy varies by technique and the extent of surgery. Recovery after open surgery generally takes longer than after laparoscopic or robotic procedures. Your gynecologist can provide an individual recovery timeline.

Yes. Most people with intramural fibroids can walk and remain physically active. However, heavy bleeding, anemia, pelvic pain, pressure or very large fibroids may reduce exercise tolerance. After surgery, doctors usually encourage gradual walking, but you should resume strenuous activity only as advised.

Major Singapore gynecology centres may provide transvaginal and transabdominal ultrasound, pelvic MRI, minimally invasive myomectomy, robotic-assisted surgery, uterine artery embolisation and other fibroid treatment options. The best approach depends on fibroid size, location, symptoms, and reproductive goals.

Some singapore hospitals have international-patient departments that can assist with medical records, specialist consultations, treatment coordination, travel arrangements, accommodation and follow-up care.

Consider a gynecology centre with experience in fibroid management and access to advanced pelvic imaging and multiple treatment options. If preserving fertility or the uterus is important, look for a team experienced in uterus-preserving procedures such as myomectomy and other appropriate minimally invasive approaches.

Outcomes depend on fibroid size, number, location, symptoms, treatment type, and individual health factors. Many patients experience improvement in heavy bleeding, pain and pressure symptoms after appropriate treatment. The treating gynecologist can discuss expected outcomes based on the specific fibroid characteristics.

Gynaecologists at specialised Singapore centres manage symptomatic uterine fibroids using medical, minimally invasive and surgical approaches. Patients with complex fibroids or fertility concerns may benefit from centres with gynecologic surgeons, reproductive specialists, interventional radiologists and advanced imaging facilities.

Risks depend on the treatment selected. Medicines can cause treatment-specific side effects, while myomectomy may involve bleeding, infection, scar formation, or fibroid recurrence. Uterine artery embolisation can cause post-procedure pain, infection or other vascular and reproductive complications in selected patients. Hysterectomy is major surgery and carries surgical and anaesthetic risks. The treating specialist should explain the risks based on the chosen procedure.

Yes. Heavy menstrual bleeding, pelvic pain, pressure, anemia, urinary symptoms and concerns about fertility can affect physical activity, work, social activities, sleep and emotional well-being. Effective treatment can help reduce symptoms and improve daily functioning.

Many intramural fibroids remain stable or asymptomatic and may not require treatment. However, symptomatic or enlarging fibroids can cause persistent heavy menstrual bleeding, iron-deficiency anemia, pelvic pressure, pain, urinary or bowel symptoms and reproductive difficulties. Rarely, acute complications such as degeneration or significant bleeding may occur.

No guaranteed way exists to prevent intramural fibroids because genetic, hormonal, and other factors contribute to their development. Maintaining a healthy weight, following a balanced diet, and addressing metabolic health may support overall health, but these measures cannot completely prevent fibroids. Regular gynecological evaluation is appropriate when symptoms such as heavy menstrual bleeding or pelvic pain develop.

Fibroids commonly develop during the reproductive years and are influenced by genetic, hormonal and other factors. Risk is higher in people with a family history of fibroids and may also be associated with obesity and certain population or genetic factors. Fibroids become less common after menopause, although existing fibroids may persist.
