Intramural Fibroids: What They Are, Symptoms, and Treatment Options

Intramural fibroids are a common type of uterine fibroid that can cause significant discomfort and health issues for women. These fibroids, which develop within the muscular walls of the uterus, can vary in size and impact. If left untreated, they may lead to more severe complications, affecting overall health and fertility. In this article, we’ll explore what intramural fibroids are, their causes, symptoms, and the available treatment options, drawing insights from USA Fibroid Centers.

What Is an Intramural Fibroid?
Intramural fibroids are non-cancerous growths that form within the muscle wall of the uterus. These fibroids are the most common type of uterine fibroid and can range in size from small, pea-sized growths to large, grapefruit-sized masses. Because of their location within the uterine wall, they can distort the shape and size of the uterus, causing a variety of symptoms depending on their size and location.

These fibroids are composed of fibrous tissue and smooth muscle cells. While they are benign, they can still lead to symptoms that disrupt daily life. Intramural fibroids are most commonly diagnosed in women between the ages of 30 and 50 and are often discovered during routine pelvic exams or imaging tests such as ultrasounds or MRIs.

Causes of Intramural Fibroids
The exact cause of intramural fibroids remains unclear, but several factors may contribute to their development. Genetics play a significant role, as women with a family history of fibroids are at an increased risk of developing them. Hormonal changes, particularly an increase in estrogen and progesterone, may also promote the growth of fibroids. These hormones stimulate the growth of fibrous tissue in the uterus, contributing to the formation of fibroids.

Additionally, race and ethnicity can impact the likelihood of developing fibroids. African-American women, for example, are more likely to develop fibroids at an earlier age and experience larger fibroids compared to women of other races. Other factors, such as obesity, vitamin D deficiency, and lifestyle choices, can also influence fibroid development.

Symptoms of Intramural Fibroids
Many women with intramural fibroids may not experience any symptoms, particularly if the fibroids are small. However, when symptoms do occur, they can be quite disruptive. Some of the most common symptoms include:

Heavy Menstrual Bleeding: One of the most common symptoms of intramural fibroids is heavy menstrual bleeding. Women may experience prolonged periods or excessive bleeding that may lead to anemia and fatigue.

Pelvic Pain and Pressure: As fibroids grow, they can exert pressure on the surrounding organs, leading to pelvic pain or a feeling of fullness. This discomfort may worsen during menstruation or sexual intercourse.

Frequent Urination: Large intramural fibroids may press against the bladder, causing frequent urination or difficulty emptying the bladder completely.

Back or Leg Pain: Depending on the size and location of the fibroids, women may also experience pain in the lower back or legs due to pressure on the surrounding nerves.

Reproductive Issues: In some cases, intramural fibroids may impact fertility or increase the risk of miscarriage. Women who are trying to conceive may face challenges due to the fibroids' interference with the uterus.

If you’re experiencing any of these symptoms, it’s essential to consult with a healthcare provider to determine whether fibroids are the underlying cause.

Treatment Options for Intramural Fibroids
While many women with intramural fibroids can manage symptoms with conservative treatments, others may require more advanced interventions. Treatment options for intramural fibroids vary based on factors such as the severity of symptoms, the size of the fibroids, and the woman’s overall health and reproductive plans.

Medications: Medications such as hormonal therapies, including birth control pills or intrauterine devices (IUDs), may help control heavy bleeding and reduce symptoms. Additionally, some medications can shrink the fibroids by blocking the production of hormones that promote their growth.

Uterine Fibroid Embolization (UFE): UFE is a minimally invasive procedure in which a catheter is used to deliver small particles to block blood flow to the fibroids. Without a blood supply, the fibroids shrink and symptoms subside.

Myomectomy: Myomectomy is a surgical procedure that removes fibroids while preserving the uterus. It is typically recommended for women who wish to maintain their fertility.

Hysterectomy: In more severe cases, a hysterectomy, the removal of the uterus, may be necessary. This procedure is often recommended for women who have completed their families or have severe, persistent symptoms.

MRI-guided Focused Ultrasound: This is a non-invasive treatment option that uses high-frequency sound waves to target and destroy fibroids. It’s ideal for women who want to preserve their uterus and avoid surgery.

Conclusion
Intramural fibroids are a common yet often overlooked condition that can cause significant discomfort and disrupt daily life. While many women can manage mild symptoms with medications, others may need more advanced treatments to address the fibroids effectively. If you suspect that you have intramural fibroids or are experiencing symptoms, it’s important to consult with a healthcare provider to discuss your options and create an individualized treatment plan.
