The Types of Uterine Fibroids

If you have been diagnosed with uterine fibroids, you may be interested to learn that there are several different types. Fibroids are generally classified by location and can vary in size and number. Although not everyone experiences fibroid symptoms, the location, size, and number of fibroids involved tend to impact their severity.

For expert care, we recommend consulting a fibroid specialist. At USA Fibroid Centers, our doctors specialize in using medical imaging tools like ultrasounds and magnetic resonance imaging (MRIs) to provide an accurate diagnosis of your fibroids. If you’ve been diagnosed with fibroids, we perform a non-surgical treatment, Uterine Fibroid Embolization (UFE), that allows you to get back to your normal routine sooner and can alleviate symptoms.

How Many Types of Fibroids Are There?

There are several different types of uterine fibroids. Below, we provide a brief overview of the five main kinds of fibroids.

5 Different Types of Fibroids

1. Intramural Fibroids 

An intramural fibroid grows within the muscular walls of the uterus. If you have small intramural fibroids, you may experience only mild symptoms. As the fibroids grow larger, you may develop more severe symptoms that can eventually impact your quality of life.

Common symptoms of intramural fibroids include:

  • Heavy periods that last 10 days or more
  • Irregular bleeding between periods
  • Pelvic or lower back pain

2. Subserosal Fibroids 

A subserosal fibroid grows on the outside of the uterus, bulging into the pelvic or abdominal cavity. It can be attached to the uterus directly or via a thin stalk called a peduncle. As with other types of fibroids, subserosal fibroids can vary in size and number.

Subserosal fibroid symptoms tend to be somewhat different from those of intramural fibroids. For instance, women often experience fewer issues with their uterus and more symptoms involving neighboring organs like the bladder, rectum, or intestines.

Common symptoms of subserosal fibroids include:

  • A feeling of heaviness or fullness within the pelvic region
  • Frequent urination
  • Constipation or bloating
  • Abdominal pain and cramping

Depending on their size and location, subserosal fibroids can sometimes lead to an expanded uterus. Consequently, this may cause your abdominal region to extend and mimic the look of pregnant body. If you have taken a pregnancy test and it has come back negative or inconclusive, consult your doctor to see if you could have uterine fibroids.

3. Submucosal Fibroids

A submucosal fibroid develops within the innermost lining of the uterus, or endometrium. Submucosal fibroids can develop individually or in clusters and vary in size. This type of fibroid is the one most likely to cause heavy menstrual bleeding.

Common symptoms of submucosal fibroids include:

  • Heavy or prolonged menstruation 
  • Bleeding between periods
  • Anemia, fatigue, or dizziness
  • Pelvic or lower back pain
  • Passing frequent or large blood clots (bigger than a quarter)

4. Pedunculated Fibroids

A pedunculated fibroid is a type of fibroid that is attached to the uterine wall by a stalk, or peduncle. There are two subtypes, based on location: 

  • Pedunculated subserosal fibroids: Develop outside the uterus
  • Pedunculated submucosal fibroids: Develop inside the uterus

Pedunculated fibroids may cause sharp stabbing pains when the fibroid rotates on the peduncle, interfering with the blood flow to the fibroid.

5. Calcified Fibroids

A calcified uterine fibroid has outgrown its blood supply. When this occurs, you may experience a painful process called fibroid degeneration during which a portion of the fibroid dies. Calcium deposits can then develop on top of the remaining fibroid tissue causing it to become hardened. 

Although calcification usually occurs after menopause, it can also happen during the reproductive years of a woman’s life. Calcified fibroids can sometimes result in new or increased symptoms, including:

  • Frequent urination
  • Constipation
  • Severe abdominal pain or pressure

What Are The Differences Between All The Types of Fibroids?

Even with this information, understanding how the types of uterine fibroids relate to your symptoms can be confusing and stressful. The best way to know what type your fibroids are is to get a pelvic exam, ultrasound, or MRI from a fibroid specialist. 

We want our patients to be informed so they can make the best decisions for their health. Use this chart to guide your understanding of fibroids and types of fibroid symptoms.

Uterine Fibroid Treatment Options

Uterine fibroids can severely impact your quality of life with symptoms like heavy bleeding and frequent urination which can make it hard to manage daily routines and impact your social life or relationships. Fortunately, non-surgical treatment is available that can alleviate painful symptoms and quickly get you back to living your life. 

Many people believe that surgery, either a myomectomy or a hysterectomy, is the only treatment for fibroids. However, both procedures require an extended recovery period, and can have serious or long-term side effects. 

Myomectomy: This surgical procedure removes the fibroids through an incision. However, this option can cause infection of the uterus, fallopian tubes, or ovaries. A myomectomy leaves scar tissue, and, in some cases, scar tissue can cause infertility. You will need stitches, a hospital stay of 1-4 days, and a recovery period of up to 6 weeks. 

Hysterectomy: This surgery removes the uterus along with the fibroids, permanently ending menstruation and the ability to have children. Sometimes, other organs are also removed. Because you won’t get your period anymore, your body will go into menopause and you may have to take hormone-replacement therapy. Additionally, a hysterectomy requires a hospital stay of about 2-3 days and a recovery period of up to eight weeks. 

Uterine Fibroid Embolization (UFE): A non-surgical treatment that involves inserting a catheter to deliver embolic agents to the artery feeding the fibroids, causing them to shrink and eventually die. It is an outpatient procedure, which means you can go home the same day without scars or stitches. There are many benefits to UFE, including a short recovery time of about one week and preservation of fertility. Many patients also experience less pain and lighter periods after having a UFE.
