What Is Fibroid Sloughing? Causes, Symptoms & Treatment
Author : USA Fibroid Center | Published On : 21 Aug 2026
Fibroid sloughing refers to the process in which fibroid tissue breaks down and may eventually pass through the cervix and vagina. It can occur when a uterine fibroid loses a significant portion of its blood supply, causing the tissue to degenerate. Fibroid sloughing is sometimes seen after treatments that reduce blood flow to fibroids, such as uterine fibroid embolization (UFE).
Understanding fibroid sloughing can help patients recognize possible changes during recovery and understand when symptoms should be discussed with a healthcare professional. The experience can vary depending on the fibroid's size, location, blood supply, and the treatment performed.
What Is Fibroid Sloughing?
Fibroid sloughing occurs when a fibroid or part of a degenerating fibroid separates from the uterine wall and passes through the cervix. The process can involve vaginal bleeding, discharge, cramping, or the passage of tissue.
Fibroids are noncancerous growths made primarily of smooth muscle and connective tissue. They develop in or around the uterus and can range from very small growths to larger masses. Some fibroids cause no symptoms, while others may contribute to heavy menstrual bleeding, pelvic pressure, abdominal pain, frequent urination, or reproductive concerns.
Not every person with fibroids experiences sloughing. It is more likely to occur when a fibroid is located close to the uterine cavity and undergoes significant degeneration.
What Causes Fibroid Sloughing?
The primary process behind fibroid sloughing is a reduction in blood supply to the fibroid. Fibroids require blood flow to receive oxygen and nutrients. When blood flow decreases substantially, the fibroid tissue can begin to break down.
One situation in which this may happen is after uterine fibroid embolization. During UFE, small particles are delivered through the arteries supplying the fibroid. These particles reduce blood flow, causing the fibroid to shrink and undergo degeneration.
In some cases, the degenerating fibroid can gradually separate from the uterine wall and pass through the cervix. This is known as sloughing.
Fibroid sloughing can also occur in certain fibroids that naturally undergo degeneration. However, vaginal tissue passage does not always mean that a fibroid is being expelled. Blood clots, uterine lining, and other material can have a similar appearance.
Fibroid Sloughing After UFE
UFE is a minimally invasive treatment for symptomatic uterine fibroids. Rather than surgically removing the uterus or individual fibroids, the procedure works by reducing blood flow to the fibroids.
After UFE, the treated fibroid begins to undergo changes. As its blood supply decreases, the tissue can degenerate and shrink. Depending on its location, a fibroid may eventually be expelled through the cervix.
Not everyone undergoing UFE will experience fibroid sloughing. Many patients experience fibroid shrinkage without passing visible tissue.
Recovery also varies from person to person. Your healthcare provider can explain what symptoms are expected after treatment and what signs may require additional evaluation.
What Are the Symptoms of Fibroid Sloughing?
The symptoms of fibroid sloughing can vary. Some people may experience noticeable tissue passage, while others may have only mild spotting or discharge.
Possible symptoms include:
- Vaginal bleeding or spotting
- Passing tissue through the vagina
- Pelvic cramping
- Lower abdominal discomfort
- Increased vaginal discharge
- Pelvic pressure
- Changes in menstrual bleeding
- Unusual or unpleasant-smelling discharge
The amount of bleeding can also vary. Some spotting may occur during the process, while heavier bleeding should be discussed with a healthcare professional.
If you notice tissue coming from the vagina after fibroid treatment, do not assume that it is definitely fibroid tissue. Your healthcare provider can help determine what the material may be.
What Does Sloughed Fibroid Tissue Look Like?
There is no single appearance associated with fibroid sloughing. Passed material may appear gray, white, pink, red, brown, or tan. It can be soft, firm, irregular, or mixed with blood and vaginal discharge.
The appearance may depend on how extensively the fibroid has degenerated. A fibroid that has undergone extensive tissue breakdown may look different from a piece of tissue that has separated more recently.
Because blood clots and uterine tissue can sometimes resemble fibroid material, visual appearance alone cannot reliably confirm that a fibroid has been expelled.
If you are concerned about tissue you have passed, contact your healthcare provider. If your provider recommends saving the tissue for examination, follow their instructions.
Fibroid Sloughing vs. Fibroid Degeneration
Although the terms are related, fibroid degeneration and fibroid sloughing are not exactly the same.
Fibroid degeneration occurs when the fibroid's blood supply becomes inadequate, causing changes or breakdown within the fibroid. Several forms of degeneration can occur.
Fibroid sloughing refers more specifically to the process of tissue separating and being passed, usually through the cervix and vagina.
Therefore, a fibroid can undergo degeneration without being sloughed from the uterus. Many treated fibroids simply shrink within the uterus over time.
How Long Does Fibroid Sloughing Last?
There is no standard timeline for fibroid sloughing. The duration can depend on the size and location of the fibroid, the degree of degeneration, the amount of blood supply remaining, and the treatment used.
Some patients may notice tissue passage during recovery, while others may experience intermittent discharge or spotting over a longer period.
Following your healthcare provider's post-treatment instructions is important. Your provider may recommend follow-up imaging or appointments to evaluate how the fibroid is responding to treatment.
Is Fibroid Sloughing Normal?
When fibroid sloughing occurs as an expected part of treatment or fibroid degeneration, it may not indicate a problem. However, symptoms should still be monitored carefully.
Some cramping, spotting, or vaginal discharge can occur during recovery from certain fibroid treatments. The specific symptoms considered normal depend on the procedure and individual circumstances.
Patients should not attempt to remove fibroid tissue themselves or insert anything into the vagina to speed up the process. Allow the body to pass tissue naturally and follow the instructions provided by your healthcare team.
When Should You Contact a Doctor?
Although some symptoms can occur during fibroid degeneration and recovery, certain changes require medical attention.
Contact your healthcare provider if you experience:
- Heavy or persistent vaginal bleeding
- Severe or worsening pelvic pain
- Fever or chills
- Foul-smelling vaginal discharge
- Increasing weakness or dizziness
- Fainting
- Persistent vomiting
- Symptoms that suddenly worsen
These symptoms can sometimes indicate complications such as infection or significant blood loss.
If bleeding is severe or you experience fainting, severe pain, or other emergency symptoms, seek urgent medical care.
How Is Fibroid Sloughing Treated?
Fibroid sloughing itself may not require a separate treatment if the tissue is passing naturally and the patient is recovering appropriately. Treatment depends on the underlying cause and the symptoms involved.
A healthcare provider may monitor the patient's condition, perform a pelvic examination, or use imaging to evaluate the uterus and remaining fibroid tissue.
If infection or another complication develops, additional treatment may be necessary. The appropriate approach depends on the patient's symptoms and medical findings.
Patients should avoid attempting to manually remove tissue. Medical evaluation is the safest way to determine whether tissue passage is part of normal fibroid degeneration or requires intervention.
Treatments That Can Cause Fibroid Degeneration
Several fibroid treatments work by reducing, destroying, or removing fibroid tissue. UFE is one minimally invasive option that reduces blood flow to fibroids.
Other treatment options may include medication, fibroid ablation, myomectomy, or hysterectomy. The most appropriate option depends on factors such as fibroid size, location, number, symptoms, overall health, and future pregnancy plans.
A healthcare professional can explain the benefits, risks, and expected recovery associated with each treatment.
Can Fibroid Sloughing Affect Fertility?
Fibroids themselves can sometimes affect fertility depending on their size and location. Fibroids that distort the uterine cavity may have a greater potential to interfere with reproductive outcomes.
Whether fibroid sloughing or a particular fibroid treatment affects fertility depends on individual circumstances. Anyone who hopes to become pregnant should discuss fertility goals with a qualified healthcare provider before choosing a treatment.
What to Expect During Recovery
Recovery after fibroid treatment varies. Patients may experience temporary pelvic cramping, fatigue, spotting, vaginal discharge, or changes in menstrual bleeding.
If fibroid tissue begins to pass, the experience may be unfamiliar or concerning. Staying in communication with your healthcare team can help you understand whether your symptoms are expected.
Follow-up appointments are important because they allow your provider to evaluate your recovery and determine whether the treatment is working as intended.
Final Thoughts
Fibroid sloughing is the passage of fibroid or degenerating fibroid tissue through the cervix and vagina. It can occur when a fibroid loses its blood supply and undergoes significant degeneration, including after treatments such as uterine fibroid embolization.
Possible symptoms include spotting, vaginal bleeding, pelvic cramping, discharge, and passage of tissue. The appearance and duration of sloughing can vary considerably, and not every patient will experience it.
While fibroid sloughing may be part of the treatment or degeneration process, heavy bleeding, severe pain, fever, chills, or foul-smelling discharge should not be ignored. If you have concerns about symptoms or tissue passage, consult your healthcare provider for personalized guidance.
