For many women, the path to relief from fibroids no longer requires major surgery. Uterine fibroid embolization (UFE) has emerged as a modern, minimally invasive alternative to hysterectomy and myomectomy, offering a shorter recovery without a hospital stay.
While UFE is celebrated for its high success rate and quick recovery, patients need to have a clear picture of what to expect during the healing process. Like any medical procedure, uterine fibroid embolization side effects occur as the body reacts to the treatment and the fibroids begin to shrink. Understanding these UFE side effects allows you to approach your recovery with confidence rather than concern.
Understanding UFE Side Effects
Experiencing uterine fibroid embolization side effects after treatment is not a sign that something is wrong; rather, it is a natural part of the healing process. As the blood supply to the fibroids is blocked, the fibroid tissue begins to break down, triggering a response from your immune system as it works to absorb the treated tissue.
The Short-Term Side Effects of Uterine Fibroid Embolization
The majority of UFE side effects are short-term and occur within the first few days following the procedure. These are generally manageable with rest and the medications prescribed by your specialist.
- Pelvic Cramping: This is the most common side effect. As the fibroids lose their blood supply, you may experience cramping that feels like a heavy period. This is usually most intense in the first 24 hours.
- Low-Grade Fever and Fatigue: Your body’s inflammatory response to the treated fibroid tissue can cause a mild fever (usually under 101°F) and a general feeling of tiredness.
- Nausea: Some patients experience mild nausea on the first day, often due to sedation used during the procedure or the body’s response to the embolization.
- Spotting or Vaginal Discharge: It is normal to experience some vaginal discharge or spotting for a few weeks as the treated tissue is processed by the body.
- Post-Embolization Syndrome (PES): This is a collective term for the flu-like symptoms (fatigue, mild fever, nausea, and cramping) that many women experience in the first week after an embolization. While uncomfortable, it is a sign that the treatment is working.
The Long-Term Side Effects of Fibroid Embolization
When considering the long-term side effects of fibroid embolization, it is helpful to distinguish between temporary physiological shifts and the overwhelmingly positive lifestyle changes most women report.
1. Fertility and Pregnancy
UFE is a uterus-preserving treatment. Unlike a hysterectomy, which completely removes the possibility of pregnancy, UFE leaves the uterus intact. This makes it a vital option for women who wish to avoid major surgery.
The Ovarian Reserve Factor: A potential consideration is a temporary or, in rare cases, permanent decrease in ovarian function. Since the blood supply to the ovaries can sometimes be connected to the uterine arteries, a small amount of the embolic material can reach the ovaries. For most women, this does not impact their long-term health, but it is a factor to discuss if you are planning a future pregnancy. Generally, UFE is considered much less invasive to the reproductive system than surgical alternatives and does not influence fertility.
Pregnancy Outcomes: Many women have gone on to have healthy, successful pregnancies after UFE. However, clinical studies have noted a few specific considerations regarding pregnancy outcomes, such as potential risks for placenta attachment, malpresentation, increased C-section rates, or preterm birth. If pregnancy is a primary goal, your specialist will help you weigh these factors.
2. Positive Menstrual Changes
The primary long-term side effect of UFE that most women hope for is the reduction of heavy, painful bleeding. Most women see their periods become significantly lighter and more manageable within a few cycles. In some cases, periods may stop temporarily before returning to a new, healthier “normal.”
3. Recurrence of Fibroids vs. Regrowth
UFE is highly effective because it treats all existing fibroids simultaneously. However, UFE does not change your genetic predisposition to fibroids. While it is rare, new fibroids can grow years later for some women. This happens in a much smaller percentage of patients compared to those who undergo a myomectomy (surgical removal of individual fibroids), where small, hidden fibroids are often left behind.
4. Improved Sexual and Pelvic Health
In the long run, UFE is often transformative for sexual health. Large fibroids frequently make intercourse painful (dyspareunia) and cause constant pelvic pressure. As the fibroids shrink over the months following UFE, patients typically report a restoration of sexual comfort and the disappearance of that “heavy” feeling in the pelvis.
5. Early Menopause
One of the rare negative long-term side effects of fibroid embolization (roughly 1–5% risk) is early menopause. This is most common in women over the age of 45. For a woman already near the age of menopause, UFE might “nudge” the body into it a year or two early. For younger women, this is an exceptionally rare complication.
UFE Side Effects vs. Surgery: A Comparison
| Feature | UFE Side Effects/Recovery | Surgical Side Effects/Recovery |
| Recovery Time | 1–2 weeks | 6–8 weeks |
| Hospital Stay | Outpatient (Home same day) | 2–3 days in hospital |
| Anesthesia | Local/Moderate Sedation | General Anesthesia |
| Physical Impact | No scarring; uterus is preserved | Visible scars; potential uterine removal |
How Long Do UFE Side Effects Last?
Recovery isn’t an overnight event, but it is a predictable one. Here is a general timeline of what most patients experience:
- First 24 Hours: Most intense cramping and nausea. This is the time for absolute rest and prescribed pain management.
- First Week: Post-Embolization Syndrome (PES) may set in. You may feel tired and have a mild fever. Most women return to light activity by day 5 or 7.
- First Month: Energy levels return to normal. You may experience your first post-procedure period, which could still be heavy or slightly irregular.
- 3–6 Months: This is the “golden window” where the most significant fibroid shrinkage occurs. Symptoms like pelvic pressure and urinary frequency typically resolve during this time.
Fibroid Recurrence vs UFE Side Effects
It is important to differentiate between symptom recurrence (the return of heavy bleeding) and side effects of the UFE procedure. If symptoms return after several years, it usually indicates the growth of new fibroids rather than the failure of the initial treatment. It is recommended to follow up with imaging (usually an ultrasound or MRI) at 6 and 12 months to monitor the shrinkage of the treated fibroids.
Why Are There UFE Side Effects?
The presence of uterine fibroid embolization side effects, such as post-embolization syndrome, actually provides biological confirmation that the procedure was successful. By injecting embolic material into the uterine arteries, the fibroid specialist cuts off the oxygen and nutrients the fibroids need to survive. Your body goes through a biological “cleanup” process as those fibroids begin to shrink and break down.
The most common cause of side effects is a temporary condition called post-embolization syndrome. As the treated fibroid tissue loses its oxygen supply, the body triggers a natural inflammatory response. This often feels like a mild case of the flu and can include:
- Pelvic cramping and discomfort
- Nausea or a low-grade fever
- General fatigue or “malaise”
While these symptoms can be intense for the first 24 to 48 hours, they are typically self-limiting and resolve within a week. Not everyone experiences the UFE side effects the same way. Your recovery experience can vary based on:
- Fibroid Size and Number: Larger fibroids or a higher “fibroid load” may lead to a more pronounced inflammatory response.
- Individual Health: Factors like your overall immune health and pain tolerance play a role.
- Medical History: Pre-existing conditions, such as obesity or previous pelvic surgeries, can slightly alter the risk profile.
Compared with surgical options such as a hysterectomy or myomectomy, the side effects of UFE are generally less severe, shorter in duration, and carry fewer risks and complications. Since UFE avoids large incisions and general anesthesia, you bypass the risks of significant blood loss, surgical site infections, and the long, painful healing process associated with cutting through muscle and tissue.
Who’s Most at Risk of Experiencing UFE Side Effects?
Even though UFE is safe for most women, certain factors can influence the intensity of the uterine fibroid embolization side effects. Identifying these risks early allows your medical team to tailor your recovery plan.
Key Risk Factors
- Pre-existing Anemia: If heavy periods have already left you with low iron levels, you may feel more significant fatigue during recovery. Since the body uses extra energy to heal and process the treated tissue, managing anemia before the procedure can help mitigate post-op exhaustion.
- Large Fibroids: Generally, a fibroid is considered large if it exceeds 10 cm in diameter (roughly the size of a grapefruit). Treating large fibroids can result in a more pronounced inflammatory response—known as post-embolization syndrome—simply because there is more tissue for the body to break down.
- Perimenopause: Women in their late 40s or early 50s may have a slightly higher risk of experiencing permanent changes to their menstrual cycle or earlier onset of menopause following UFE, as the ovaries and uterus are already transitioning.
- Previous Pelvic Surgery: A history of surgeries (like a C-section or myomectomy) can sometimes result in scar tissue or altered blood flow patterns. While this doesn’t prevent you from having UFE, it is an important factor for your specialist to review to minimize UFE side effects.
Identifying these factors early can help choose the right treatment option and better manage UFE side effects.
Managing Potential Side Effects of the UFE Procedure
Managing uterine fibroid embolization side effects is straightforward with the right information and preparation.
At-Home Care Tips
- Hydrate: Drink plenty of water to help your kidneys flush the contrast dye used during the procedure.
- Heat Therapy: A heating pad on the lower abdomen can work wonders for post-procedure cramping.
- Gradual Activity: While you should rest for the first few days, gentle walking around the house can help prevent blood clots and boost circulation.
When to Contact Your Doctor
While most side effects are normal, you should call your specialist if you experience:
- A fever higher than 101.5°F.
- Pain that is not controlled by your prescribed medication.
- Foul-smelling vaginal discharge.
- Heavy bleeding that requires changing a pad every hour.

Frequently Asked Questions
Is post-embolization syndrome (PES) dangerous?
Post-embolization syndrome (PES) is typically not dangerous. PES is a normal, expected inflammatory response. While it feels like a mild flu, it is not an infection and typically resolves within a week.
Can uterine fibroid embolization side effects be prevented?
Uterine fibroid embolization side effects cannot be prevented in terms of stopping the body’s natural healing response. However, symptoms can be effectively managed with medications (like anti-inflammatories and anti-nausea medications) prescribed by your doctor before the procedure begins.
Does UFE affect your arteries?
Uterine fibroid embolization (UFE) does not affect your arteries overall. The procedure specifically targets only the uterine arteries supplying the fibroids. Since the catheter is very thin and the embolic material is biocompatible, your overall arterial health and circulation to the rest of your body remain unaffected.
