Endometriosis vs fibroids is a common comparison because both can cause pelvic pain, heavy periods, and fertility concerns. Endometriosis happens when tissue similar to the uterine lining grows outside the uterus. Fibroids are noncancerous growths in or around the uterus. The symptoms can overlap, so imaging, a pelvic exam, and sometimes surgery are used to tell the difference.

Pelvic pain can be frustrating because different conditions can feel alike. Heavy bleeding, cramps, pressure, and pain with sex may point to more than one cause.
That is why people often search for endometriosis vs fibroids. They want to know which condition fits their symptoms and what to do next.
At Texas IR, the team treats uterine fibroids with minimally invasive care. Endometriosis is a different condition and is usually managed by a gynecologist. Still, knowing the difference can help you ask better questions at your next visit.
Endometriosis vs Fibroids: The Main Difference
Endometriosis happens when tissue similar to the lining inside the uterus grows outside the uterus. Mayo Clinic notes that endometriosis can cause pelvic pain, especially around menstrual periods [1]. Fibroids are growths made of muscle tissue that grow in the wall of the uterus. The Office on Women’s Health explains that fibroids are almost always benign, meaning not cancerous [2].
So the main difference is location and tissue type. Endometriosis involves lining-like tissue outside the uterus. Fibroids are muscle growths in or around the uterus. Both can cause pain. Both can affect periods. But they are not the same disease.
Endometriosis vs Fibroids Symptoms
Symptoms can overlap, which is why a medical exam matters.
| Symptom or clue | Endometriosis | Fibroids |
| Common pain pattern | Pelvic pain, often worse with periods | Pelvic pressure, cramps, or heavy bleeding |
| Bleeding | May cause heavy or irregular bleeding | Often causes heavy or long periods |
| Pressure | Less likely to feel like a mass | Can cause fullness or belly pressure |
| Bowel or bladder symptoms | Pain with bowel movements or urination may happen during periods | Frequent urination can happen if a fibroid presses on the bladder |
| Fertility | Can make it harder to get pregnant | Can affect fertility depending on size and location |
| Diagnosis | May need laparoscopy to confirm | Often seen on ultrasound or MRI |
Endometriosis vs fibroids symptoms are not always clean-cut. A person with fibroids can have bad cramps. A person with endometriosis can have heavy bleeding. Some people have no symptoms at all.
Can You Have Endometriosis and Fibroids?
Yes, it is possible to have endometriosis and fibroids. Having one does not mean you cannot have the other. This is why symptoms alone are not enough. If you have pelvic pain and heavy bleeding, a doctor may need to check for more than one cause.
It is also why you should not assume that pain is normal just because it happens during your period. Pain that makes you miss work, stay in bed, avoid sex, or plan life around bleeding deserves a real evaluation.
How Doctors Diagnose Fibroids or Endometriosis
Doctors may start with a health history and pelvic exam. They may ask when pain happens, how heavy bleeding is, whether you pass clots, and whether you have bladder or bowel symptoms.
Ultrasound is often used to look for fibroids. MRI may be used when more detail is needed. NICHD lists heavy bleeding, anemia, pelvic pressure, frequent urination, pain during sex, and lower back pain among possible fibroid symptoms [3].
Endometriosis can be harder to confirm. Imaging may help find some related problems, but laparoscopy is often used to confirm endometriosis. Laparoscopy is a surgery where a doctor looks inside the pelvis with a small camera.
If you are unsure whether you have endometriosis or uterine fibroids, ask what tests match your symptoms.
Treatment Options Are Different
Fibroids vs endometriosis matters because treatment is different.
Endometriosis care may include pain medicine, hormone therapy, pelvic floor therapy, or surgery through a gynecology team. The goal is to reduce pain, manage tissue growth, and support fertility goals when needed.
Fibroid care depends on symptoms, fibroid size, location, age, and pregnancy goals. Some people only need monitoring. Others may use medicines, myomectomy, hysterectomy, or uterine fibroid embolization.
Uterine fibroid embolization in Houston and Katy is a minimally invasive treatment for fibroids. It blocks blood flow to fibroids so they shrink over time. UFE does not treat endometriosis.
That distinction matters. If you have both fibroids and endometriosis, your care plan may need more than one type of specialist.
Pelvic Pain Has More Than One Cause: Get Clear Next Steps
If you have been told you have fibroids, or you suspect fibroids are causing heavy bleeding or pressure, Texas IR can help you learn whether UFE may fit your situation.
At Texas IR’s Katy office, Dr. Poyan Rafiei talks with patients about imaging, symptoms, and treatment choices. The goal is to give you clear options without rushing you toward major surgery. You can also view the Google Business Profile for location details.
FAQ
- Which is worse, endometriosis or fibroids? – It depends on the person. Endometriosis can cause severe pain even when imaging looks normal. Fibroids can cause heavy bleeding, anemia, pressure, and fertility concerns.
- Does endometriosis cause fibroids? – No. Endometriosis does not cause fibroids. They are separate conditions, though a person can have both.
- How do I know if I have fibroids or endometriosis? – You need a medical exam. Fibroids are often seen on ultrasound or MRI. Endometriosis may need laparoscopy to confirm.
- Can UFE treat endometriosis? – No. UFE treats uterine fibroids. It does not treat endometriosis.
Conclusion
Endometriosis and fibroids can both disrupt daily life. They can also overlap, which makes self-diagnosis hard.
If your symptoms point to fibroids, schedule a consultation with Texas IR to ask whether UFE may be an option for you. If your symptoms sound more like endometriosis, a gynecologist can guide the right next steps.
