Endo After Menopause and Fibroids: What to Know

Endo After Menopause and Fibroids: What to Know

Pelvic pain or bleeding after menopause can be unsettling—especially if you’ve lived with endometriosis (often called “endo”) or uterine fibroids in the past. While both conditions are usually driven by estrogen and are most active before menopause, they can still affect people after periods stop. Here’s what to know, what to watch for, and how today’s evidence-based care can help.

Quick overview

  • Endometriosis after menopause is uncommon but possible. Symptoms can persist or recur, especially with hormone therapy or residual lesions.
  • Fibroids typically shrink after menopause, but some remain symptomatic. Any new or recurrent bleeding after menopause should be evaluated.
  • Evaluation matters. Postmenopausal bleeding and new pelvic pain warrant timely medical assessment to rule out other causes.
  • Treatment is personalized. Options range from watchful waiting and pain control to targeted procedures. Hormone therapy (HT) choices may need adjustment if you have a history of endometriosis or fibroids.

Can endometriosis persist or appear after menopause?

Endometriosis happens when tissue similar to the uterine lining grows outside the uterus, causing inflammation and pain. Although classically a condition of reproductive years, the U.S. Office on Women’s Health notes that endometriosis can occur—even if rarely—after menopause. Why? A few reasons:

  • Residual or persistent lesions can remain active at low estrogen levels.
  • Exogenous estrogen from menopausal hormone therapy can stimulate lesions in susceptible individuals.
  • Peripheral estrogen production in adipose tissue via aromatase may provide enough hormone signaling to maintain symptoms in some people.

Postmenopausal endometriosis may present as chronic pelvic pain, pain with intercourse, or, less commonly, bleeding if lesions involve the vagina or surgical scars. Because symptoms can overlap with other conditions—including pelvic floor disorders, gastrointestinal issues, and, rarely, malignancies—evaluation is important.

For general background on endometriosis, see NIH MedlinePlus: Endometriosis.

What happens to fibroids after menopause?

Uterine fibroids (leiomyomas) are benign muscle tumors of the uterus. They are extremely common before menopause and often shrink afterward as estrogen and progesterone levels fall. Still, some fibroids remain large enough to cause pressure symptoms (pelvic fullness, urinary frequency, constipation), or they may calcify and remain firm. Helpful primers are available from NIH MedlinePlus and the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).

Important caveat: any vaginal bleeding after menopause is not considered normal and should be evaluated. Bleeding can have benign causes (such as thinning of the vaginal tissue), but it can also signal endometrial pathology. The National Cancer Institute notes that unusual postmenopausal bleeding is a common symptom of endometrial cancer and warrants prompt assessment (NCI PDQ, patient version).

Symptoms to watch—and when to call your doctor

  • Vaginal bleeding or spotting after menopause (even once)
  • New or worsening pelvic pain or pressure
  • Rapidly enlarging abdominal/pelvic mass or increasing girth
  • Pain with intercourse, changes in bowel or bladder habits, or persistent bloating
  • Unintended weight loss, fatigue, or anemia symptoms (e.g., shortness of breath)

These signs don’t necessarily mean something serious is wrong, but they deserve evaluation.

How clinicians evaluate pelvic pain or bleeding after menopause

Your clinician will review your history, prior surgeries, and medication use (including hormone therapy), then tailor testing. Common steps include:

  • Pelvic exam to identify tenderness, masses, or lesions.
  • Transvaginal ultrasound to assess the uterus, lining thickness, and any fibroids or ovarian cysts.
  • Endometrial sampling (biopsy) if postmenopausal bleeding is present.
  • MRI for complex cases or when ultrasound is inconclusive.
  • Laparoscopy is less commonly needed in postmenopause but may be used if endometriosis or other pathology is suspected and imaging is non-diagnostic.

Blood tests (for example, CA-125) are nonspecific and not diagnostic but may be used alongside imaging in select scenarios.

Treatment options tailored to postmenopause

Medication and non-surgical approaches

  • Watchful waiting can be appropriate for mild symptoms, especially if imaging is reassuring and there is no bleeding.
  • Pain control with NSAIDs or acetaminophen for intermittent discomfort.
  • Hormone adjustments if you are using menopausal hormone therapy (HT). In those with prior endometriosis, clinicians may prefer the lowest effective estrogen dose, often combined with a progestin to reduce stimulation of residual endometrial-like tissue. The Office on Women’s Health outlines HT options and risks (OWH: Menopause Hormone Therapy).
  • Other medications sometimes used premenopausally (e.g., GnRH analogs or antagonists) are less commonly indicated after menopause. Some therapies approved by the FDA for fibroid-related heavy menstrual bleeding are indicated for premenopausal patients, not for those already postmenopausal.

Procedures and surgery

  • Hysteroscopy (to evaluate and treat polyps or submucosal fibroids) may be used when postmenopausal bleeding is present and structural causes are suspected.
  • Uterine-sparing procedures such as uterine artery embolization are generally considered when cancer has been excluded; decisions are individualized based on symptoms and risk profile.
  • Surgery (myomectomy or hysterectomy) may be recommended for persistent symptoms, large masses, or concerning features. If surgery is planned, your team will choose techniques that minimize risks. The U.S. Food and Drug Administration cautions against using laparoscopic power morcellators in patients who are postmenopausal or over 50 due to the risk of unintentionally spreading an undiagnosed uterine cancer; if morcellation is considered, FDA recommends contained techniques and careful patient selection (FDA Safety Communication).

Hormone therapy tips if you have a history of endometriosis or fibroids

  • Discuss risks and benefits of HT in detail, particularly if you had severe endometriosis or large fibroids premenopausally.
  • Use the lowest effective dose for the shortest duration that controls menopausal symptoms, and consider combined regimens (estrogen with progestin) when appropriate.
  • Monitor for recurrence of pelvic pain or bleeding; report any new symptoms promptly.

Lifestyle and self-advocacy

  • Healthy weight may reduce peripheral estrogen production and lower symptom triggers.
  • Regular physical activity supports pelvic and overall health.
  • Pelvic floor physical therapy can help address pain related to muscle tension and improve quality of life.
  • Track symptoms and share a concise history (prior diagnoses, procedures, and medications) with your clinician to streamline care.

Key takeaways

  • Endometriosis after menopause is uncommon but real; fibroids usually shrink, yet both conditions can still cause symptoms.
  • Any bleeding after menopause requires evaluation. Don’t wait—early assessment clarifies the cause and guides safe treatment.
  • Therapy is individualized: from watchful waiting to targeted procedures, with special consideration of hormone use and surgical techniques in postmenopause.
