When women think about fibroid symptoms, heavy bleeding and pelvic pain come to mind first. But there’s another set of symptoms that fibroids cause—symptoms that many women never connect to their fibroids at all: bladder problems.
Running to the bathroom every hour. Waking up three or four times a night to urinate. A persistent sensation of bladder pressure even when you’ve just emptied your bladder. Occasional leakage when you cough, sneeze, or laugh.
If this sounds familiar, you’re not alone—and it may not be “just a bladder issue.” Research from the Fibroids and Urinary Symptoms Study (FUSS) found that 56% of women presenting for fibroid treatment reported being at least “somewhat bothered” by frequent urination, 43% reported a sensation of incomplete bladder emptying, and another study found that 60% experienced daytime frequency and 47% experienced nocturia (waking at night to urinate).
Why Fibroids Cause Bladder Symptoms
The uterus sits directly behind and partially on top of the bladder. When fibroids enlarge the uterus, it can compress the bladder and reduce its functional capacity, meaning it can’t hold as much urine before you feel the urge to go.
Fibroid location matters more than size. Anterior fibroids (growing on the front wall of the uterus, facing the bladder) and subserosal fibroids (growing on the outer surface of the uterus) are most likely to cause bladder compression. Even relatively small fibroids in these positions can cause significant urinary symptoms, while larger fibroids in other locations may cause no bladder issues at all.
The specific urinary symptoms fibroids can cause include urinary frequency (needing to urinate more than 6–8 times per day), urinary urgency (a sudden, compelling need to urinate that’s hard to delay), nocturia (waking at night to urinate—often 2–4 times), a sensation of incomplete emptying (feeling like your bladder isn’t fully empty after urinating), stress incontinence (leakage with coughing, sneezing, or physical activity), and in rare cases of very large fibroids, partial urinary obstruction or hydronephrosis (backup of urine affecting the kidneys).
The Diagnostic Disconnect
Many women with fibroid-related bladder symptoms never make the connection. They see a urologist for urinary frequency, receive a diagnosis of overactive bladder, start medication, and wonder why it doesn’t fully help. Or they assume nighttime bathroom trips are a normal part of aging.
The diagnostic gap exists because urinary symptoms have many possible causes—UTIs, diabetes, pelvic floor dysfunction, medications, and age-related changes can all contribute. Unless a provider considers the possibility of fibroids pressing on the bladder, the underlying cause may be missed.
A simple pelvic ultrasound or MRI can reveal whether fibroids are positioned to compress the bladder. If you’re experiencing persistent urinary symptoms and you’re a woman of reproductive age (or perimenopausal), it’s worth asking your doctor whether fibroids could be contributing.
How UFE Addresses Bladder Symptoms
Uterine fibroid embolization shrinks fibroids by blocking their blood supply. As the fibroids reduce in size over the weeks and months following the procedure, the pressure they exert on surrounding structures, including the bladder, decreases proportionally.
The published evidence on this is encouraging. A clinical study of women with large fibroids and urinary symptoms found that after treatment-induced fibroid shrinkage (average 55% volume reduction), daytime urinary frequency resolved in 11 of 12 patients, urgency decreased in 11 of 13, and nocturia improved in 8 of 10.
The UFE recovery timeline for bladder symptom improvement follows the fibroid shrinkage timeline: initial improvement may be noticed within weeks, but the full benefit typically develops over three to six months as the fibroids continue to shrink.
When to Talk to Your Doctor
Consider scheduling a fibroid evaluation if you have urinary frequency or urgency that doesn’t fully respond to standard treatments, nocturia that disrupts your sleep—especially if it started or worsened alongside other pelvic symptoms, you’re also experiencing heavy menstrual bleeding, pelvic pressure, or bloating, or you have a known fibroid diagnosis and haven’t discussed your bladder symptoms with your provider.
At SACMD, Dr. Albert Chun evaluates the complete picture of your fibroid-related symptoms—not just bleeding but pressure, bladder function, and quality of life—when determining whether UFE is the right treatment.

The Bottom Line
Bladder symptoms are among the most underrecognized consequences of uterine fibroids. If you’ve been told you have “overactive bladder” but also have fibroids or pelvic pressure, the two may be directly connected. UFE can shrink the fibroids causing bladder compression and restore normal urinary function—without surgery and without removing your uterus.
