Yes, fibroids can make you urinate more often. The bladder sits just in front of the uterus. When fibroids enlarge the uterus, or grow in a spot close to the bladder, they can press on it and leave less room for urine. You may feel you need to go often, feel sudden urgency, or find it hard to empty your bladder fully. Doctors call these "bulk" or "pressure" symptoms, because they come from the size and position of the fibroids rather than from bleeding.
Why fibroids press on the bladder
Fibroids are noncancerous growths of the uterine muscle. Many are small and cause no trouble. Others grow large enough to change the size and shape of the uterus. A 2025 evidence review in American Family Physician lists urinary frequency or urgency among the symptoms "associated with increased uterine size," along with a swollen abdomen and constipation.
Size is not the whole story. An earlier American Family Physician review explains that symptoms depend on "the size, number, and location" of the fibroids. A fairly small fibroid in the wrong place can bother the bladder, while a larger one pointing another way may not. Our guide to types of fibroids explains how location is described.
Aetna's medical policy for fibroid treatment describes the mechanism plainly: urinary symptoms from compression of the bladder or the ureter, the tube that carries urine from each kidney to the bladder.
What fibroid-related bladder symptoms feel like
Pressure symptoms usually build gradually, so many women adjust without noticing how much their routine has changed. Common descriptions include:
- Needing to urinate more often than you used to, day or night
- A sudden, strong urge to go
- Leaking because you cannot get to the bathroom in time
- Feeling that your bladder never fully empties, or a slow stream
- A heavy, full feeling low in the pelvis
- Constipation or pressure on the rectum, which often comes with bladder symptoms
ACOG's patient guide lists "difficulty urinating or frequent urination" as fibroid symptoms. The UK's NHS describes it as "peeing more often than usual, needing to pee suddenly or not being able to control when you pee." Pressure symptoms often show up alongside a visibly larger lower belly.
Fibroids are only one possible cause
Frequent urination is common, and fibroids are far from the only reason for it. MedlinePlus, the National Library of Medicine's health site, lists many causes, including:
- Urinary tract infection
- Vaginal infection or irritation
- Caffeine or alcohol
- Pregnancy
- Diabetes that is not well controlled
- Overactive bladder
- Interstitial cystitis (a painful bladder condition)
- Water pills (diuretics)
- Anxiety
- Nerve or spine problems
- A "tumor or growth in the pelvis," which includes fibroids
More than one cause can be at work. You can have fibroids and an overactive bladder, for example. That is why the first step is a proper check-up, not an assumption. Treating fibroids will not help symptoms that come from something else.
Ovarian problems can also cause urinary changes. The CDC lists a "more frequent or urgent need to urinate" among possible signs of ovarian cancer, together with bloating, pelvic pressure and feeling full quickly. The CDC advises seeing a doctor if any of these signs last 2 weeks or longer and are not normal for you. Most of the time the cause is not cancer, but it is a good reason not to put off an exam.

When to get care quickly
| What you notice | What to do |
|---|---|
| You cannot pass urine at all, or only a trickle with a painfully full bladder | Seek urgent care the same day. Fibroids can rarely cause acute urinary retention. |
| Fever, back or side pain, vomiting, or shaking chills | Contact a doctor right away (MedlinePlus). |
| Increased thirst or appetite, fatigue, or sudden weight loss | Contact a doctor right away (MedlinePlus). |
| Blood in the urine, or cloudy urine | Book a prompt appointment. |
| Frequency or urgency that has crept up over months, with heavy periods or pelvic fullness | Arrange a routine visit to check for fibroids and other causes. |
A 2009 review of acute fibroid complications lists acute urinary retention and kidney failure among the rare emergencies fibroids can cause. These are uncommon, but they explain why a bladder that will not empty should never be ignored.
How the cause is found
According to the 2025 American Family Physician review, a fibroid evaluation starts with your history and an abdominal and pelvic exam. Your doctor may also want to rule out infection or other bladder problems. The usual first imaging test is pelvic ultrasound, done through the abdomen and through the vagina. MRI with contrast may be used to map the fibroids in more detail and plan treatment. MRI is especially useful before procedures such as embolization, because it shows the size, number, position and blood supply of each fibroid. Read more in ultrasound vs MRI for fibroids.
Treatment options for pressure symptoms
Bulk symptoms respond differently from bleeding. The 2025 review notes that medicines are mainly used to control heavy or irregular bleeding. Procedures are what reduce bulk symptoms. Those include hysterectomy, myomectomy, uterine artery embolization, radiofrequency ablation and focused ultrasound. Which one fits depends on fibroid size and location, whether you want to keep your uterus, and your pregnancy plans.
- Myomectomy removes the fibroids, including the one pressing on the bladder, and keeps the uterus. ACOG notes that fibroids can come back afterward.
- Hysterectomy removes the uterus and the fibroids with it. It is the definitive option for women who do not want future pregnancy.
- Uterine fibroid embolization (UFE) blocks the blood supply to the fibroids so they shrink and soften over months. The European interventional radiology society (CIRSE) lists "urinary urgency and frequency" among the pressure complaints UFE is used for.
The research on embolization and urinary symptoms is real but modest:
- A 2025 Italian study of 37 patients reported significant improvement in bulk symptoms and urinary problems after UFE.
- A 2008 study of 101 patients found that fibroid size, location and number did not significantly change how much menstrual, bulk or urinary symptoms improved at one year.
- In the Dutch EMMY trial, the uterus shrank by about 48% on average 2 years after embolization.
Shrinkage is gradual, so pressure relief is not immediate. Embolization also has a higher chance of needing another procedure later than surgery does. In a 2014 Cochrane review of 7 randomized trials, more women needed further surgery within 2 years after embolization. Talking through these trade-offs with a doctor who offers more than one approach helps.

What you can do in the meantime
MedlinePlus lists caffeine and alcohol as causes of frequent urination, so cutting back may ease some urgency while you wait for an evaluation. A simple diary helps too. Note how often you go, whether you wake at night, any leaking, and how your symptoms change around your period. Bring it to your appointment, along with any past imaging reports. It gives your doctor a clear picture of how much the pressure is affecting your life, and that matters more than fibroid size alone when you decide whether to treat. Our article on when fibroid size calls for treatment explains why symptoms usually guide the decision.
Frequently Asked Questions
Can fibroids make you pee a lot?
Yes. Fibroids that enlarge the uterus or sit near the bladder can press on it, so you feel the need to urinate more often or more urgently. ACOG lists frequent urination and difficulty urinating among fibroid symptoms.
Can a small fibroid cause bladder pressure?
It can. Symptoms depend on the size, number and location of fibroids, so a modest fibroid in a spot close to the bladder may cause more pressure than a larger one elsewhere.
Will treating fibroids stop frequent urination?
If fibroids are the cause, treatments that remove or shrink them often ease pressure symptoms, though shrinkage after embolization happens gradually over months. If another cause such as overactive bladder is also present, that needs its own treatment.
Do medicines help fibroid bladder symptoms?
Most fibroid medicines are used to control heavy bleeding. Procedures such as myomectomy, hysterectomy, embolization and ablation are the usual ways to reduce pressure symptoms.
When is a bladder problem with fibroids urgent?
Seek same-day care if you cannot pass urine. Contact a doctor right away for fever, back or side pain, vomiting or shaking chills, and book a prompt visit for blood in the urine.
