An enlarged prostate usually does not return to its previous size on its own. However, treatment can reduce prostate size, relieve pressure on the urethra, and significantly improve urinary symptoms. For men with benign prostatic hyperplasia (BPH), options range from medication to procedures such as prostate artery embolization.
If you are waking several times a night to urinate, struggling with a weak stream, or constantly looking for the nearest restroom, the size of your prostate may be only part of the problem. What matters most is how that enlargement is affecting urine flow and your quality of life.
At Oregon Vascular Specialists, patients with BPH can be evaluated for minimally invasive treatment options, including prostate artery embolization.
Here is what to know about BPH, whether it can improve, and when it may be time to discuss enlarged prostate treatment with a doctor.
Can an Enlarged Prostate Shrink on Its Own?
Usually, no. Benign prostatic hyperplasia is closely associated with aging, and prostate growth tends to progress rather than reverse naturally.
That does not mean your symptoms will always get steadily worse. BPH symptoms can fluctuate. You may notice periods when urination seems easier and other times when frequency, urgency, or a weak stream become more noticeable.
Changes in fluid intake, medications, alcohol or caffeine use, constipation, and other health conditions can also affect urinary symptoms. Because of this, feeling better for a while does not necessarily mean the prostate itself has become smaller.
What Is Considered an Enlarged Prostate?
The prostate is a gland located just below the bladder and surrounding part of the urethra. It normally grows as men age.
Benign prostatic hyperplasia, or BPH, occurs when this noncancerous growth affects the urinary tract. As the prostate enlarges, it can compress the urethra and make it harder for the bladder to empty normally.
Common symptoms include:
- A weak or interrupted urine stream
- Difficulty starting urination
- Frequent urination
- A sudden or urgent need to urinate
- Waking frequently at night to use the bathroom
- Feeling that the bladder has not emptied completely
- Dribbling after urination
Prostate size and symptom severity do not always match. A man with a very large prostate may have relatively mild symptoms, while someone with less enlargement may experience significant urinary obstruction.
That is one reason an evaluation for enlarged prostate symptoms should consider more than prostate size alone.
Can Lifestyle Changes Make an Enlarged Prostate Smaller?
Lifestyle changes generally do not shrink an enlarged prostate, but they may make mild urinary symptoms easier to manage.
Reducing evening fluid intake may help with nighttime urination. Limiting caffeine and alcohol can sometimes reduce urgency and frequency. Regular physical activity, maintaining a healthy weight, and avoiding constipation may also support urinary health.
It is also worth reviewing medications with your physician. Some decongestants, antihistamines, diuretics, and other medications can aggravate urinary symptoms in certain patients.
These changes can help, but they should not replace an evaluation when symptoms persist, worsen, or interfere with daily life.
What Medicines Can Shrink an Enlarged Prostate?
Several medications are commonly used as BPH treatment.
Alpha blockers relax muscles around the prostate and bladder neck, which can make it easier to urinate. They often improve symptoms relatively quickly, but they do not significantly shrink the prostate itself.
Another group, called 5-alpha-reductase inhibitors, can gradually reduce prostate volume by affecting hormones involved in prostate growth. These medications tend to work more slowly and may take several months to produce their full effect.
Some patients take both types of medication.
Medication can work well, particularly when symptoms are mild to moderate. However, side effects, inadequate symptom relief, or the need for long-term medication may lead some men to explore other enlarged prostate treatment options.
When Does an Enlarged Prostate Need Treatment?
Not every enlarged prostate requires a procedure. Mild symptoms that don’t affect your quality of life may simply be monitored.
Treatment becomes more important when BPH begins interfering with sleep, work, exercise, travel, or everyday activities.
You should also talk with a doctor if you regularly experience difficulty emptying your bladder, recurrent urinary infections, bladder stones, blood in the urine, or urinary retention.
Complete inability to urinate can be a medical emergency and requires prompt evaluation.
The goal of BPH treatment is not necessarily to restore the prostate to the exact size it was when you were younger. The more practical goal is to improve urine flow, reduce symptoms, protect bladder and kidney function when needed, and help you return to normal activities.
Can a Procedure Make an Enlarged Prostate Smaller?
Yes. Several procedures can either remove prostate tissue or cause enlarged tissue to shrink.
Traditional treatments such as transurethral resection of the prostate (TURP) remove obstructing prostate tissue through the urethra. Laser procedures and other minimally invasive urologic therapies may also create more room for urine to pass.
Another option is prostate artery embolization, or PAE.
Instead of removing prostate tissue, PAE reduces blood flow to selected areas of the prostate. Over time, the treated prostate tissue shrinks, reducing pressure around the urethra.
Updated 2026 guidance from the Society of Interventional Radiology recognizes prostate artery embolization as a minimally invasive treatment for urinary symptoms caused by BPH and an effective alternative to conventional surgical treatments for appropriately selected patients.
Urologic Society Recommendations on Prostate Artery Embolization (PAE)
The American Urological Association (AUA) also recognizes prostate artery embolization as a treatment option for certain men with benign prostatic hyperplasia (BPH). In its updated 2026 guidance, the AUA recommends PAE as a Grade B evidence-supported option for men with BPH and a prostate volume of 50 cc or greater.
The AUA guidance includes several important considerations:
- Indication: PAE may be recommended for men with BPH-related lower urinary tract symptoms (LUTS) and a prostate volume of 50 cc or greater.
- Evidence level: The recommendation is supported by Grade B evidence, indicating moderate-quality evidence regarding the efficacy and safety of PAE.
- Patient selection: Patients should have confirmed BPH as the primary cause of their urinary symptoms. Other potential causes, such as urethral stricture or bladder dysfunction, should be evaluated, along with relevant vascular risk factors.
- Special populations: PAE may also be considered for certain patients with urinary retention who depend on a catheter, men who prefer to avoid ongoing medication, patients experiencing bleeding from the prostate, or those who may not be good candidates for surgery because of other health conditions.
How Does Prostate Artery Embolization Shrink the Prostate?
Prostate artery embolization is performed through the blood vessels rather than through the urethra.
Using X-ray guidance, a physician guides a very small catheter through an artery, typically using access near the wrist or groin. The catheter is directed into the arteries supplying the prostate.
Microscopic particles are then delivered into targeted prostate arteries to reduce blood flow to the enlarged tissue. This gradually shrinks the prostate.
There is no surgical removal of prostate tissue.
How Much Does the Prostate Shrink After PAE?
PAE is designed to reduce prostate volume enough to relieve pressure on the urinary tract. The amount of shrinkage varies from patient to patient, and symptom improvement does not depend on returning the prostate to a specific “normal” measurement.
Urinary improvement also tends to occur gradually as the prostate responds to treatment. Some patients begin noticing changes within the first few weeks, with additional improvement developing over the following months.
A 2025 study of 1,075 patients found significant, sustained improvements in urinary symptoms and quality of life after PAE, including among patients followed for four to five years.
Will an Enlarged Prostate Grow Again After Treatment?
BPH is associated with the aging process, so prostate tissue can continue to change over time regardless of which treatment is chosen. No treatment can guarantee that urinary symptoms will never return. The length of symptom relief can differ depending on the treatment.
Long-term studies of PAE have shown sustained symptom improvement for many patients while also showing that a portion eventually need additional treatment.
This is one reason treatment decisions should consider more than immediate symptom relief. Prostate size, anatomy, overall health, severity of symptoms, sexual function, recovery priorities, and willingness to undergo future treatment can all matter.
How Do I Know Which BPH Treatment Is Right for Me?
There is no single best enlarged prostate treatment for every patient.
Medication may be enough for one person. Another may benefit more from a urologic procedure. For others, prostate artery embolization may offer an appealing balance between symptom relief and a less invasive recovery.
A proper evaluation may include your medical history, urinary symptoms, prostate size, medications, laboratory testing, and imaging. Your physician may also want to rule out other causes of urinary problems before recommending treatment.
This distinction is important because frequent urination or a weak stream does not automatically mean BPH is responsible.
When Should I See an Enlarged Prostate Doctor?
Consider scheduling an evaluation if urinary symptoms have become persistent or are beginning to change how you live.
Maybe you are waking three or four times a night. Perhaps road trips now require constant restroom planning. Your stream may have weakened, or your medication may no longer be providing enough relief.
Those changes are worth discussing.
You also do not have to wait until symptoms become severe to learn about your options. Understanding the cause of your urinary problems and the treatments available can help you make a more informed decision before BPH becomes harder to manage.
Is Prostate Artery Embolization an Option in Oregon?
Oregon Vascular Specialists offers prostate artery embolization for appropriately selected patients with BPH.
PAE is performed through a small catheter and does not require surgical removal of prostate tissue. It may be considered by men looking for an alternative to ongoing medication or more invasive prostate procedures.
Oregon Vascular Specialists has locations in Portland, Wilsonville, Salem, Bend, Redmond, and Klamath Falls, making evaluation and minimally invasive vascular care accessible to patients across Oregon.
If an enlarged prostate is affecting your sleep, urinary habits, or daily routine, the next step is not simply figuring out whether your prostate can become “normal” again. It is finding out what is causing your symptoms and which treatment can provide meaningful relief.
Schedule a consultation with Oregon Vascular Specialists to learn whether prostate artery embolization may be an appropriate BPH treatment for you.
Frequently Asked Questions About Enlarged Prostate and BPH
Can an enlarged prostate ever become normal again?
An enlarged prostate usually does not shrink back to its previous size without treatment. Medications or procedures can reduce its size or relieve the obstruction it causes, which may significantly improve urinary symptoms.
What happens if an enlarged prostate is left untreated?
If an enlarged prostate is left untreated, symptoms may gradually worsen over time. Some men develop increasing difficulty urinating, more frequent nighttime trips to the bathroom, or a feeling that the bladder does not fully empty. In more advanced cases, untreated BPH can contribute to urinary retention, recurrent urinary tract infections, bladder stones, or kidney problems.
What is the fastest way to shrink an enlarged prostate?
The appropriate treatment depends on the cause and severity of your symptoms. Some medications gradually shrink prostate tissue, while procedures such as prostate artery embolization or urologic treatments may provide another approach. An evaluation is needed to determine which option fits your situation.
Can prostate artery embolization permanently shrink the prostate?
PAE causes treated prostate tissue to shrink and can provide long-lasting symptom relief, but BPH can continue to progress with age. Some patients may eventually need additional treatment.
At what point should an enlarged prostate be treated?
Treatment may be appropriate when symptoms affect sleep or daily life, medication is not providing adequate relief, or complications such as urinary retention, recurrent infections, bladder stones, or problems emptying the bladder develop.
