Benign prostatic hyperplasia (BPH) is treated with a combination of lifestyle changes, medications, and procedures, depending on how much your symptoms affect daily life. About 45% of men over 45 develop BPH, and that number climbs to roughly 80% in men over 70. The good news: treatment options range from simple behavioral adjustments for mild symptoms to minimally invasive procedures and surgery for more severe cases.
How Symptom Severity Guides Treatment
Doctors typically assess BPH symptoms using a standardized questionnaire called the International Prostate Symptom Score, which rates things like how often you wake up at night to urinate, whether your stream feels weak, and how completely your bladder empties. Scores fall into three categories: mild (0 to 7), moderate (8 to 19), and severe (20 and above). Where you land on this scale largely determines which treatment path makes sense.
Mild symptoms often respond well to lifestyle changes alone. Moderate symptoms usually call for medication, sometimes combined with behavioral strategies. Severe symptoms, or cases where complications like urinary retention have already occurred, may warrant a procedure or surgery. That said, the deciding factor isn’t just the score. It’s how much your symptoms bother you and interfere with your life.
Lifestyle Changes That Help
For mild symptoms, or as a complement to medication, a few practical adjustments can make a noticeable difference. Cutting back on caffeine and alcohol reduces the urge to urinate frequently, since both act as mild diuretics and bladder irritants. Avoiding liquids for a couple of hours before bed or before going out can help with nighttime urination and the anxiety of needing a bathroom while you’re away from home.
Bladder retraining is another useful tool. This means gradually increasing the time between bathroom visits to help your bladder hold more urine comfortably. Staying physically active also appears to help; regular exercise is associated with fewer urinary symptoms overall. These changes won’t shrink your prostate, but they can meaningfully reduce the day-to-day impact of BPH.
Medications for Moderate Symptoms
When lifestyle adjustments aren’t enough, medication is the standard next step. Two main drug classes are used, and they work in very different ways.
Alpha-Blockers
Alpha-blockers relax the muscle fibers around the prostate and bladder neck, making it easier for urine to flow. They provide rapid symptom relief, often within days to a couple of weeks. The American Urological Association lists five options in this class: alfuzosin, doxazosin, silodosin, tamsulosin, and terazosin. These drugs don’t change the size of your prostate. They simply ease the squeeze. Common side effects include dizziness, lightheadedness, and in some cases, problems with ejaculation.
5-Alpha Reductase Inhibitors
These medications (finasteride and dutasteride) work by blocking the conversion of testosterone into a hormone that drives prostate growth. Over time, they can actually shrink the prostate. The tradeoff is patience: they take three to six months to reach full effect. They’re recommended specifically for men whose prostates are enlarged beyond 30 grams on imaging or who have elevated PSA levels. Side effects can include reduced sex drive and erectile difficulties.
Combination Therapy
For men with both significant symptoms and a noticeably enlarged prostate, combining an alpha-blocker with a 5-alpha reductase inhibitor delivers better results than either drug alone. The alpha-blocker provides quick relief while the second medication gradually shrinks the prostate. Studies show this combination significantly reduces disease progression and improves urinary flow compared to taking just one medication. It’s particularly useful for men at higher risk of their BPH worsening over time.
One additional option worth knowing about: tadalafil, a medication better known for treating erectile dysfunction, is also approved for BPH at a low daily dose. It can improve urinary symptoms regardless of whether you also have ED, making it a practical choice for men dealing with both issues.
What About Saw Palmetto?
Saw palmetto is the most popular herbal supplement marketed for prostate health, and you’ll find it in nearly every “prostate support” formula on store shelves. The evidence, however, is clear. A Cochrane review of 32 randomized trials involving over 5,600 men found that saw palmetto, even at two to three times the standard dose, provided no improvement in urinary flow or prostate size compared to a placebo. A separate large trial confirmed these findings at doses up to 960 mg daily. If you’re currently taking saw palmetto and feel it helps, the benefit is likely a placebo effect. Your time and money are better spent on proven treatments.
Minimally Invasive Procedures
When medications aren’t controlling symptoms well enough, or if you’d prefer to avoid taking pills long-term, several office-based or outpatient procedures can provide lasting relief without major surgery.
UroLift
UroLift uses small implants to pin back the prostate tissue that’s pressing on the urethra, similar to pulling back curtains from a window. It’s done without removing any tissue and typically preserves sexual function. The reintervention rate (meaning you need another procedure) is about 3.6% after one year and roughly 10.9% after five years. Recovery tends to be quicker than with procedures that remove tissue, though some men experience temporary discomfort or difficulty urinating afterward.
Rezum (Water Vapor Therapy)
Rezum uses targeted bursts of steam to destroy excess prostate tissue, which the body then absorbs over the following weeks. It shows somewhat better durability than UroLift, with reintervention rates of about 2.8% at one year and 6.8% at five years. The downside is a higher rate of short-term complications. Urinary retention after the procedure occurs in about 23% of patients, meaning you may need a catheter for several days to weeks while the swelling resolves. Urinary tract infections are also more common with Rezum (7.5%) compared to UroLift (3.9%).
Aquablation
Aquablation is a newer option that combines real-time imaging with a robotic waterjet to precisely remove prostate tissue. It’s particularly useful for men with very large prostates, where other minimally invasive options may be less effective. Multinational data show sustained symptom improvement and quality-of-life gains at 12 months, with a favorable safety profile. Because the procedure is guided by imaging rather than surgeon hand movements alone, it may produce more consistent results across different prostate shapes and sizes.
Surgery for Severe Cases
Transurethral resection of the prostate (TURP) has been the gold-standard surgical treatment for decades. A surgeon inserts an instrument through the urethra and removes the inner portion of the prostate that’s blocking urine flow. No external incisions are needed.
TURP is highly effective. In a contemporary study of elderly patients, 88.8% of well-selected patients were catheter-free at 12 months. The overall complication rate was about 9.5%, with early complications occurring in roughly 7% of cases and late complications in about 3%. The most significant side effect is retrograde ejaculation, where semen flows backward into the bladder during orgasm instead of out through the penis. This is harmless but permanent in most cases, and it’s something to factor into your decision if sexual function is a priority.
TURP is typically reserved for men with severe symptoms, very large prostates, or complications like recurring urinary retention, bladder stones, or kidney problems caused by chronic obstruction.
Complications That Need Urgent Attention
Most BPH progresses slowly and stays manageable. But certain complications signal that something more serious is happening. Acute urinary retention, the sudden and complete inability to urinate, is the most common BPH complication requiring hospitalization. It causes intense pain from bladder overfilling, with bladder volumes sometimes reaching 500 milliliters to a full liter. This requires emergency catheterization and typically leads to a conversation about surgical options.
Blood in your urine (hematuria) is another recognized complication of BPH and always warrants evaluation to rule out other causes. Recurrent urinary tract infections, bladder stones, and signs of kidney dysfunction, such as swelling in the legs or changes in urine output, are all signals that your BPH has progressed beyond what conservative treatment can safely manage.
