If you’re dealing with an enlarged prostate, you’re far from alone. In fact, benign prostatic hyperplasia (BPH) affects about half of men over 50—and nearly 90% by age 80. It’s a natural part of aging, but that doesn’t make it any less frustrating.
Frequent bathroom trips, weak urine flow, and interrupted sleep can seriously affect your quality of life. So it’s no surprise that many men ask the same question: Can the prostate actually shrink back to its normal size? And if so, how?
This article breaks down what’s really happening when your prostate enlarges, what current research says about BPH reversal, and what options are available—from lifestyle changes to medications and procedures. We’ll also clear up a few myths and offer practical guidance to help you feel more in control of your health.
Understanding your options is the first step toward relief. Let’s dive into what’s possible when it comes to managing—and potentially reversing—an enlarged prostate.
What Causes BPH? Understanding Why the Prostate Enlarges
Wondering what causes BPH as you age? You’re not alone. While the exact reasons aren’t fully understood, research points to several key factors—most of them tied to natural aging and hormonal shifts.
The most well-known culprit is dihydrotestosterone (DHT), a hormone derived from testosterone. As men age, DHT levels remain active in the prostate even as overall testosterone declines. Over time, DHT stimulates the growth of prostate cells, which leads to gland enlargement. This hormonal imbalance is widely recognized as a primary driver of why the prostate enlarges in older men.
Additionally, age-related cellular changes play a big role. As cells divide and regenerate over the years, structural changes occur, often resulting in increased prostate volume. According to a 2023 study published in The Journal of Urology, cellular aging and inflammation also contribute to the progression of benign prostatic hyperplasia1.
Genetics and lifestyle add to the risk. If your father or brother had BPH, your chances increase. Obesity, lack of physical activity, and diets high in saturated fats may also speed up prostate growth.
In short, BPH is the result of a mix of hormones, aging, and personal risk factors. While it’s not cancerous, it can significantly affect daily life—and understanding its cause is key to managing it effectively.
Can the Prostate Return to Normal Size?
Here’s the honest answer: in most cases, the prostate does not return to its youthful size entirely—but that doesn’t mean you’re stuck with uncomfortable symptoms forever. While full reversal may be rare, shrinking prostate size and relieving pressure on the urethra is absolutely possible with the right treatment approach.
Medical therapies are often the first line of defense. 5-alpha-reductase inhibitors, like finasteride and dutasteride, can gradually reverse BPH by lowering levels of dihydrotestosterone (DHT)—the hormone that stimulates prostate growth. Studies show that these medications can reduce prostate volume by up to 25% over 6–12 months. This decrease may not restore your prostate to its original size, but it often leads to major symptom relief.
Other treatments, such as minimally invasive procedures like Rezūm (water vapor therapy) or UroLift, offer targeted ways to improve urine flow without significantly altering prostate size. These techniques reshape or relieve pressure on the urethra rather than shrinking the gland itself—but they still lead to meaningful improvement in quality of life.
In short, while complete prostate shrinkage is unlikely, many men experience lasting relief and restored bladder function through treatment. The key is early action, the right therapy, and close monitoring with your urologist.
Medical Treatments That Can Shrink the Prostate
If you’re exploring ways to manage an enlarged prostate, you’ll find several evidence-based medical treatments that can relieve symptoms—and in some cases, shrink the gland itself. Let’s break down the most common and effective options.
1. 5-Alpha Reductase Inhibitors (e.g., Finasteride, Dutasteride)
These are among the most effective medications for BPH when it comes to actually reducing prostate size. Drugs like finasteride for BPH work by blocking the conversion of testosterone into dihydrotestosterone (DHT), the hormone that fuels prostate growth. Over time—typically 6 to 12 months—these medications can reduce prostate volume by up to 25% and significantly improve urinary symptoms.
Side effects may include decreased libido, erectile dysfunction, or reduced semen volume, but these are reversible if the drug is discontinued.
2. Alpha Blockers (e.g., Tamsulosin, Alfuzosin)
While alpha blockers don’t shrink the prostate, they offer fast relief by relaxing the smooth muscle in the bladder neck and prostate. This improves urine flow and reduces urgency and frequency. They’re often prescribed alongside 5-alpha reductase inhibitors for a dual benefit. Common side effects include dizziness and nasal congestion.
3. Surgical Options
For moderate to severe BPH or when medications aren’t effective, surgery may be the best option:
- TURP (Transurethral Resection of the Prostate): The gold standard surgical treatment. It involves removing excess prostate tissue via the urethra to relieve obstruction. It has a high success rate but may require a hospital stay.
- HoLEP (Holmium Laser Enucleation of the Prostate): A laser-based version of TURP, effective for larger glands with fewer bleeding risks.
- UroLift: A newer, minimally invasive procedure that lifts and holds enlarged prostate tissue away from the urethra—no cutting or removal involved. Recovery is quick, and it preserves sexual function.
Choosing the right medication for BPH or considering a TURP procedure depends on the severity of your symptoms, prostate size, age, and overall health. A urologist can help tailor the best plan for you.
Natural Ways to Reduce Prostate Size and Support BPH Management
While medications and procedures are often effective, many men explore natural ways to reduce prostate size or complement their treatment plan. The good news? Several lifestyle changes and natural remedies may offer relief—especially for mild to moderate symptoms.
1. Eat for Prostate Health
A diet rich in zinc, omega-3 fatty acids, and antioxidants may help support prostate function and reduce inflammation. Foods like pumpkin seeds, salmon, tomatoes (rich in lycopene), and leafy greens are excellent choices. Some studies suggest that the Mediterranean diet is especially beneficial for BPH management.
2. Herbal Supplements (with Caution)
Supplements like saw palmetto and beta-sitosterol are commonly marketed for prostate health. Some small studies report symptom improvement, but the evidence is mixed, and these products aren’t regulated like prescription medications. Always talk to your doctor before starting supplements, especially if you’re taking other medications.
3. Limit Irritants
Reducing alcohol, caffeine, and fluid intake before bedtime can help minimize nighttime urination and urgency. These substances can irritate the bladder and worsen symptoms of an enlarged prostate.
4. Stay Active and Maintain a Healthy Weight
Regular exercise—especially aerobic activity—and maintaining a healthy body weight are linked to lower BPH risk and better symptom control. Excess abdominal fat may increase estrogen and insulin levels, which can contribute to prostate enlargement.
While these lifestyle changes for BPH won’t reverse the condition entirely, they can significantly improve comfort and quality of life when combined with medical treatment.

BPH FAQs:
Can BPH go away on its own?
No, BPH (benign prostatic hyperplasia) usually doesn’t go away without treatment. While symptoms may come and go, the condition tends to gradually worsen with age. However, lifestyle changes and medical therapy can significantly reduce symptoms and improve quality of life.
How long does it take for finasteride to work?
Finasteride doesn’t offer quick relief—it typically takes 3 to 6 months of consistent use to start noticing improvements. The drug works by reducing DHT levels to gradually shrink the prostate. Full benefits may take up to a year, so patience and regular follow-up with your doctor are key.
Is surgery the only way to shrink the prostate?
No. Surgery like TURP or HoLEP is usually reserved for moderate to severe cases or when medication fails. Many men find success with 5-alpha reductase inhibitors (like finasteride), which can reduce prostate size without the need for surgery. Minimally invasive procedures like UroLift are also alternatives.
Do natural supplements actually help?
Some men report mild symptom relief from natural supplements like saw palmetto or beta-sitosterol, but scientific evidence is mixed. These supplements may help support overall prostate health, but they are not substitutes for medical evaluation and treatment. Always consult your doctor before trying them.
Final Thoughts on Treating an Enlarged Prostate
Living with BPH doesn’t mean living in discomfort. While your prostate may not return to its original size, there are many effective strategies for treating an enlarged prostate and reducing symptoms. From medications like finasteride to lifestyle changes and surgical options, the right solution depends on your health, age, and personal preferences.
The key is to take action early. Don’t ignore the signs or wait for things to get worse—talk to your doctor about the best treatment plan for you. A proactive approach can prevent complications and help you regain control over your daily routine.
Prioritizing prostate health now can make a big difference later. With the right care, most men find real relief and a better quality of life.
