Enlarged Prostate (Benign Prostatic Hyperplasia)

Benign prostatic hyperplasia (BPH), commonly known as an enlarged prostate, is one of the most prevalent conditions affecting men as they age. While it is not cancer and does not increase the risk of prostate cancer, an enlarged prostate can significantly disrupt daily life through urinary problems that range from mildly inconvenient to seriously uncomfortable. Understanding the causes, recognising the signs early, and exploring the right treatment options are key steps toward protecting your quality of life.

What is an Enlarged Prostate (BPH)?

The prostate is a small, walnut-sized gland that is part of the male reproductive system. It sits just below the bladder and surrounds the urethra — the tube that carries urine out of the body. Its primary role is to produce fluid that nourishes and transports sperm.

Prostate enlargement is a natural part of ageing. The gland typically undergoes two main growth phases: once during puberty, and again starting around age 25, continuing gradually throughout a man's life. When this growth becomes significant enough to cause urinary problems, it is called benign prostatic hyperplasia (BPH).

The term "benign" is important — BPH is a non-cancerous condition. However, as the prostate grows larger, it can press against the urethra, narrowing the channel through which urine flows and creating the uncomfortable urinary symptoms many men experience. BPH is estimated to affect around 50% of men between the ages of 51 and 60, rising to up to 90% of men over 80.

Symptoms of an Enlarged Prostate

The symptoms of an enlarged prostate arise primarily from the pressure the growing gland places on the urethra and bladder. Not all men with BPH will experience symptoms, and symptom severity does not always correspond to how large the prostate has become — a slightly enlarged prostate can sometimes cause more problems than a significantly larger one.

Common enlarged prostate symptoms include:

• Frequent urination — particularly at night (a condition known as nocturia)
• Urgency — a sudden, difficult-to-control urge to urinate
• Weak or interrupted urine stream — a noticeably reduced flow
• Difficulty starting urination — straining or hesitancy before urine begins to flow
• Dribbling after urination — continued leakage once you think you have finished
• Feeling of incomplete bladder emptying — the sensation that the bladder has not fully emptied
• Urinary retention — in more severe cases, the inability to urinate at all

These urinary problems can be frustrating and disruptive, but they are manageable with the right care. If left untreated, BPH can sometimes lead to complications such as urinary tract infections, bladder stones, or kidney damage.

When to Seek Medical Advice for Prostate Issues

Many men delay seeking help for enlarged prostate problems out of embarrassment or the assumption that these changes are simply an inevitable part of getting older. While some degree of prostate growth is normal, the urinary symptoms it causes are not something you simply have to endure.

You should consult a healthcare professional if you:

• Find yourself waking up multiple times at night to urinate
• Experience a noticeably weak or slow urine stream
• Feel that your bladder never fully empties
• Notice blood in your urine
• Are completely unable to urinate — this is a medical emergency requiring immediate attention
• Have recurring urinary tract infections (UTI's)

Early evaluation not only helps manage symptoms effectively but also allows doctors to rule out other conditions, including prostate cancer, which can sometimes present with similar signs of enlarged prostate.

Diagnosing an Enlarged Prostate

An enlarged prostate diagnosis typically begins with a detailed discussion of your symptoms and medical history. Your doctor may ask you to complete the International Prostate Symptom Score (IPSS) — a standardised questionnaire that rates the severity of your urinary symptoms and their impact on your daily life. This score helps guide treatment decisions and track changes over time.

Further diagnostic steps may include:

• Digital Rectal Examination (DRE) — A brief physical examination in which the doctor gently feels the prostate through the rectal wall to assess its size, shape, and texture. Though it sounds daunting, this 10–15 second exam is a straightforward and important diagnostic tool.
• Urine tests (urinalysis) — To check for signs of infection, blood, or other abnormalities.
• Blood tests, including PSA (Prostate-Specific Antigen) — PSA is a protein produced by the prostate. Elevated PSA levels can be associated with BPH, prostatitis, or prostate cancer, so this test is often used to help distinguish between these conditions.
• Ultrasound — Transrectal or abdominal ultrasound provides detailed imaging of the prostate and urinary tract, helping to measure the size of the gland and assess residual urine after voiding.
• Uroflowmetry — Measures the speed and volume of urine flow to evaluate how well the bladder and urethra are functioning.
• Post-void residual (PVR) test — Determines how much urine remains in the bladder after urination, often performed using ultrasound.

Treatment Options for Enlarged Prostate

The right treatment for enlarged prostate depends on the severity of your symptoms, the size of your prostate, your age, overall health, and personal preferences. There is no one-size-fits-all approach, and many men with mild symptoms may not require any immediate intervention.

Watchful Waiting (Active Surveillance)

For men with mild symptoms that are not significantly affecting quality of life, a "watch and wait" approach is often recommended. This involves regular monitoring — typically annual reviews — to assess whether symptoms are worsening over time. Lifestyle adjustments such as reducing fluid intake in the evenings, limiting caffeine and alcohol, and practising bladder training can make a meaningful difference.

Enlarged Prostate Medicines

Medications are the most common first-line treatment for moderate to severe BPH symptoms. The main classes of enlarged prostate medicines include:

• Alpha-blockers (e.g. tamsulosin, alfuzosin) — These relax the smooth muscle in the prostate and bladder neck, improving urine flow. Most men notice improvement within days to a few weeks.
• 5-alpha-reductase inhibitors (e.g. finasteride, dutasteride) — These reduce levels of the hormone dihydrotestosterone (DHT), which drives prostate growth. They can shrink the prostate by up to 30% but typically take 3–6 months to achieve full effect.
• Combination therapy — Using both an alpha-blocker and a 5-alpha-reductase inhibitor together is often more effective for men with larger prostates or more severe symptoms.
• PDE5 inhibitors (e.g. tadalafil) — Originally developed for erectile dysfunction, these medications are also approved for BPH and can help with both urinary and sexual symptoms.

Minimally Invasive Procedures

For men who do not respond well to medication or prefer not to take long-term drugs, several minimally invasive procedures are available:

• Prostatic Urethral Lift (PUL / UroLift) — Tiny implants are inserted to hold back the enlarged prostate tissue, widening the urethra without cutting or removing tissue. It is associated with fewer sexual side effects than traditional surgery.
• Water Vapour Therapy (Rezūm) — Uses steam to destroy excess prostate tissue, reducing obstruction.
• Transurethral Microwave Therapy (TUMT) — Microwave energy is used to heat and reduce the overgrown prostate tissue.

Enlarged Prostate Surgery

When medications and minimally invasive treatments are insufficient, enlarged prostate surgery may be recommended. Surgical options include:

• Transurethral Resection of the Prostate (TURP) — The gold-standard surgical procedure for BPH. A thin instrument is inserted through the urethra to remove excess prostate tissue. No external incisions are made.
• Laser prostatectomy (e.g. HoLEP or GreenLight laser) — Uses laser energy to vaporise or remove prostate tissue. These techniques generally result in less bleeding and a faster recovery compared to traditional TURP.
• Open or robotic-assisted prostatectomy — Reserved for men with very large prostates, this more extensive procedure involves removing a larger portion of the gland.

Living with an Enlarged Prostate

A BPH diagnosis does not mean a permanent reduction in quality of life. With proper management, most men with an enlarged prostate can live actively and comfortably. Alongside medical treatment, certain lifestyle strategies can help reduce the impact of urinary symptoms:

• Limit fluids in the evening to reduce night-time urination
• Reduce caffeine and alcohol, both of which irritate the bladder and increase urine production
• Avoid certain over-the-counter medications such as decongestants and antihistamines, which can tighten the bladder neck and worsen symptoms
• Stay physically active — regular exercise helps maintain a healthy weight and may reduce the severity of BPH symptoms
• Practise double voiding — after urinating, wait a moment and try again to ensure the bladder empties more completely
• Keep warm — cold temperatures can worsen urinary urgency

Regular follow-up appointments are important even when symptoms are well controlled, as BPH is a progressive condition for many men and treatment plans may need to be adjusted over time.

Risk Factors and Causes of Enlarged Prostate

The precise causes of enlarged prostate are not fully understood, but several factors are consistently associated with the development of BPH.

• Age is the most significant risk factor. BPH is rare in men under 40 but becomes increasingly common thereafter. The hormonal changes that accompany ageing — particularly shifts in the balance between testosterone and oestrogen — are thought to stimulate prostate cell growth.
• Hormonal factors play a central role. Dihydrotestosterone (DHT), a potent derivative of testosterone produced by the action of the enzyme 5-alpha reductase, is considered a primary driver of prostate growth. Men who do not produce DHT do not develop BPH.

Other enlarged prostate risk factors include:

• Family history — Men with a father or brother who has BPH are at higher risk
• Obesity — Excess body weight, particularly around the abdomen, is associated with increased severity of BPH
• Metabolic syndrome — Conditions such as type 2 diabetes, high blood pressure, and high cholesterol are linked to greater BPH prevalence and progression
• Sedentary lifestyle — Physical inactivity has been associated with a higher risk of symptomatic BPH
• Diet — Diets high in red meat and low in vegetables may increase BPH risk, though research in this area is ongoing

Understanding your personal risk profile can help you and your doctor take a proactive approach to monitoring prostate health.

Enlarged Prostate and Prostate Cancer: Understanding the Difference

One of the most common concerns men have when diagnosed with BPH is whether it means they have — or will develop — prostate cancer. It is important to state clearly: BPH is not cancer, and having an enlarged prostate does not increase your risk of developing prostate cancer.

However, the two conditions can coexist in the same person, and some of their symptoms overlap, which is why proper diagnosis is essential. The key distinctions are:

• BPH involves a generalised, non-malignant enlargement of the prostate. It is a very common part of ageing and is not life-threatening, though it can significantly affect quality of life.
• Prostate cancer involves the uncontrolled growth of cancer cells within the prostate. In its early stages, prostate cancer often produces no symptoms at all, which is why routine screening is important.

Both conditions can cause an elevated PSA (Prostate-Specific Antigen) level in the blood, which is one reason a PSA test alone cannot distinguish between them. A urologist may recommend further investigations — such as an MRI or biopsy — if there is any clinical concern about prostate cancer.

The most important message is this: do not delay speaking to a doctor because you assume your symptoms are "just" BPH. An accurate diagnosis is the only way to know for certain what you are dealing with — and to receive the care that is right for you.
