Benign Prostatic Hyperplasia (BPH), also known as benign prostate enlargement, is a non-cancerous condition where the prostate grows larger with age. It’s very common in men over 50 and can affect how easily you pass urine. While not dangerous in itself, it can cause frustrating symptoms that may worsen over time if not managed properly.
Key Takeaways
- BPH is a common, non-cancerous enlargement of the prostate that often affects men as they age.
- Symptoms, known as Lower Urinary Tract Symptoms (LUTS), usually develop slowly and can include frequent urination, weak urine flow, urgency, and disrupted sleep.
- Hormonal changes are believed to be the main cause, with age, family history, obesity, and certain health conditions increasing risk.
- Diagnosis typically involves symptom assessment, a physical exam, PSA testing, and imaging to distinguish BPH from other conditions.
- Treatment options range from lifestyle adjustments and medication to minimally invasive procedures or surgery, depending on symptom severity.
What Is Benign Prostatic Hyperplasia (BPH)?
Benign Prostatic Hyperplasia is the medical term for an enlarged prostate gland that isn’t cancerous. The prostate sits just below the bladder and surrounds the urethra, and it helps produce the fluid in semen. If you’re unsure what a prostate is, it’s a small gland that plays an important role in the male reproductive system and often changes as men age. The growth in BPH occurs specifically in the inner part of the prostate, which is the area that directly encircles the urethra (your waterpipe). As this enlarges, it acts like a clamp, compressing the urethra and making it more difficult for urine to flow freely.
It’s important to understand that BPH and prostate cancer are not the same thing. Having BPH does not increase your risk of developing cancer. That said, both can occur at the same time, which is why proper diagnosis matters.
Symptoms of BPH
The benign prostatic hyperplasia symptoms men experience are known clinically as Lower Urinary Tract Symptoms (LUTS). These symptoms, which often develop slowly, can be divided into two main categories:
Voiding (or obstructive) symptoms
These are caused by the physical blockage of the urethra by the enlarged prostate. They include:
- A weak or interrupted urine stream
- Difficulty starting urination (hesitancy)
- The need to push or strain to pass urine
- A feeling that the bladder does not empty completely
- Dribbling at the end of urination
Storage (or irritative) symptoms
These are not from the blockage itself, but rather the bladder’s reaction to it. The bladder muscle has to work harder to push urine out, causing it to become overactive and irritable. This leads to:
- Frequent urination, often every one to two hours
- Sudden, compelling urgency to urinate
- Waking up frequently at night to urinate (nocturia)
Some men live with mild symptoms for years without needing treatment. For others, the impact on sleep and daily life can be disruptive.
Causes of BPH
The precise reasons the prostate enlarges are complex, but the primary drivers are understood to be hormonal changes and age. The main culprit is a hormone called dihydrotestosterone (DHT). An enzyme in the prostate called 5-alpha-reductase converts testosterone into this more potent hormone. DHT acts as a powerful signal, telling the cells in the prostate to multiply, which leads to the gradual enlargement.
Several risk factors can make BPH more likely:
- Being over 50 (affects about 50% of men by age 60)
- Family history of prostate problems
- Severe obesity
- Elevated fasting blood sugar levels
- Type 2 diabetes
- Heart disease
Chronic inflammation within the prostate tissue is also believed to be a key factor that contributes to this cycle of cell growth. And because it’s so common, talking about it early is key to better outcomes.
Complications of BPH
If a significant blockage is left untreated, the bladder may struggle to empty completely. The stagnant urine that remains, known as a post-void residual (PVR), can lead to several complications:
- Repeated urinary tract infections (UTIs)
- Sudden, painful inability to urinate (urinary retention)
- Bladder stones
- Blood in the urine (rare)
- In rare and long-standing cases, damage to the bladder or kidneys over time from back-pressure
Even if symptoms seem manageable, it is wise to speak with a urologist to monitor the condition and prevent these issues.
How BPH Is diagnosed
Doctors usually begin by asking questions about your urinary symptoms and medical history. You may be asked to fill out a symptom score questionnaire to measure how much BPH is affecting your daily life. Then a physical exam, often including a rectal exam, helps check the size of the prostate.
Additional tests may include:
- A urine test to check for infection or blood
- A blood test to measure PSA (prostate-specific antigen)
- It is important to know that PSA can be elevated by BPH, inflammation, or cancer.
- A bladder scan or ultrasound to measure how much urine remains after voiding
- Urinary flow tests to see how well urine is passing
- An MRI test if cancer is suspected, which can accurately differentiate between BPH nodules from localised prostate cancer lesions.
Management and prevention of BPH
Treatment for BPH follows a “stepped-care” approach, tailored to how bothersome your symptoms are.
Lifestyle adjustments
For men with mild symptoms, the first-line approach is conservative management. This might include:
- Cutting down on caffeine and alcohol, especially in the evening
- Avoiding large fluid intake before bedtime
- Going to the toilet regularly and not “holding it in”
- Staying active and managing weight through exercise
Medications
When symptoms worsen, medication may be the next step. Two main types are commonly used:
- Alpha-blockers (e.g. tamsulosin, alfuzosin): relax prostate and bladder muscles, improving urine flow
- 5-alpha-reductase inhibitors (e.g. finasteride, dutasteride): shrink the prostate over time by blocking DHT
These drugs can be used alone or together. Your urologist will explain how they work, what side effects to watch for, and how soon you might see results. For many men, medications reduce the need for surgery later on.
Minimally invasive procedures
If medications don’t help or aren’t suitable, minimally invasive treatments may be recommended. These are done with little or no cutting and tend to have fewer side effects. Examples include:
-
- UroLift®: Implants hold the prostate tissue away from the urethra
- Rezūm® therapy: Uses steam to destroy excess prostate tissue
- Aquablation®: Uses a robotic waterjet to remove excess prostate tissue
At The Focal Therapy Clinic, our consultant urologists have extensive experience in all modern BPH treatments complementing their expertise in focal therapy and precision prostate care. They are ideal for men looking to preserve ejaculatory function and avoid long recovery times. These techniques also suit men who want to avoid the risks of traditional surgery.
Surgery
When symptoms are severe or complications occur, surgery may be the best option. The most common is TURP (Transurethral Resection of the Prostate), where excess tissue is removed using a scope. Other methods include laser surgery and open prostatectomy in very large prostates.
Surgery offers strong symptom relief but comes with higher risks, such as incontinence or erectile dysfunction. That’s why it’s often reserved for later stages or when other options haven’t worked. A specialist will guide you through the pros and cons based on your condition.
Preventive measures
While BPH is driven by age and hormones, you may be able to slow its progression Regular monitoring helps spot issues early. Staying healthy also plays a big role. Strategies include:
- Routine prostate check-ups with your GP or urologist
- Managing a healthy weight and blood sugar levels
- Staying physically active

How BPH differs from prostate cancer
This is one of the most common questions men ask when symptoms appear. Unlike cancer, BPH doesn’t involve abnormal cell growth or spread to other parts of the body. It’s a benign condition that responds well to non-cancer treatments.
Here’s a quick comparison:
- BPH:Benign (non-cancerous) growth of the inner zone. It causes symptoms by squeezing the urethra (your waterpipe).
- Prostate cancer: Malignant (cancerous) growth, often develops in the outer zone. It is usually asymptomatic in its early stages.
It’s possible to have both BPH and localised prostate cancer at the same time. That’s why accurate testing and expert guidance are so important.
When to see a specialist
Some men delay seeking help, but certain signs mean it’s time to book an appointment. Early care helps avoid long-term problems.
You should seek medical care if you experience:
- Blood in your urine
- Inability to urinate despite the urge
- Recurrent UTIs or bladder infections
- Severe or worsening urinary symptoms
Even if symptoms are mild, a specialist can provide clarity and peace of mind.

Frequently Asked Questions
Benign prostatic hyperplasia (BPH) is a non cancerous condition where the prostate grows larger, which is a common part of ageing in men. This growth happens in the inner part of the prostate, which can squeeze the urethra and lead to bothersome urinary symptoms.
No. They are different conditions. BPH is benign and very common, while prostate cancer involves malignant cell growth that can spread.
BPH symptoms tend to fall into two groups. Some men first notice voiding symptoms such as a weak or slow stream, difficulty starting or the flow stopping and starting. Others first notice storage symptoms such as needing to urinate more often, a sudden urge to go or waking up multiple times at night.
You cannot fully prevent the prostate from enlarging with age, but you may reduce your risk or slow progression. There is a strong link between BPH and metabolic syndrome. Maintaining a healthy weight, controlling blood sugar and staying active are all recommended.
If the blockage becomes severe and the bladder cannot empty properly, leftover urine can cause complications such as recurrent urinary tract infections, bladder stones and, rarely, back pressure that may harm the kidneys. A sudden, complete inability to urinate is a medical emergency.
