What is an Enlarged Prostate?
The prostate is a gland found below the urinary bladder in men. The urethra—the tube carrying urine out of the bladder—passes through the prostate.
With age, the prostate commonly grows larger. This non-cancerous growth is called benign prostatic hyperplasia (BPH). The enlarged tissue may narrow the urethra or increase resistance at the bladder outlet, making it harder for the bladder to empty.
BPH does not mean prostate cancer.
BPH is benign and does not turn into cancer. Nevertheless, the two conditions can occur in the same age group and may produce overlapping symptoms. Your doctor decides whether additional prostate assessment is appropriate.
What Symptoms Can It Cause?
Urinary symptoms in men are collectively called lower urinary tract symptoms (LUTS). They are often grouped according to when they occur.
Symptoms while passing urine
Bladder storage symptoms
- Passing urine more often than usual—urinary frequency.
- A sudden difficult-to-defer need to pass urine—urgency.
- Waking at night to pass urine—nocturia.
- Occasional leakage associated with urgency.
Symptoms after passing urine
- A feeling that the bladder has not emptied completely.
- Dribbling after apparently finishing urination—post-micturition dribble.
Does a Larger Prostate Always Cause Worse Symptoms?
No. A man with a considerably enlarged prostate may have only mild symptoms, while another man with a smaller prostate may find urination very difficult.
Symptoms depend on more than prostate size. The shape of the enlargement, bladder muscle function, urinary infection, medicines, diabetes, urethral narrowing and other bladder conditions may all contribute.
Doctor's Insight
Treatment is based on the whole clinical picture: how troublesome the symptoms are, urine flow, residual urine, prostate anatomy, complications and the patient's priorities—not prostate size alone.
Seek prompt medical attention
When is an Enlarged Prostate Urgent?
Seek urgent assessment if you:
- Cannot pass urine at all—acute urinary retention.
- Have fever or chills with painful, frequent or urgent urination.
- See blood in the urine—visible haematuria.
- Develop marked pain or swelling in the lower abdomen.
- Have persistent vomiting, severe weakness or reduced urine output.
Sudden inability to pass urine is not something to watch at home. The bladder usually needs prompt drainage and the underlying cause must be assessed.
Questions Your Doctor May Ask
The pattern and effect of your symptoms help guide the investigation and treatment plan.
How long have the symptoms been present?
A sudden change may suggest infection, retention or another acute problem, while gradual progression is more typical of benign prostate enlargement.
How much do the symptoms bother you?
Treatment is influenced by sleep disturbance, disruption of work or travel, urgency, leakage and the overall effect on quality of life.
Have you had infection, stones, blood in urine or retention?
These may indicate a complication or a different urinary condition requiring further evaluation.
Which medicines do you take?
Diuretics and some cold, allergy or other medicines can worsen urinary symptoms. Do not stop prescribed medication without medical advice.
How is the Cause Evaluated?
Not every patient needs every investigation. Testing is selected according to symptoms, examination findings and the proposed treatment.
Your doctor reviews the urinary pattern, medicines, medical history and how much the symptoms affect daily life. A symptom score or bladder diary may be helpful.
Examination may include the abdomen, genitalia and a digital rectal examination (DRE) to assess the prostate.
Urinalysis helps look for infection, blood, glucose and other findings that may point to a different or additional condition.
Prostate-specific antigen (PSA) is not a test that diagnoses BPH by itself. It may be offered when the result would influence prostate cancer assessment or treatment decisions, after discussing its implications.
Ultrasound can assess the urinary tract, bladder, prostate and the urine remaining after urination—post-void residual (PVR).
Uroflowmetry measures the urinary flow. Blood tests, cystoscopy, urodynamics or additional imaging are used only when clinically indicated.
How is an Enlarged Prostate Treated?
Treatment depends on symptom severity, quality of life, prostate size and anatomy, urine flow, residual urine, complications, medical conditions and the patient's preferences.
These medicines and procedures can have important effects on blood pressure, ejaculation, sexual function and future PSA interpretation. Treatment should be prescribed and monitored by a qualified medical professional.
When Might a Procedure Be Recommended?
A procedure may be considered when symptoms remain troublesome despite appropriate medical treatment, medicines are unsuitable, or the patient prefers a procedural solution after discussing benefits and risks.
Intervention may be more strongly indicated when BPH contributes to:
- Repeated or persistent urinary retention.
- Recurrent urinary tract infections.
- Repeated bladder stones.
- Persistent visible bleeding attributed to the prostate after appropriate evaluation.
- Changes affecting the kidneys or upper urinary tract.
- Significant bladder emptying problems or worsening bladder function.
Common endoscopic approaches include transurethral resection of the prostate (TURP) and laser procedures. No single procedure is best for every patient.
Read the detailed TURP guide →What Complications Can Occur?
Many men with BPH never develop serious complications. When bladder emptying becomes significantly affected, possible problems include:
- Acute or chronic urinary retention.
- Urinary tract infection.
- Bladder stones.
- Blood in the urine—haematuria.
- Bladder muscle changes and incomplete emptying.
- Kidney or upper urinary tract effects in selected advanced cases.
Did You Know?
Waking repeatedly at night to pass urine is called nocturia. An enlarged prostate is one possible cause, but evening fluid intake, sleep disorders, diabetes, leg swelling and other medical conditions can also contribute.
Myth vs Fact
Frequently Asked Questions
Does BPH affect every older man?
Prostate enlargement becomes more common with age, but not every man develops troublesome urinary symptoms or requires treatment.
Can BPH cause erectile dysfunction?
Urinary symptoms and erectile dysfunction may occur together, particularly with increasing age and shared health conditions. One does not always directly cause the other. Mention both concerns during consultation because treatment choices may be influenced by them.
Will I need a PSA test?
Not automatically. PSA may be recommended when prostate cancer assessment would influence your care or when it helps treatment planning. Your doctor should discuss what the test can and cannot tell you.
Can medicines cure an enlarged prostate?
Medicines can improve symptoms, and some can reduce prostate size or the risk of progression over time. They do not provide the same result for every man and usually require follow-up.
When should I seek urgent help?
Seek urgent medical attention if you cannot pass urine, have fever and chills with urinary symptoms, see blood in the urine or develop severe lower abdominal pain.
