Benign Prostatic Hyperplasia (BPH), also known as an enlarged prostate, is a common condition as men age. Because the prostate surrounds the urethra, its enlargement can compress the “water pipe,” leading to a variety of urinary issues. These symptoms are often grouped into categories known as storage (filling) symptoms and voiding (obstructive) symptoms. Understanding these signs is the first step in managing the condition and improving your quality of life.

Voiding (Obstructive) Symptoms
Voiding symptoms occur when the enlarged prostate physically obstructs the flow of urine out of the bladder. These are often the first signs men notice as the gland begins to grow.
- Hesitancy: You may find it takes a long time for the urine flow to start, even when you feel a strong urge to go.
- Weak or Slow Flow: The stream of urine becomes thinner or less powerful than it used to be.
- Intermittency: The urine stream stops and starts several times during a single trip to the toilet.
- Straining: You may feel the need to push or strain your abdominal muscles to begin or maintain the flow of urine.
- Incomplete Emptying: A persistent feeling that your bladder is not entirely empty after you have finished urinating.
Storage (Filling) Symptoms
As the prostate continues to grow and obstruct the urethra, the bladder must work harder to push urine out. Over time, the bladder muscle can become thicker and more sensitive, leading to storage symptoms.
- Frequency: The need to pass urine more often than usual, typically more than eight times in a 24-hour period.
- Urgency: A sudden, compelling desire to urinate that is difficult to delay.
- Nocturia: The need to wake up one or more times during the night specifically to pass urine.
- Urge Incontinence: A sudden urge to urinate followed by the involuntary leakage of urine.
Post-Micturition Symptoms
These symptoms occur immediately after you have finished urinating. They are often bothersome and can lead to embarrassment or hygiene concerns.
- Terminal Dribbling: Urine continues to trickle or drip slowly at the end of the stream, making it difficult to finish cleanly.
- Post-Micturition Dribble: The involuntary loss of a small amount of urine after you have already left the toilet, often caused by urine being “trapped” in the curved part of the urethra.
Summary
The urinary symptoms of BPH are diverse and can significantly impact daily life. Whether you are struggling with a weak flow (voiding symptoms) or find yourself waking up multiple times a night (storage symptoms), these issues are a direct result of the prostate’s growth affecting the urethra and bladder. While these symptoms are common and usually benign, they can be managed effectively with the right clinical support. Monitoring your symptoms and discussing them with a GP ensures that your treatment is tailored to your specific needs.
If you experience a complete inability to pass urine, seek emergency medical help immediately.
Is a weak flow always caused by BPH?
No, a weak flow can also be caused by a urinary tract infection, urethral stricture, or, in rare cases, prostate cancer.
What is nocturia?
Nocturia is the medical term for waking up during the night to urinate. It is one of the most common and bothersome symptoms of BPH.
Why does BPH cause urgency?
When the prostate blocks the urethra, the bladder has to work harder to empty. This can make the bladder muscle overactive and sensitive, leading to sudden urges.
Does the size of the prostate determine the severity of symptoms?
Not always. Some men with very large prostates have few symptoms, while others with only minor enlargement experience significant obstruction.
Can lifestyle changes improve these symptoms?
Yes, reducing caffeine and alcohol, limiting evening fluids, and bladder training can help manage mild to moderate BPH symptoms.
What is ‘double voiding’?
It is the technique of waiting a few moments after urinating and then trying to go again to ensure the bladder is as empty as possible.
When should I see a doctor about these symptoms?
You should see a doctor if your symptoms are bothersome, if you see blood in your urine, or if you feel you cannot empty your bladder at all.
