The severity of symptoms in people who have prostate gland enlargement varies, but symptoms tend to gradually worsen over time. Common signs and symptoms of BPH include:

  • Frequent or urgent need to urinate
  • Increased frequency of urination at night (nocturia)
  • Difficulty starting urination
  • Weak urine stream or a stream that stops and starts
  • Dribbling at the end of urination
  • Straining while urinating
  • Inability to completely empty the bladder

Less common signs and symptoms include:

  • Urinary tract infection
  • Inability to urinate
  • Blood in the urine

The size of your prostate doesn't necessarily mean your symptoms will be worse. Some men with only slightly enlarged prostates can have significant symptoms, while other men with very enlarged prostates can have only minor urinary symptoms.

In some men, symptoms eventually stabilize and might even improve over time.

Other possible causes of urinary symptoms

Conditions that can lead to symptoms similar to those caused by enlarged prostate include:

  • Urinary tract infection
  • Inflammation of the prostate (prostatitis)
  • Narrowing of the urethra (urethral stricture)
  • Scarring in the bladder neck as a result of previous surgery
  • Bladder or kidney stones
  • Problems with nerves that control the bladder
  • Cancer of the prostate or bladder

When to see a doctor

If you're having urinary problems, discuss them with your doctor. Even if you don't find urinary symptoms bothersome, it's important to identify or rule out any underlying causes. Untreated, urinary problems might lead to obstruction of the urinary tract.

If you're unable to pass any urine, seek immediate medical attention.
