What is benign prostatic hyperplasia (BPH)?
Benign prostatic hyperplasia
(BPH) is an enlarged
prostate gland . The prostate gland surrounds the
urethra , the tube that carries urine from the
bladder out of the body. As the prostate gets bigger,
it may squeeze or partly block the urethra. This often causes problems
BPH occurs in almost all men as they age. BPH is not
cancer. An enlarged prostate can be a nuisance. But it is usually not a serious
problem. About half of all men older than 75 have some symptoms.
Benign prostatic hyperplasia is also known as benign prostatic
What causes BPH?
Benign prostatic hyperplasia is probably a normal part of the aging
process in men, caused by changes in hormone balance and in cell growth.
What are the symptoms?
urinary problems such as:
- Trouble getting a urine stream started and
completely stopped (dribbling).
- Often feeling like you need to
urinate. This feeling may even wake you up at night.
- A weak urine
- A sense that your bladder is not completely empty after
In a small number of cases, BPH may cause the bladder to be
blocked, making it impossible or extremely hard to urinate. This problem may
cause backed-up urine (urinary retention), leading to
bladder infections or
stones or kidney damage.
BPH does not
cause prostate cancer and does not affect a man's ability to father children.

How is BPH diagnosed?
Your doctor can diagnose BPH by asking
questions about your symptoms and past health and by doing a physical exam.
Tests may include a urine test (urinalysis), a blood test (serum creatinine), and a
digital rectal exam, which lets your doctor feel the
size of your prostate. In some cases, a prostate-specific antigen (PSA) test is
done to help rule out prostate cancer. (Prostate cancer and BPH are not
related, but they can cause some of the same symptoms.)
doctor may ask you how often you have symptoms of BPH, how severe they are, and
how much they affect your life. If your symptoms are mild to moderate and do
not bother you much, home treatment may be all that you need to help keep them
under control. Your doctor may want to see you regularly to check on your
symptoms and make sure other problems haven't come up.
