Topic Overview
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
urinating.
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 50 have some
symptoms.1
Benign prostatic hyperplasia is also known as benign prostatic
hypertrophy.
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?
BPH causes 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
stream.
- A sense that your bladder is not completely empty after
you urinate.
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. It does not cause
erection problems.
How is BPH diagnosed?
Your doctor can diagnose BPH by asking questions about your
symptoms and past health and by doing a physical examination. Tests may include
a
digital rectal examination, which lets your doctor
feel the size of your prostate, and a urine test (urinalysis). 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.)
Your 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.

How is it treated?
As a rule, you don't need treatment for BPH unless the symptoms
bother you or you have other problems such as backed-up urine, bladder
infections, or bladder stones.
Although home treatment cannot stop your prostate from getting
larger, it can help reduce or control your symptoms. Here are some things you
can do that may help reduce your symptoms:
- Practise double voiding. Urinate as much as you
can, relax for a few moments, and then urinate again.
- Avoid
caffeine and alcohol. They make your body try to get rid of water and can make
you urinate more often.
- If possible, avoid medicines that can make
urination difficult, such as
over-the-counter antihistamines, decongestants, nasal
sprays, and allergy pills. Check with your doctor or pharmacist about any
medicines you take.
If home treatment does not help, BPH can be treated with medicine.
Medicine can reduce the symptoms, but it rarely gets rid of them. If you stop
taking medicine, symptoms return. The side effects of medicine, which include
decreased sex drive, fatigue, dizziness, and headaches, may be worse than the
symptoms of BPH.
If your symptoms are severe, your doctor may suggest surgery to
remove part of your prostate. But few men have symptoms or other problems
severe enough to need surgery.
Can BPH be prevented?
You cannot prevent BPH or the urination problems it may cause.
Some people believe that regular ejaculations will help prevent prostate
enlargement. But there is no scientific proof that ejaculation helps.
