ENLARGED PROSTATE OVERVIEW

prostate enlargement
A man’s prostate gland usually starts to enlarge after he reaches 40 years of age. This condition is called benign prostatic hyperplasia (BPH).

The prostate gland secretes a fluid that helps to nourish sperm. The gland itself surrounds the urethra, which is the tube that carries urine from the bladder out through the tip of the penis. As the prostate grows larger, it may press on the urethra. This narrowing of the urethra can cause some men with prostate enlargement to have trouble with urination. Prostate enlargement may be the most common health problem in men older than 60 years of age.

CAUSES

The prostate gland, which is normally about the size and shape of a walnut, wraps around the urethra between the pubic bone and the rectum, below the bladder. In the early stage of prostate enlargement, the bladder muscle becomes thicker and forces urine through the narrowed urethra by contracting more powerfully. As a result, the bladder muscle may become more sensitive, causing a need to urinate more often and more suddenly.

The prostate grows larger due to an increase in the number of cells (hyperplasia). However, the precise reason for this increase is unknown. A variety of factors may be involved, including androgens (male hormones), estrogens, growth factors and other cell signaling pathways.

As the prostate grows larger and the urethra is squeezed more tightly, the bladder might not be able to fully compensate for the problem and completely empty. In some cases, blockage from prostate enlargement may cause repeated urinary tract infections and gradually result in bladder or kidney damage. It may also cause a sudden inability to urinate

SEE THE WHOLE STUFF

Many men with an enlarged prostate have no symptoms. If symptoms are present, they commonly include the following:

  • A weak stream of urine
  • Difficulty starting urination
  • Dribbling of urine, especially after urinating
  • A sense of not fully emptying the bladder
  • Leaking of urine
  • More frequent urination and a strong and sudden desire to urinate, especially at night and
    blood in the urine

If you experience fever/chills or nausea/vomiting, or if the prostate enlargement condition worsens and symptoms such as blood in the urine or lower back pain are present, consult a doctor immediately.

Men over 50 years of age should have their prostate checked annually by their physician even if they have no symptoms.
