Acute bacterial prostatitis: Category 1
Bacteria normally found in your large intestine typically cause acute prostatitis. Most commonly, acute prostatitis originates in the prostate, but occasionally the infection can spread from a bladder or urethral infection.
Chronic bacterial prostatitis: Category 2
It's not entirely clear what causes a chronic bacterial infection. Sometimes it develops after an episode of acute prostatitis when bacteria remain in the prostate. Catheter tubes used to drain the urinary bladder,
injury to the urinary system (such as from bike riding or horseback riding ) or infections in other parts of the body can be the source of the bacteria.
Chronic nonbacterial prostatitis: Category 3
The cause or causes of this condition are not well-defined. Some theories regarding the causes are as follows:
-
Other infectious agents. Some experts believe nonbacterial prostatitis may be caused by an infectious agent or agents that do not show up in standard laboratory tests.
-
Heavy lifting. Lifting heavy objects when your bladder is full may cause urine to back up into your prostate causing inflammation.
-
Interstitial cystitis. This condition that's more frequently diagnosed as a cause of chronic pelvic pain in women is being more frequently recognized in men.
-
Physical activity. Although regular exercise, especially jogging or biking, is great for the rest of your body, it may irritate your prostate gland.
-
Pelvic muscle spasm. Urinating in an uncoordinated fashion with the sphincter muscle not relaxed may lead to high pressure in the prostate and the development of inflammation and prostatitis symptoms.
tructural abnormalities of the urinary tract. Narrowings (strictures) of your urethra may cause increased pressure during urination and result in inflammation and symptoms.
Prostatitis is not contagious and is not a sexually transmitted disease.
