A weak bladder refers to urinary incontinence and is common in both men and women. Urinary incontinence is the accidental release of urine from the bladder. Usually, a weak bladder is the sign of a secondary underlying condition in the urinary tract, rather than the result of a disease itself.
Removal of Prostate Gland
One common cause of incontinence in men is the removal of the prostate gland. If the nerves in the sphincter have been damaged or become weak, the bladder cannot support the urine and any extra pressure, such as that caused by a sneeze, may result in a leaking bladder.
Blockage of Urethra
Another reason for incontinence is the enlargement of the prostate gland. When the urethra is blocked by an enlarged prostate, the urethra narrows and bladder pressure causes the extra urine to pass out of the penis.
Weak Bladder Muscles:
When the bladder muscles are weak, urine cannot be held in the bladder and incontinence occurs. One cause of a weak bladder is old age.
Drugs
Some drugs--e.g. narcotics, prescription medicines and diuretics--may cause a temporarily weak bladder as a side effect.
Diabetes and Nerve Damage
Men who have had diabetes for a long time and have had neuropathy problems as a result may experience a weak bladder.
Nervous Disorders
Nervous disorders like Parkinson's and multiple sclerosis can affect the brain and nervous system, causing bladder muscles to weaken. The ability to control urination is then diminished.
Prostrate Cancer Treatment
Radiation treatments for prostrate cancer also can cause bladder problems, which may be temporary or permanent.
