As a man gets older, his prostate can sometimes grow larger. Since the prostate is located just below the bladder, and surrounding the urethra, its enlargement can restrict the flow of urine from the bladder. This compression of the urethra may result in problems with urination and/or irritation of the bladder.
Common symptoms of BPH include:
• Inability to "hold it", once the need to urinate begins
• The sensation that you still need to urinate, even after you've just finished
• Frequent trips to the bathroom, especially at night
• A smaller, weaker urine stream
• Dribbling after urination ends
• And pushing or straining in order to start urinating
In extreme cases, a man might not be able to urinate at all, which is an emergency situation that requires immediate attention.
