The most-common cause of problems with urine flow in older men is an enlarged prostate gland. Another cause in all age groups and both sexes is infection in the urinary tract, according to the National Institutes of Health. Urinary hesitancy can also be a side effect of some medicines and medical procedures.
Although dribbling, weak urine stream and delay in starting urination are very common in older men, in some cases this condition may indicate enlarged or infected prostate gland. Another common cause is infection of the urinary tract. The problem can also be caused by some medicines such as remedies for cold and allergies, tricyclic antidepressants, some drugs used for incontinence, and some vitamins and supplements, according to the National Institutes of Health. Difficulty with bladder control in women may also indicate diabetes or kidney problems, says Mayo clinic. Other causes are nervous system disorders, side effects of surgery and scar tissue in the tube leading from the bladder.
Enlarged prostate is part of growing old, just like gray hair is, says WebMD. The cells in the prostate gradually multiply in a noncancerous manner. Hence this growth is termed benign. However, such enlargement puts pressure on the urethra, thereby restricting the flow of urine. This makes it necessary for the bladder to work harder in order to push urine through the urethra.
