At least 25 percent of adults, and probably many more who are too embarrassed to discuss the condition with their doctors, have urinary incontinence, says IUSM’s Dr.Ann Zerr. Many of these are women in their 30s and 40s. Urinary incontinence is the unintentional loss of urine.
Stress incontinence affects primarily women. Sneezing, coughing or lifting can cause the accidental loss of small amounts of urine due to change in the tone of muscles in the pelvis of women who have had children.
Women and men with urge incontinence experience a sudden uncontrollable urge to urinate that can be triggered by the sound of water, arrival at a specific location or other cues. Various treatment options exist for stress and urge incontinence. Some women have both types of incontinence which can be more difficult to treat.
