There are two basic types of urinary incontinence issues that begin to occur in women in their 30s and older- stress incontinence and urge incontinence.
Stress urinary incontinence (SUI) is a result of a weak urethral sphincter. This usually occurs after childbirth, menopause or hysterectomy. Urine will leak out during "stress" manuevers such as exercise, laughing, coughing sneezing, and sex. It can be minor or severe.
