Stress Urinary Incontinence: Stress urinary incontinence is the most common type of incontinence and it is induced by physical (not mental) stress.  It occurs with physical activity, such as coughing, sneezing, jumping, exercising, playing sports, standing up from a chair, walking, squatting, turning in bed, stair climbing, or lifting.  These activities put increased pressure on the bladder, overpowering the pelvic floor muscles and causing leakage.  (Covered in Chapters 2 and 3.)

Urge Urinary Incontinence: Urge urinary incontinence is leakage triggered by a strong, uncontrollable urge to immediately urinate.  This is the type of leakage that typically occurs on the way to the bathroom.  Triggers such as arriving home, running water, cold weather, mental stress, and worry can make urge incontinence worse.  There are a few conditions related to urge incontinence, such as frequency (too-many bathroom trips), urgency (overpowering urge), and nocturia  (night-time bathroom trips).  (Covered in Chapters 4 and 5.)
