Bladder retraining is often helpful for people who have difficulty controlling their bladder. Many times this technique is used for patients with either urinary incontinence or interstitial cystitis. Urinary incontinence refers to the loss of urine control; this condition affects about 25 million American adults to some degree, and while it can strike individuals of any age, women over 50 are most likely to develop it. Interstitial cystitis, meanwhile, is a chronic inflammation of the bladder wall, characterized by bladder pressure, bladder pain and pelvic pain. It can lead to decreased bladder capacity, and most commonly affects women between the ages of 30 and 40.
