Urinary incontinence

The involuntary loss of urine due to failure of normal bladder storage and sphincter control mechanisms, resulting in leakage that may be intermittent or continuous, and ranging from minimal dribbling to complete inability to retain urine. Possible causes are stress incontinence (weak pelvic floor muscles or sphincter muscles due to pregnancy, childbirth, or menopause), urge incontinence (overactive bladder, infection, Parkinson's disease, multiple sclerosis, stroke), overflow incontinence (urethra stricture, damaged bladder, BPH), and functional incontinence (dementia, immobility).
