Persistent urinary incontinence
Urinary incontinence can also be a persistent condition caused by underlying physical problems or changes, including:
- Pregnancy. Hormonal changes and the increased weight of the fetus can lead to stress incontinence.
- Childbirth. Vaginal delivery can weaken muscles needed for bladder control and damage bladder nerves and supportive tissue, leading to a dropped (prolapsed) pelvic floor. With prolapse, the bladder, uterus, rectum or small intestine can get pushed down from the usual position and protrude into the vagina. Such protrusions may be associated with incontinence.
- Changes with age. Aging of the bladder muscle can decrease the bladder's capacity to store urine. Also, involuntary bladder contractions become more frequent as you get older.
- Menopause. After menopause, women produce less estrogen, a hormone that helps keep the lining of the bladder and urethra healthy. Deterioration of these tissues can aggravate incontinence.
- Enlarged prostate. Especially in older men, incontinence often stems from enlargement of the prostate gland, a condition known as benign prostatic hyperplasia.
- Prostate cancer. In men, stress incontinence or urge incontinence can be associated with untreated prostate cancer. But more often, incontinence is a side effect of treatments for prostate cancer.
- Obstruction. A tumor anywhere along your urinary tract can block the normal flow of urine, leading to overflow incontinence. Urinary stones — hard, stonelike masses that form in the bladder — sometimes cause urine leakage.
- Neurological disorders. Multiple sclerosis, Parkinson's disease, a stroke, a brain tumor or a spinal injury can interfere with nerve signals involved in bladder control, causing urinary incontinence.
