For many people, urinary incontinence severely limits their routine activities and even damage their quality of life and self-esteem. The most common of it includes urge urinary incontinence and stress urinary incontinence. Urge urinary incontinence is usually due to overactive bladder syndrome. The symptoms of an overactive bladder are supposed to be due to involuntary contractions of the detrusor muscle in the bladder wall throughout the filling phase of the micturition cycle. Women who have given birth have postpartum stress urinary incontinence.
Acupuncture treatment may benefit in people with urinary incontinence by decreasing the expression of c-Fos in the brain, as well as controlling nitrergic neurotransmitters so as to increase nitric oxide levels in bladder tissue, therefore relaxing smooth muscle and allowing increased bladder capacity. Besides, acupuncture may be the only CAM therapy with evidence of benefit, even at a preliminary level. Also, acupuncture may be most useful when given together with appropriate exercise regimes, but larger and better designed trials are required to fully elucidate its effects for people with urinary incontinence.
