Causes of urinary incontinence in women

Urinary incontinence affects approximately 200 million women worldwide.

Such a sensitive issue entails psycho-emotional disorders.Because of the need for constant wear pads and odor patient feels constant discomfort.Sometimes this leads to the fact that it is unable to leave the house.

Causes of incontinence

In most cases, urinary incontinence occurs when the complex causes.

  • When menopause hormonal changes leads to aging of tissues, membranes atrophy of the genitourinary system, muscles and ligaments of the pelvic floor.This gives rise to incontinence.
  • When changes in the central or peripheral nervous system, which are accompanied by dysfunction of the pelvic organs (disorders of the spinal cord blood flow, his injury, inflammatory diseases, diabetes mellitus, multiple sclerosis, tumors, malformations).
  • When violations of the anatomical relationship of the bladder and urethra with other organs of the pelvic floor, or in violation of the sensitivity of nerve receptors.Such conditions occur afte
    r repeated or complicated childbirth, surgery on the pelvic organs, when doing heavy lifting, chronic inflammatory conditions, obesity.

During normal operation of the genitourinary system organs urine accumulates in the bladder wall, and stretches it.Thus receptors that are found in the bladder wall are excited, there is an urge to urinate.His person can control the will power, squeezing the sphincter (valve device governing the transition of content from one organ to another) of the bladder and the pelvic floor muscles.

muscle of the bladder, which expels urine, called the detrusor.In the normal state when the bladder is full, it is relaxed.When emptying the bladder detrusor reduced, expelling urine.

If the detrusor contracts and during the filling of the bladder, the bladder is called a hyperactive.It incontinence occurs when bladder pressure exceeds the pressure in the urethra.These processes occur in disorders of the nervous regulation of the bladder with diseases of the brain and spinal cord (central nervous system), or nerve fibers of the genitourinary system.

In these cases, urinary incontinence called urgent.Under him there is a strong urge to urinate, urine and withhold the sudden urge.

Stress incontinence occurs when there is insufficient functioning of the sphincter of the bladder, as well as excessive mobility of the bladder neck.This occurs when the pelvic organ prolapse and vaginal walls.

In such cases, the bladder neck is stretched or biased state, so the sphincter muscle can not fully be reduced.Thus, the sphincter is unable to provide sufficient pressure resistance in urinary bladder.

Such incontinence manifests itself with a slight increase of pressure in the bladder, which may be due to intra-abdominal pressure increase during coughing, laughing, physical exercise, running, sneezing, after operations on pelvic organs and radiotherapy.

In addition, urinary incontinence in women can be due to age-related changes of the pelvic floor muscles and sphincter.If incontinence occurs by two mechanisms at once, it is called mixed.
