7 major causes of urinary tract infections in women

　　1. After relieving yourself, wipe from back to front with toilet paper.

　　female It has unique physiological characteristics. The urethral opening is close to the anus. The urethra is only 3-5 cm long, straight and wide. The urethral sphincter is weak, so bacteria can easily travel retrograde along the urethral opening to the bladder. Improper wiping methods after relieving yourself can greatly increase the risk of urethra contamination. In addition, women's vulva is particularly rich in sweat glands, which can easily make the vulva wet for a long time, allowing bacteria to take advantage of it.

　　2. Frequent sex or not paying attention to hygiene.

　　Female urinary tract infections caused by sexual life are relatively common, especially among newly married women. A survey from Taiwan showed that about a quarter of women have experienced "honeymoon cystitis".

　　3. Holding urine for too long.

　　When urinating, urine has a flushing effect on the urethra. If you do not urinate for a long time, the flushing effect will be reduced, which will increase the risk of bacterial growth in the urethra. In addition, because the female urethra is shorter, holding in urine can easily cause ascending urinary tract bacterial infection, and in severe cases, it may even cause pyelonephritis. Studies and surveys have shown that the incidence of urinary tract infections in people with poor urinary flow is 12 times higher than in normal people.
