What causes bladder infection in a women? she is in pain in her bladder & back

Most : Most bladder infections are caused by bacteria from the genital/anal area that get into the urethra and then the bladder. The most common reasons for a woman to develop an infection are: - poor hygiene: you always want to wipe "front to back" to avoid rubbing fecal bacteria over your vaginal and urethral areas - sexual activity: the act of sex can push bacteria into the urethra - you can avoid this by always peeing right after sex to flush it out - bad luck if you suspect a urinary tract/ bladder infection, you should call your doctor to be seen. Your doctor may want to check a urine sample to see if you are infected and what kind of bacteria has caused it. This can help the doctor know which antibiotic will work best for you.

Sex+ short urethra: The female urethra (urine tube) is very short normally and bacteria can ascend into the bladder from sexual encounters, improper post voiding wipes, etc. Once inside bacteria can cause urinary frequency and/or burning, back pain and more. This must be treated by a MD ASAP as further ascension to the kidneys is a much more serious infection.
