What Is a Bladder Infection?
3. Causes
As mentioned, urinary tract infections happen when bacteria have been able to get into the urethra. This often happens when bacteria from the digestive system have moved to the opening of the urethra. It will also sometimes happen after bacteria have been introduced into the vagina during sexual intercourse.
There are numerous different bacteria that can cause a urinary tract infection. The most common culprit is Escherichia coli, which is usually found in the digestive system. Other types of bacteria including mycoplasma bacteria and chlamydia can infect the urethra but not the bladder. Regardless of the bacteria responsible, bladder infections are likely to have the same symptoms.
