What is a bladder infection?
A bladder infection, also known as cystitis, refers to an infection in the bladder. It is a type of urinary tract infection (UTI) and often caused by bacterial infections. But sometimes viral infections, yeast infections, or chemical irritants can also lead to a bladder infection.
What is the urinary tract?
First, we need to know the urinary tract. The urinary tract involves kidneys, ureters, bladder and urethra. The kidneys are responsible for clean waste from blood and make urine, then the ureters carry urine from the kidneys to the bladder. The bladder can store urine and the urine will flow out of the body through the urethra.
What causes a bladder infection?
A bladder infection is often caused by bacteria, such as Escherichia coli. The bacteria usually exist in your large intestines and skin. A bladder infection occurs when the bacteria enter your bladder through the urethra and cause infections.
Because a woman’s urethra is shorter, and the outside opening is close to anus, a woman is more likely to get bladder infections than a man.
Some factors may increase the risk of a bladder infection, including:
- Insufficient fluid intake.
- A urinary catheter.
- Narrowed urethra.
- Enlarged prostate.
- Bowel incontinence.
- Weakened immune system.
- Surgery within the urinary tract.
