A bladder infection occurs when bacteria cause the bladder to be inflamed. The bladder holds urine. A tube called the urethra takes urine from the bladder out of the body. Sometimes bacteria can travel up the urethra. This causes the infection. Those who are female have bladder infections more often than those who are male. This is because the female urethra is much shorter than the male urethra.
The most common cause of bladder infections in children is bacteria from the bowels. The bacteria can get onto the skin around the urethra, and then into the urine. From there it can travel up to the bladder. This can happen because of:
- Poor cleaning after using the toilet or during a diaper change.
- In young children, wiping from the back to the front. This spreads bacteria from the rectum toward the urethra.
- Not completely emptying the bladder.
- Constipation that prevents the bladder from emptying completely.
- Not drinking enough fluids to urinate often.
- Irritation of the urethra from soaps or tight clothes.
- Abnormal structure of the urinary system.
Symptoms of a bladder infection include the need to urinate often and urgently. It may be painful. The urine may have a strong smell. It may be dark, tinted with blood, or cloudy. Your child may not be able to hold urine and may wet the bed or their clothes. Your child may also have a fever and belly pain. Some children don't have symptoms. A baby may be fussy and not able to be soothed. They may cry when urinating. Your baby may also feed less or be less active.
A bladder infection is treated with antibiotics. The doctor may also prescribe a medicine to treat pain. Children get better from a bladder infection quickly. Don't stop giving antibiotic doses to your child even if they feel better. Use the medicine as instructed by your doctor.
In many cases, a bladder infection will come back. It's important to take steps to prevent it.
