What causes recurrent urinary tract infections?

In general, recurrent urinary tract infections may be caused by factors such as insufficient water intake, urine retention, poor personal hygiene, urinary system stones, or neurogenic bladder, and require management according to the specific situation.

1. Insufficient water intake: Inadequate daily water consumption may lead to concentrated urine, increased concentration of harmful substances in the urine, enhanced irritation to the urinary mucosa, and reduced elimination of bacteria, making infections more likely. It is recommended to develop good lifestyle habits, ensure adequate daily water intake, increase urine output, and flush the urinary tract.

2. Urine retention: Long-term urine retention can increase bladder pressure, impair blood circulation in the bladder mucosa, and reduce its resistance, making urinary tract infections more likely. Avoid holding urine in daily life and urinate promptly when needed.

3. Poor personal hygiene: The female urethra is short and straight and located close to the anus; failure to maintain perineal cleanliness can easily lead to bacterial contamination of the urethral opening and subsequent urinary tract infection. In males, poor personal hygiene can also promote bacterial growth and increase the risk of infection. It is recommended to maintain genital hygiene, wear cotton, breathable underwear, and reduce bacterial proliferation.

4. Urinary system stones: Stones in the urinary system can obstruct urine outflow, allowing bacteria to multiply in the urinary tract and cause recurrent infections. It is recommended to take medications such as lithiasis granules or Qianshi Tong granules under medical guidance for treatment.

5. Neurogenic bladder: Neurological disorders can lead to bladder dysfunction, such as difficulty urinating or urinary retention, causing urine to remain in the bladder for extended periods, promoting bacterial growth and causing infections. It is recommended to perform intermittent catheterization and bladder training under medical supervision to help patients establish regular voiding habits and reduce residual urine volume.

If recurrent urinary tract infections occur, timely medical consultation is necessary for detailed examination to identify the underlying cause and receive targeted treatment under medical guidance to reduce recurrence of the infection.
