Bacterial prostatitis is usually caused by bacterial infection. Common causes include retrograde infection of bacteria from the urethra, spread of inflammation to other parts of the body, and invasion of pathogens when the immune system is weakened.

Specifically, it is mainly related to the following points:

1. Retrograde spread of urethral infection: Bacteria enter from the urethral opening and spread upwards along the urethra to infect the prostate. This may be related to personal hygiene habits or certain medical procedures.
2. Effects of other infections: Infections in other parts of the body, such as urinary tract infections or inflammation in distant parts of the body, may affect the prostate through blood or lymphatic circulation.
3. Weakened local resistance: When the body is fatigued, sits for long periods of time, or has irregular lifestyle habits, the prostate's local defense capabilities may decrease, providing an opportunity for bacterial infection.
To maintain prostate health, it is recommended to pay attention to personal hygiene, avoid holding urine for extended periods, and avoid prolonged sitting. Drinking plenty of water and maintaining a regular sleep schedule can help boost the body's immunity. If you experience discomfort such as frequent urination or painful urination, consult a doctor promptly for proper examination and treatment; do not self-medicate.
