Bacterial prostatitis is mainly caused by bacterial infection. Common causes include bacteria ascending from the urethra into the prostate, spread of infection from other parts of the body, or introduction of bacteria during medical procedures. It is recommended to seek medical attention promptly for examination and to pay attention to daily precautions.

The specific reasons can be categorized as follows:

1. Ascending urethral infection: Bacteria may enter through the urethral opening during urination. If not cleared in time, they may travel up the urethra to the prostate and cause inflammation.
2. Spread of other infections: such as urinary tract infections like cystitis and pyelonephritis, or bacteria from other parts of the body spreading to the prostate via the bloodstream.
3. Impact of medical procedures: If procedures such as catheterization and cystoscopy are not properly sterilized, bacteria may be introduced into the prostate area.
4. Decreased immunity: Long-term fatigue, irregular work and rest, or chronic diseases can weaken the body's defenses and increase the risk of infection.
To prevent and alleviate symptoms, please pay attention to the following: avoid holding urine for extended periods and reduce spicy and irritating foods; maintain moderate exercise to improve physical fitness; and practice good hygiene during sexual activity to help reduce the probability of infection. If you experience symptoms such as frequent urination, painful urination, or lower abdominal discomfort, please seek medical attention at a reputable hospital promptly and follow your doctor's instructions for treatment.
