How is cystitis caused?

Cystitis is usually caused by bacterial infection, foreign body invasion and radiation therapy.

1. Bacterial infection

If the bladder is invaded by bacteria, it can cause inflammatory reaction, leading to cystitis. Common bacteria include Escherichia coli, Proteus, Klebsiella, Staphylococcus, etc.

2. Foreign body invasion

If the patient's bladder is invaded by foreign bodies for a long time, it is easy to cause bladder tissue damage and cause cystitis.

3. Radiation therapy

If the patient's pelvic area has received radiation therapy, it is easy to cause bladder tissue inflammation changes, thus forming cystitis.
