cystitis

DEFINITION of cystitis

Cystitis is the medical term for inflammation of the bladder, most commonly caused by a bacterial infection. While it is a type of urinary tract infection (UTI), inflammation can also occur due to non-infectious causes like certain medications, radiation therapy, or irritation from hygiene products. Mayo Clinic Acute bacterial cystitis causes dysuria, urgency, frequency, and sometimes hematuria; it resolves with antibiotics but recurs in many cases, while interstitial cystitis (IC/BPS) is chronic with pelvic pain and no infection. Risk factors include female anatomy, sexual activity, catheters, and menopause; complications like pyelonephritis can arise if untreated.
