What condition is characterized by an excessive urge to urinate due to inflammation and irritation?

Cystitis is characterized by inflammation of the bladder, which often leads to an excessive urge to urinate, as well as increased frequency and urgency of urination. This condition can result from a variety of causes, including bacterial infections, chemical irritants, or even irritants like certain hygiene products. The inflammation and irritation of the urinary bladder lining create a heightened sensitivity, prompting the individual to feel the need to urinate more often than normal.

While urinary tract infections (UTIs) can cause similar symptoms and can lead to cystitis, cystitis itself is specifically the inflammation of the bladder and not necessarily linked to a systemic infection. Renal failure primarily affects the kidneys and is associated with a range of different symptoms, particularly those related to kidney function. Interstitial cystitis is a more chronic condition with symptoms similar to cystitis but is distinct in its underlying causes and duration. Thus, in the context of the question, cystitis directly corresponds to the excessive urge to urinate due to the inflammation and irritation of the bladder.
