Just as its name indicates, a urinary tract infection is an infection anywhere in the urethra, bladder, ureters, or kidneys. Its severity can range from not noticeable to life threatening. The most common areas affected are the urethra and bladder, and more often in women than men. Some of the potentially noticeable signs include a burning sensation during urination or blood in the urine.

Cystitis is an inflammation that affects the bladder and a type of lower urinary tract infection or UTI. Symptoms of interstitial cystitis can include a burning sensation during urination, more frequent or intense urgency, or even blood in the urine. Pain in the lower abdomen is possible, too. Because any of these can easily accompany other conditions, it is important to get a professional diagnosis.
