About This Condition
Urinary tract infections (UTIs) are infections of the kidney, bladder, and urethra.
UTIs are generally triggered by bacteria and are more common when there is partial blockage of the urinary tract. In some people, UTIs tend to recur.
Symptoms of a UTI usually begin suddenly and include frequent urination that is irritating or burning, a persistent urge to urinate even after the bladder has been emptied, and cramping or pressure in the lower abdomen. The urine often has a strong or unusual smell and may appear cloudy. In more serious infections, fever, chills, pain in the back below the ribs, nausea, vomiting, and diarrhea may also be present.
