Urinary Tract Infection

Urinary Tract Infection Symptoms and Causes

A urinary tract infection (UTI) results from a bacterial infection along the urinary tract. The infection occurs when microorganisms, usually bacteria from the digestive tract, cling to the opening of the urethra and begin to multiply. The urethra is the hollow tube that carries urine from the bladder to the outside of the body. The most common cause of a urinary tract infection (about 80%) is Escherichia coli (E.coli) bacterial strains that usually inhabit the colon. Common symptoms of a urinary tract infection are:

  • Frequent urge to urinate, with pain or burning when urinating
  • Cloudy urine
  • Reddish urine if blood is present
  • Unpleasant odor
  • Abdominal discomfort or bloated feeling (women)

Additionally, symptoms of urinary tract infections in men include rectal, testicular, penile or abdominal pain.
