A UTI results when bacteria move upwards in the system. • Most UTIs are caused by E. coli bacteria that is a normal resident of the intestinal tract. When this bacteria enters an area that should be sterile, infection results. Women are more likely to suffer from this type of UTI than men (think anatomy!) but it is not uncommon for men to get these infections. • Symptoms of UTIs include urinary frequency, painful urination, and often hematuria (the presence of blood in the urine). • Diagnosis is by urinalysis (looking for bacteria in the urine). • Treatment is by antibiotics. If the infection in not treated it will continue to move upwards in the system which can eventually cause a kidney infection which can cause permanent damage. • Why is it recommended to drink lots of water?
