What are the causes of a urinary tract infection?

Variable: Uti's are very common, especially in young sexually active women. Causes inlcude include sexual activity, poor groin hygiene, use of certain medications or antibiotics, lack of adequate water intake, and abnormal urinary anatomy (congenital or acquired such as thru surgery). If one is experiencing frequent uti's an evaluation is recommended to possibly correct the abnormality if one is identified.

Many ways: Not urinating after sex, allowing bacteria which reached bladder during act to multiply causing uti, using bubble-bath and tub baths rather than taking a shower, severe constipation, sub-optimal toilet hygiene- not wiping front to back or holding thighs together with urinating + trapping urine behind labia, witholding urination, thongs and non-cotton underwear, not drinking or urinating enough.
