<bot>: Hello! Welcome to Chat Doctor !  I understand your concern. Some causes of UTI can be: 1) E. Coli from gastrointestinal tract.2) Sexual intercourse.3) Women may be especially prone to Otis because they have shorter urethrae, which allow bacteria quick access to the bladder. Some advice that I can give you are: 1) Try cranberries. Cranberries may contain an ingredient that stops bacteria from attaching to the walls of the urinary tract.2) Chat Doctor.  3) Urinate when you need to.4) Take prescribed antibiotics.  Hope that clarifies your concerns. Thank you for the query. Take care
