Increasing fluid intake by 1.5L/day can prevent recurrent UTIs in women

A recent Alberta Tools for Practice1: Based on 1 RCT in women with recurrent UTIs (average 3.3 per year) and low fluid intake (less than 1.5L/day), increasing water intake by an additional ~1.5 L/day results in 1.5 fewer UTIs and 1.7 fewer antibiotic prescriptions per patient after 1 year compared to those who don't change intake.2 

Over 90% of women with increased water intake will have fewer than 3 episodes of UTIs per year.
