10 Causes of Bladder Infection

Cause #4: Dehydration
Dehydration refers to the excessive loss of fluids compared to fluid intake. Although some studies were unable to find the connection between a UTI and dehydration, it has been theorized that dehydration results in decreased urine output.
Since the act of urination helps to flush out bacteria from the urethra, the decreased urine output allows the colonization and ascent of bacteria in the urethra resulting in a UTI. Depending on the activity level, climate, and other factors, the recommended fluid intake for a normal individual is about 8 glasses of water.
