Which lifestyle change is often suggested to help prevent urinary tract infections?

Staying hydrated and urinating frequently is a well-established lifestyle change that can significantly help in the prevention of urinary tract infections (UTIs). Hydration is crucial because it promotes larger urine output, which in turn helps flush out bacteria from the urinary tract. When the body is well-hydrated, the urine becomes more dilute, reducing the likelihood of bacteria multiplying in the bladder.

Frequent urination also plays an important role by allowing the body to regularly expel any bacteria that might have entered the urinary tract. This process diminishes the chances of infection since it prevents bacteria from having enough time to adhere to the urinary tract walls and establish an infection.

The other options, such as decreasing fluid intake or avoiding complex carbohydrates, are not associated with UTI prevention and can even be counterproductive. Limiting dairy products also does not have any significant impact on UTI risk, making staying hydrated and urinating frequently the most effective strategy in preventing these infections.
