What is the most effective way to prevent urinary tract infections?

Staying hydrated is the most effective way to prevent urinary tract infections (UTIs) because it helps to flush out bacteria from the urinary tract. Adequate fluid intake ensures that the bladder is emptied frequently, reducing the opportunity for bacteria to multiply and cause infection. When the body is well-hydrated, urine production increases, which can help clear potential pathogens before they can establish an infection.

In contrast, the other options may contribute to UTI prevention to some extent, but they do not directly influence the urinary system in the same way. Regular use of antibiotics can lead to antibiotic resistance and may not provide a sustainable method for prevention. While vitamin C is often thought to acidify urine and make it less favorable for bacterial growth, its effect on UTI prevention is not as strong as staying hydrated. Finally, avoiding sexual activity might reduce the risk of introducing bacteria into the urinary tract during intercourse, but it is not a practical or effective long-term prevention strategy for those who are sexually active. Therefore, staying hydrated remains the most beneficial approach to decreasing the risk of UTIs.
