What urinary pH is thought to help prevent urinary tract infections?

• A. High pH (alkaline)
• B. Neutral pH
• C. Acidity (low pH)
• D. Variable pH

Answer: (C)

A low urinary pH, indicating acidity, is indeed associated with a reduced risk of urinary tract infections (UTIs). The acidic environment in the urine can inhibit the growth of bacteria and help maintain the balance of urinary flora. Many pathogens that cause UTIs thrive in alkaline conditions, so keeping the urine more acidic can effectively reduce their ability to proliferate. While high pH (alkaline) urine can encourage the growth of certain bacteria, impacting the likelihood of infection, neutral pH does not provide the protective benefits seen with lower pH levels. A variable pH, which can fluctuate based on diet and hydration, does not provide a consistent defense against UTI-causing bacteria. Hence, maintaining acidity in the urine is a preventive strategy against urinary tract infections.
