Absolutely. Dehydration significantly increases your risk of developing a UTI, and it’s one of the most preventable risk factors I discuss with patients.
Here’s how dehydration sets the stage for UTI development:
When you’re dehydrated, you produce less urine, which means you urinate less frequently. This reduced “flushing” allows bacteria more time to climb up the urethra and establish infection in the bladder. Think of urination as your body’s natural defense system—frequent urination washes bacteria away before they can cause problems.
Dehydration also concentrates your urine, making it more irritating to the bladder and urethral lining. This irritation creates small inflammations that bacteria can more easily attach to and colonize.
Additionally, when you’re dehydrated, you might avoid drinking fluids to reduce the need for bathroom breaks. This creates a vicious cycle—less fluid intake leads to more concentrated urine and fewer opportunities to flush out bacteria.
I often see dehydration-related UTIs in:
- Elderly individuals who drink less to avoid frequent bathrooms trips
- Athletes who don’t replace lost fluids adequately
- People with busy jobs who forget to drink water
- Those taking diuretic medications
- Individuals recovering from illness with vomiting or diarrhea
To maintain proper hydration and reduce UTI risk:
- Aim for 6-8 glasses of water daily (more in hot weather or during exercise)
- Monitor your urine color—pale yellow indicates good hydration
- Don’t wait until you feel thirsty to drink water
- Include water-rich foods like fruits and vegetables in your diet
- Set reminders to drink water throughout the day
