6 Evidence-Based Ways to Prevent UTIs

Prevention Is Possible

While UTIs are incredibly common, there are proven strategies to significantly reduce your risk. Here are 6 evidence-based prevention methods.

1. Stay Well Hydrated

The evidence: A 2018 randomized trial in JAMA Internal Medicine found that women who increased their daily water intake by 1.5 liters had 48% fewer UTIs over 12 months.

What to do: Aim for at least 6-8 glasses of water per day. Your urine should be light yellow - dark urine means you need more fluids.

2. Urinate After Sexual Intercourse

The evidence: While the evidence is primarily observational, post-coital urination is universally recommended by urologists and gynecologists. It helps flush bacteria that may have been pushed toward the urethra during intercourse.

What to do: Urinate within 30 minutes after sex. It doesn't need to be immediate.

3. Wipe Front to Back

The evidence: Wiping from back to front can transfer E. coli from the anal area to the urethra. This is one of the most basic and important prevention strategies.

What to do: Always wipe from front to back after using the bathroom.

4. Avoid Irritating Feminine Products

The evidence: Douches, scented sprays, powders, and scented pads/tampons can disrupt the normal vaginal flora that helps protect against UTIs.

What to do: Use unscented products and skip the douche - the vagina is self-cleaning.

5. Wear Breathable Underwear

The evidence: Tight, synthetic underwear can create a warm, moist environment that promotes bacterial growth.

What to do: Choose cotton underwear and avoid sitting in wet swimsuits or workout clothes for extended periods.

6. Don't Hold Your Urine

The evidence: Urinary stasis (holding urine for long periods) allows bacteria to multiply in the bladder. Regular emptying flushes bacteria out.

What to do: Urinate when you feel the urge - don't habitually hold it. Aim to empty your bladder every 3-4 hours.

When Prevention Isn't Enough

If you get 3+ UTIs per year despite preventive measures, talk to your doctor about:

• Low-dose prophylactic antibiotics (daily or post-coital)
• Vaginal estrogen (for postmenopausal women)
• Methenamine hippurate (a urinary antiseptic)
