why UTIs happen

Our Anatomy

Our Anatomy

The female body is brilliant — but our anatomy makes us more prone to UTIs.

A shorter urethra means bacteria have a faster, easier path to the bladder. Add in proximity between the urethra and vagina, and suddenly everyday things (sex, sweat, leggings, even wiping) become risk factors no one warned us about.

Lifestyle & Hormones

Lifestyle & Hormones

Your daily routines and monthly cycles affect your urinary health more than you think.

Hormones influence vaginal pH, protective bacteria, hydration, and mucosal tissue — all of which impact your body’s natural defenses against infection. Stress, sex patterns, underwear choices, workouts, and even the way we pee (or don’t pee) all play a role.

The Microbiome

The Microbiome

A healthy vaginal microbiome is one of your strongest defenses against UTIs.

When protective Lactobacillus bacteria dominate, they keep pH balanced and harmful bacteria in check. But antibiotics, sex, stress, scented products, tight clothing, and hormonal shifts can disrupt this delicate ecosystem — making UTIs more frequent.

9 Common UTI Causes in Women

Urinary tract infections happen when bacteria attach to the urinary tract

Sex

Sex causes 85% of UTIs. Bacteria can enter the urethra during intercourse (friction pushes it all around). Also learn how to pee correctly after sex.

Menopause

Menopause can cause a UTI. Reduced estrogen thins the urinary tract and vaginal lining, making them more vulnerable to infection. Read more here

Dehydration

Drinking plenty of water helps flush bacteria from your urinary tract. Aim for six to eight glasses daily.

Holding in Your Urine

Holding urine for 6+ hours gives bacteria time to overgrow. When you gotta pee, do it. The extra miles aren't worth the risk.

Feminine Products

Bacteria thrive on dirty pads and tampons. Change tampons every 4 hours, pads every 4–6 hours.

Lube, Soap & Douches

Avoid pH-altering products like fragranced soaps, spermicides, and lose the douche—they disrupt your natural bacteria balance and increase UTI risk. Read more
