Urinary tract infections (UTIs) after sex are more common than many people realize — and board-certified family physician Dr. Jen Caudle is breaking down exactly why it happens and how to reduce the risk.
In a recent Instagram video, Dr. Caudle explained that UTIs occur when bacteria enter the urethra — the short tube leading from the outside of the body to the bladder — and travel upward, causing infection.
This risk is higher for women because of anatomy: the urethra is located close to both the vagina and the rectum, and all of these areas can harbor bacteria.
“Sexual activity can increase the likelihood of bacteria entering the urethra,” Dr. Caudle noted, adding that it’s not just penetrative sex that can pose a risk. Oral sex, the use of sex toys, or even manual stimulation can also introduce bacteria into the urinary tract.
Importantly, Dr. Caudle explained that UTIs are not sexually transmitted diseases (STDs), and there are ways to lower your chances of getting one.
These include urinating before and after sex, and in some cases, cranberry juice or cranberry supplements may offer benefits.
She advised that anyone experiencing UTI symptoms — such as burning during urination, frequent urges to urinate, or cloudy and strong-smelling urine — should seek medical care promptly, as treatment is available.
