Why Do You Get UTIs After Sex and How to Prevent Them?

Urinary tract infections (UTIs) are common bacterial infections impacting the urinary system. Many individuals, particularly women, frequently experience UTIs, sometimes noting their onset after sexual activity. Understanding why these infections occur and how to reduce their likelihood is a common concern.

How Sex Contributes to UTIs

Sexual activity can increase the risk of developing a UTI due to the movement of bacteria. During intercourse, bacteria residing in the genital and anal regions can be pushed towards the urethra. This tube, which carries urine out of the body, can then allow these bacteria to enter the urinary tract.

The proximity of the urethra to the anus in individuals with female anatomy makes them particularly susceptible. Escherichia coli (E. coli), a bacterium commonly found in the gastrointestinal tract, is a frequent cause of UTIs. While less frequent, individuals with male anatomy can also develop UTIs after sex, especially if bacteria are introduced into the urethra during activity.

Signs of a Urinary Tract Infection

Common symptoms often include a persistent and strong urge to urinate, even when the bladder is not full. Individuals may also experience a burning sensation during urination, along with passing small amounts of urine frequently.

Other indicators can include cloudy or strong-smelling urine. Some people might also notice pelvic pain or pressure, typically in the lower abdomen, which can be accompanied by lower back pain.

Strategies for Prevention

Several practices can help reduce the likelihood of developing a UTI after sexual activity. Urinating immediately after sex is a widely recommended step, as it helps flush out any bacteria that may have entered the urethra. Drinking plenty of water throughout the day also supports this flushing action by encouraging frequent urination, which helps prevent bacteria from settling in the urinary tract.

Proper hygiene is another important strategy, including wiping from front to back after using the toilet to prevent the spread of bacteria from the anus to the urethra. Washing the genital area with warm water before sex can help reduce the amount of bacteria present. Avoiding irritating feminine products such as douches, scented sprays, or powders can help maintain the natural balance of the genital area and reduce irritation to the urethra.

Seeking Professional Help

It is advisable to consult a healthcare professional if UTI symptoms are present or worsen. Persistent symptoms, increasing pain, or the appearance of blood in the urine warrant medical attention. Symptoms indicating a potentially more serious infection, such as fever, chills, nausea, vomiting, or pain in the back or side, should prompt immediate care.

Healthcare providers typically diagnose UTIs through urine tests and often treat them with antibiotics. Early and complete treatment with prescribed antibiotics is important to clear the infection and prevent potential complications, such as the infection spreading to the kidneys.
