Recurrent urinary tract infections (UTIs) can be a persistent problem for many individuals. They are most commonly caused by the bacterium Escherichia coli, which resides in the intestinal system. If E. coli is transferred from the rectum to the vagina, it can then ascend through the urethra and infect the bladder. The risk factors for developing a UTI can vary with age and are influenced by different physiological and lifestyle factors.

Complicated bladder infections are characterized by symptoms that suggest the infection may have spread beyond the bladder. These can include fever, flank pain, chills, or fatigue. In men, pain in the perineal area, between the genitals and anus, could indicate a complicated infection. The inflammation caused by a bladder infection can lead to a host of uncomfortable symptoms.

Symptoms of a urinary tract infection often include an increased frequency of urination, a strong urge to urinate, pain during urination, and a feeling of pressure or tenderness in the lower abdomen. Nighttime awakenings to pass urine can also occur. Additionally, UTIs can lead to urine leakage, as the infection can cause the bladder muscle to contract involuntarily.

While UTIs can cause urine leakage and other bladder issues, it’s important to note that bacteria causing bladder infections are not typically sexually transmitted. In women, the short urethra and its proximity to the anus make it easier for bacteria from the intestines to reach the bladder, but these bacteria are not passed between sexual partners.

UTIs can occur anywhere along the urinary tract, which includes the kidneys, ureters, bladder, and urethra. Though sexual activity, catheter use, and other factors can trigger infections, they are not necessarily the cause of a partner’s infection.
