Common Causes of Urinary Tract Infection

A urinary tract infection (UTI) can affect any part of your urinary system, which includes the bladder, kidneys, and urethra.

UTIs are very common, affecting up to about 10 million people each year. Infections occur most often in women and people assigned female at birth (AFAB), although they also occur in a smaller percentage of men and people assigned male at birth (AMAB).

UTIs generally develop due to the presence of bacteria, usually Escherichia coli (E. coli), in parts of your urinary system.  Bacteria can enter these parts of your body through the urethra to infect the bladder, but can also travel up from the bladder to infect the ureters and kidneys. Some common ways for a UTI to begin include:

Sexual intercourse: Sexual activity is one of the most common ways for people to develop a UTI. Bacteria can enter your urethra from your partner’s genitals or anus, allowing it to infect your urinary system. This exposure can also occur due to the usage of sex toys, particularly if they have not been adequately cleaned. Sexual UTIs may be prevented by washing your genital area daily and using contraceptives such as condoms during sex.

Bacteria from hands: Bacteria that are present on your hands or someone else’s can also enter your urethra by touching your genital area during sexual activity or while using the bathroom. This is most easily prevented by regularly washing your hands multiple times per day with soap and water.

Holding in urine: While holding in your urine does not cause a UTI on its own, it does increase your risk of developing one. Any bacteria present in your urine is forced to sit in your bladder system for a longer period of time, allowing it more time to multiply and potentially develop into an infection.

If you experience any typical symptoms of a UTI, such as a persistent urge to urinate, burning sensations while urinating, blood in your urine, or pelvic pain, you can receive treatment at Flushing Hospital Medical Center’s Ambulatory Care Center.
