What Are the Causes of UTIs?

Urinary tract infections (UTIs) are painful and can cause symptoms such as difficulty urinating and abdominal swelling, and they may spread into the kidneys and other organs without treatment. Although anyone can get a urinary tract infection, they are more common in women and older people, as well as those who have poorly functioning immune systems.

Catheters

• Catheters are a type of medical device used in the hospital to remove urine from people who are unable to use the toilet. When catheters are inserted, they can get contaminated with bacteria from the skin of the patient or medical staff. The bacteria can then get into the urinary tract when the catheter is inserted.

Diabetes

• Diabetes is a long-term disease that can cause complications such as urinary tract infections. When the level of sugar in the blood is high for a long period of time, this gives bacteria the nutrients it needs to multiply in the urinary tract. Diabetes can also lower the body's ability to kill bacteria that cause urinary tract infections.

Improper Hygiene

• Improper hygiene is a cause of urinary tract infections, especially in girls and women. Wiping from the anus toward the front can spread bacteria into the urethra and cause infection. Holding urine rather than going when the urge strikes may also be a cause of urinary tract infections.

Irritants

• Women who use spermicidal jellies as birth control may experience irritations to the urethra, which can result in a urinary tract infection. Using scented or perfumed sprays, detergents or soaps can irritate the urethra and cause urinary tracts, especially in women. Kidney stones can also irritate the urinary tract and lead to infections, especially of the stones obstruct the flow of urine.

Personal Habits

• Wearing underwear made of synthetic materials, such as nylon or spandex can promote the growth of bacteria that cause urinary tract infections. Wearing tight underwear or thongs can also promote the growth of bacteria near the opening of the urinary tract and cause infections in both men and women. Wet bathing suits or sweaty workout clothing can also allow bacteria to grow and cause a urinary infection.

Sexual Contact

• Sexual contact may be a cause of urinary tract infections, especially in women. Vaginal intercourse may spread bacteria from the genitals to the urethra, resulting in infection, and intercourse can also irritate the opening of the urethra, making it easier for bacteria to get inside. Urinating after intercourse is a way that women can reduce the risk of getting a urinary tract infection after having sex.
