The urinary tract is the body’s drainage system for removing wastes and extra water. It includes the kidneys, ureters, bladder, and urethra. A urinary tract infection (UTI) occurs when bacteria infect any part of the urinary tract.
Some people are more at risk of developing UTIs:
- Gender: Females are more at risk than males because of their anatomy. Their urethras are shorter and closer to their rectum, making it easier for bacteria to enter.
- Sexual activity: Individuals who are sexually active are more at risk because of the potential for bacteria to pass during intercourse.
- Birth control: Women who use a diaphragm or spermicide as birth control are more at risk. Diaphragms push against the urethra, which makes it more difficult to empty your bladder and more likely that bacteria remain.
- Diabetes: The body is not as able to fight off germs if you have diabetes, putting you more at risk.
- Blockage in the urinary tract: Kidney stones or an enlarged prostate can trap urine in the bladder and increase the risk
- Menopause: This can cause changes to the bacteria inside the vagina, increasing the risk of a UTI.
- Age: Older adults and younger children are more at risk.
- Poor hygiene: Children going through bathroom training may struggle with proper hygiene.
- Pregnancy: The uterus sits on top of the bladder, and as it grows during pregnancy, it can block the drainage of urine. This can cause an infection.
- Lack of fluids: If you don’t drink enough water, you may not urinate enough to flush bacteria from your system.
See your doctor if you are a high-risk individual and/or are experiencing symptoms.

Common symptoms of UTIs include:
- Strong urges to urinate
- Burning feeling during urination
- Cloudy or bright red urine
- Strong-smelling urine
- Pelvic or rectal pain
- Fever and nausea
Types of UTIs
There are four types of UTIs, depending on the area infected.
- Bladder infection (cystitis): This is the most common type of UTI. Symptoms include frequent urination, burning while urinating, urine that smells strong, cloudy or bloody urine, and lower abdominal pain.
- Kidney infection (Pyelonephritis): These usually begin in your bladder and travel up to your kidneys. Symptoms include frequent and painful urination, cloudy, bloody, dark, or bad-smelling urine, nausea and vomiting, chills, fever, and pain in your back, side, or groin.
- Urethritis: Inflammation of the urethra. Symptoms include frequent and painful urination, itch, and urethra discharge.
- Vaginitis: Inflammation or infection of the vagina. Symptoms include pain, itching, odor, redness, and vaginal discharge.

Ways to Help Prevent UTIs
- Urinate regularly and when the urge arises. Bacteria can grow when urine stays in the bladder too long.
- Drinking lots of fluid (water is best) to help flush bacteria out of the system.
- Urinate shortly after sex to help flush away bacteria.
- In women, wipe from front to back after using the toilet to prevent bacteria from entering into the urethra.
- Wear cotton underwear and loose-fitting clothes so air can keep the urethra dry.
- Use lubricated condoms without spermicide or a non-spermicidal lubricant during sex. A diaphragm or spermicide for birth control can promote bacteria growth and lead to UTIs.
- Wash the skin around your anus and genitals to prevent bacteria growth.
- Drink cranberry juice or use cranberry pills.
- Take showers instead of baths.
- Limit the amount of powders or sprays you use in your genital area.
Complications of UTIs
UTIs are common and treatable, but they can lead to other medical concerns:
- Repeat UTIs: Both men and women who have UTIs in the past run the risk of it developing again, especially if they don’t change their habits.Kidney damage: In rare cases, an untreated UTI can cause kidney damage, as can repeated kidney infections.
- Pregnancy risks: Premature births and low birth weights are among the complications pregnant women with UTIs can experience.
- Sepsis: An out-of-control release of chemicals by your body in an attempt to kill an infection, sepsis can cause organ damage and be life-threatening.
It’s important to seek treatment if you have a UTI or think you do.
Seeking treatment early is highly recommended as delayed diagnosis and treatment may lead to serious health risks.
Most UTIs can be treated by a primary care doctor or urgent care physician. Doctors typically prescribe antibiotics to treat UTIs, and symptoms clear up within a few days to a few weeks. Severe infections may be referred to a urologist (specializes in urinary disorders) or nephrologist (specializes in kidney disorders) for further treatment.
