Understanding Urinary Tract Infection: Causes, Symptoms, and Treatment

A urinary tract infection (UTI) happens when bacteria affect any part of your urinary system, from the bladder to the kidneys. UTIs mostly affect the lower urinary tract (bladder and urethra) compared to the upper urinary tract (kidneys and ureters). Even though upper urinary tract infections are rare, they are more severe.

Statistics reveal that about 60% of women and 12% of men will get at least one UTI during their lifetime. Though UTIs are usually mild infections they can become serious, and understanding their causes and symptoms will help you identify them and seek treatment for them earlier, avoiding further complications.

Causes and Risk Factors of UTI

Contributing factors to UTIs include:

  • Kidney stones
  • Age (elderly people are more vulnerable)
  • Enlarged prostate gland
  • Some types of cancer
  • Reduced mobility due to prolonged bed rest or post-surgery
  • Diabetes
  • Abnormal congenital urinary structures

Other risk factors of a UTI are:

  • Weakened immune system
  • A recent urinary tract surgery
  • A previous UTI
  • Prolonged use of a catheter
  • Difficulty emptying the bladder (holding urine for a long period can help bacteria grow in the bladder, causing a UTI)

What Are the Symptoms of UTIs?

UTI symptoms vary depending on which part of the urinary tract is infected.

Symptoms of a Lower Tract UTI

  • Bloody urine
  • Burning with urination
  • Increased frequency and urge to urinate
  • Pelvic pain or rectal pain

Symptoms of an Upper Tract UTI

  • Vomiting
  • Pain and tenderness in the sides and upper back
  • Nausea
  • Chills
  • Fever

Upper tract UTI symptoms remain similar for men and women. Nevertheless, a lower tract UTI may cause pelvic pain in women and rectal pain in men, besides other signs.

Are Females More Prone to UTIs Than Males?

Women are 30 times more likely to develop UTIs than men. Besides, 4 in 10 women with a UTI will develop another within six months.

Here is what makes women more susceptible to UTIs than men:

#1: Anatomy

Women's urethras are shorter than men’s, which makes it easier for the bacteria to enter the bladder. Also, the urethral opening is closer to the rectum, where bacteria reside, increasing the chances of UTIs.

#2: Menstrual Health

Women's estrogen circulation will usually decrease post-menopause, causing changes in the urinary tract, thus making them vulnerable to infection.

#3: Sexual Activity and Contraception

Sexually active women and those using certain types of birth control, such as diaphragms and spermicidal agents, are at higher risk of getting UTIs.

What Are the Reasons for Recurrent UTIs in Women?

Women may get recurrent UTIs due to:

#1: Infection of the Urethra (Urethritis)

Urethritis occurs due to sexually transmitted infections (gonorrhea, chlamydia, herpes, and mycoplasma) or when gastrointestinal bacteria spread from the anus to the urethra.

#2: Infection of the Bladder (Cystitis)

Cystitis is usually caused by intercourse (even if you are not sexually active) and Escherichia coli (E. coli) bacteria commonly found in the gastrointestinal tract. However, sometimes, other bacteria can also cause it.

Tips to Prevent a Urinary Tract Infection

#1: Drink Plenty of Fluids

Water and other fluids help to keep your bladder tissue healthy and hydrated. It also lowers the concentration of bacteria in the bladder by diluting your urine. Sometimes, fluids can help clear an infection. Ensure to drink at least 1.5 liters of fluids daily to prevent infections.

#2: Regularly Empty Your Bladder

Urine contains waste products, so regularly emptying your bladder ensures that those wastes won’t stay in your bladder for longer periods, which could otherwise encourage bacteria to grow and multiply, causing an infection. Consider emptying your bladder 4-8 times per day.

#3: Take Cranberry Supplements

Taking cranberry supplements could be helpful in preventing UTIs, by interfering with bacteria attaching to the bladder sidewalls. Instead of cranberry juice, you can try a concentrated over-the-counter cranberry supplement, as it provides more benefits while eliminating extra sugar found in juice.

#4: Avoid Using Irritating Feminine Products

Using products such as douches, powders, and deodorant sprays in your genital area can irritate the urethra, resulting in an infection.
