Urinary Tract Infection

What is Urinary Tract Infection?

A urinary tract infection (UTI) is an infection that occurs in any part of the urinary system which includes the kidneys, ureters, bladder and urethra. In most cases, these infections are seen in the lower urinary tract i.e. the bladder and the urethra. If left untreated, UTI can spread to the kidneys and cause serious damage.

Symptoms

Symptoms of urinary tract infections include:

  • Frequent urination
  • Burning sensation when urination

Causes

Urinary tract infections typically occur when bacteria enter into the urinary tract through the urethra and begin to multiply in number. The most common causes of UTIs include.

  • Infection of the bladder or cystitis: This disease is usually caused by Escherichia coli (E. coli), a type of bacteria commonly found in the gastrointestinal (GI) tract.
  • Infection of the urethra or urethritis: This type of UTI is caused when GI bacteria enter the urethra. Sexually transmitted infections, such as herpes, gonorrhea, chlamydia and mycoplasma, may also cause urethritis.

Risks

The following factors increase the risk of Urinary tract infections in people:

  • Sex: Females are more prone to UTIs as compared to men as a woman has a shorter urethra than a man does which shortens the distance that bacteria must travel to reach the bladder
  • Use of a catheter: People who are unable to urinate on their own and use a tube or a catheter to urinate have an increased risk of UTIs.
  • Sexual activity: People who are sexually active women tend to have more UTIs than people who aren't sexually active.
  • Certain birth control measures: Use of diaphragms and spermicidal agents for birth control may increase the risk of UTIs in women.
  • Menopause: Women who have had menopause experience a decline in circulating estrogen that makes them more vulnerable to infection.
  • Urinary tract abnormalities: Certain urinary tract abnormalities that restrict the urine within the body or cause it to flow back up into the urethra increase the risk of UTIs.
  • Blockages in the urinary tract: Kidney stones or an enlarged prostate can create blockages in the urinary tract and increase the risk of UTIs.

    Treatment through medications is used to treat simple as well frequent urinary infections. If the patient has simple urinary infections, the doctor may recommend drugs like antibiotics, analgesics, Trimethoprim, Fosfomycin, Nitrofurantoin and Ciprofloxacin to relieve the symptoms. However, if the infections are frequent, the doctor recommends low-dose antibiotics or Vaginal estrogen therapy if the patient is postmenopausal.
