What's a UTI
A urinary tract infection, or UTI, is an infection of any part of the urinary system. This includes the bladder (known as cystitis), urethra (known as urethritis) and kidneys (known as pyelonephritis).
UTIs are caused by bacteria, such as Escherichia coli (E. coli), travelling up the urethra and into the bladder. Bacteria can then multiply, resulting in an infection.
UTIs are extremely common, especially in women. This can be explained by the female anatomy. Women have a shorter urethra than men, which means that bacteria only have to travel a short distance from the gastrointestinal tract to reach the entrance to the urethra.
In fact, one in two women will experience at least one UTI in their lifetime.
Even though UTI symptoms can be uncomfortable, a short course of antibiotics can alleviate them and eliminate the infection in most cases.
Is a UTI dangerous?
Most urinary tract infections (UTIs) aren’t serious and can be treated effectively with antibiotics. However, some infections, if left untreated, can lead to a more serious health problem.
It is possible for a bladder infection to spread up the ureters to the kidneys, which can lead to kidney damage and scarring as well as a blood infection, but it’s not common. This condition is called pyelonephritis.
Pyelonephritis can cause chills, back pain, nausea, fever and vomiting. If this condition is suspected, your doctor will carry out urine, blood and/or imaging tests as well as prescribe antibiotics.
A more serious UTI can also travel to the bloodstream, causing sepsis. This is called urosepsis and can be life-threatening if untreated.
In short, when treated appropriately, an uncomplicated UTI should normally disappear within a few days. For this reason, you should get tested for a UTI if you have noticed any symptoms of infection.
Lower urinary tract infection
Most urinary tract infections (UTIs) involve the lower urinary tract. This includes the bladder and urethra.
An infection of the bladder is called cystitis, while an infection of the urethra is called urethritis.
Both types of UTI can be treated with antibiotics. Symptoms can be managed by taking painkillers and drinking plenty of fluids to reduce pain.
