For those of you that aren't familiar with the anatomy of the human body, the kidneys are the organs that make the urine, and it's the bladder that stores the urine until you're ready to excrete it. Since these two organs are very closely linked, an infection in one can very easily be passed up or down to the other!

That's why today, we thought it may be useful to touch on urinary tract infections (UTIs), as an important addition to London Doctors Clinic's Kidney Health week. UTI is an umbrella term for a group of infections which affect the bladder, kidneys and the tubes connecting them.


UTI Symptoms 

The symptoms of UTIs differ depending on which part of the urinary tract is affected.

If the infection is in the bladder (known as cystitis) or the urethra (the tube that takes urine out of the body), these are ‘lower’ UTIs.

Symptoms of lower UTI include:

  • A need to pee more often than usual 
  • Pain or burning when peeing
  • Sudden urges to pee
  • Feeling like you can’t fully empty your bladder
  • Pain in the lower part of your tummy
  • Cloudy, foul-smelling or bloody urine
  • Generally feeling unwell, achy or tired

Infections of the kidneys or the ureters (the tubes connecting the bladder and kidneys) are upper UTIs.

The symptoms of upper UTI include:

  • High temperature (38°C) or above
  • Pain in your side or back
  • Shivering/ chills
  • Feeling nauseous/ being sick
  • Confusion
  • Agitation/restlessness



Symptoms of upper UTIs include a pain in your side


Lower UTIs are common and are rarely very serious. In many cases, lower UTIs are self-limiting, meaning they can resolve by themselves, without treatment. Upper UTIs, however, are more serious and will always require treatment. If left untreated, an upper urinary tract infection can result in more widespread infection or damage to the kidneys.


UTI Causes 

Urinary tract infections are generally caused by bacteria (usually gut bacteria) infecting the urinary tract.

Women are at increased risk of a UTI compared to men. This is generally thought to be because the urethra is shorter in woman and closer to the back passage than in men. This transfer bacteria from the gut to the urinary tract may occur during sex or when wiping after going to the toilet.

You may also be at increased risk of getting a UTI as a result of having the following:

  • Conditions where there is an obstruction in the urinary tract such as a kidney stone
  • Diabetes
  • Using condoms or diaphragms coated in spermicide
  • Difficulty emptying your bladder fully
  • A weak immune system
  • A urinary catheter (a plastic tube in your bladder which helps drain urine)
  • An enlarged prostate (in men)


UTI Treatment

UTI treatment generally involves a short course of antibiotics. This is generally a 3-day course for women, or a longer course for men, pregnant women, or anyone with more serious symptoms.

Although symptoms may subside before the course of antibiotics is finished, it is important to make sure that you finish the full course prescribed, to you to ensure that the infection is completely treated.

If you're struggling with pain from this UTI, over the counter painkillers such as paracetamol can help. Often people find that drinking lots of water can help with symptoms too.

Of course, if your symptoms get worse, don’t improve or return despite treatment, make sure to come back to the GP as they may need to prescribe you a different antibiotic.


UTI Prevention

Some people get frequent UTIs which can be painful and frustrating. There are several things you can try which may reduce the risk of a UTI, although their effectiveness is unclear.

Measures to reduce your risk of UTI could include:

  • Avoiding perfumed soaps and bubble baths
  • Showering instead of having a bath
  • Not holding you bladder (i.e. going to the toilet as soon as you need to pee!)
  • Staying well hydrated
  • Wiping your bottom from front to back
  • Peeing after sex
  • Avoiding condoms/ diaphragms with spermicidal lubricant (other methods of contraception may be better for you)
  • Wearing cotton underwear and avoiding tight clothing 


Although some sources state that drinking cranberry juice or probiotics might help in preventing urinary tract infections, there is no clear evidence in favour of this.

If you are still suffering with repeated UTIs despite making these changes, it may be that you need further treatment, so do make sure to return to your GP.
