If a UTI doesn't go away after antibiotics, it could mean the bacteria are antibiotic-resistant, the infection is more complex (like a kidney infection), the wrong antibiotic was used, you have an underlying condition mimicking a UTI, or you stopped medication too soon, requiring further testing (urine culture, imaging) and potentially a longer or different antibiotic course or investigation for other issues like kidney stones, interstitial cystitis, or STIs. Ignoring persistent symptoms risks severe complications like sepsis, so contacting your doctor for a follow-up is crucial.
If your UTI comes back after treatment, or you have 2 UTIs in 6 months (or 3 within 12 months), you'll need to see a GP. They may: prescribe a different antibiotic or prescribe a low-dose antibiotic to take for up to 6 months.
You may need further testing or a different treatment. A UTI may start as a bladder infection (cystitis) and could worsen into a more serious kidney infection (pyelonephritis) or urosepsis (a serious infection throughout your body) that is a medical emergency. Contact your doctor.
Could It Be Something Else?
Causes of Recurrent UTIs
A child who doesn't drink enough fluid may not make enough urine to flush away bacteria. This often goes hand in hand with bowel dysfunction such as constipation. These problems increase the risk of UTI.
In order to treat recurring UTIs, a urologist typically makes an attempt to identify the underlying reasons why this is happening. Testing may involve a cystoscopy, a CT scan of the urinary tract, and a urine culture.
In children aged 3 months or over, UTI should be suspected if signs and symptoms are present, including fever, frequency, dysuria, abdominal pain, vomiting, poor feeding, dysfunctional voiding, or changes to continence.
However, if the infection is left unchecked, it can spread up the ureters to your kidneys, leading to a kidney infection. On average, it can take between a few days to a week for a UTI to turn into a kidney infection if left untreated.
Chlamydia, gonorrhoea, and trichomoniasis may all cause burning when urinating and increased frequency. Unlike UTIs, STIs might also cause unusual discharge, itching, or pain during sexual activity. Because the symptoms overlap, it's easy to confuse one for the other.
Foods to Avoid With Urinary Tract Infections (UTIs)
About 50-60% of patients with recurring UTIs require multiple rounds of antibiotics. Fortunately, medications such as nitrofurantoin and trimethoprim-sulfamethoxazole are often effective, with success rates around 90-93%.
Daily Antibiotic Regimen
Low-dose antibiotics may be prescribed for 6–12 months to help keep urine clear of infection. This treatment allows the bladder time to heal, so it is better able to prevent infection on its own in the future.
But sometimes other bacteria are the cause. Infection of the urethra. This type of UTI can happen when GI bacteria spread from the bowel to the urinary tract. An infection of the urethra also can be caused by sexually transmitted infections, such as herpes, gonorrhea, chlamydia and mycoplasma.
Simple (Uncomplicated) UTI: Most bladder infections in healthy women are “simple.” They usually clear up with a short course of antibiotics—usually 3 to 7 days. Pain and urgency often get better within a day or two. Finish the full antibiotic course even if you feel better. Drink plenty of fluids while you recover.
Embedded or Biofilm infection
However, under the right circumstances, these bacteria can stick to the bladder lining, and form a networked community, shielded by a protective slimy material. This slimy material protects the bacteria from antibiotics, as well as shielding it from the body's natural defences.
A UTI causes inflammation in the lining of your urinary tract. The inflammation may cause the following problems: Pain in your flank, abdomen, pelvic area or lower back. Pressure in the lower part of your pelvis.
Interstitial cystitis (IC)/bladder pain syndrome (BPS) is a chronic bladder health issue. It is a feeling of pain and pressure in the bladder area. Along with this pain are lower urinary tract symptoms which have lasted for more than 6 weeks, without having an infection or other clear causes.
Another main difference between the two is that cystitis is located in the bladder only. A urinary tract infection presents itself in any part of the urinary system. This is what causes the most significant distinction of not being able to say that these two conditions are the same.
Drinking lots of water, and emptying your bladder when you need to, will help you flush harmful bacteria from your system. You may be hesitant to drink water due to the burning sensation you may have when peeing, but trust us on this – getting in your recommended 8 glasses a day will do you a world of good.
A lower UTI and a kidney infection can have similar symptoms, but a kidney infection is more likely to suddenly make you feel sick, give you a fever or cause pain in your lower back or side.
If the infection spreads to your kidneys, symptoms may include: Chills and shaking or night sweats. Fatigue and a general ill feeling. Fever above 101°F (38.3°C)
In mild cases, you might deal with discomfort for about a week or two, but this depends on your immune system's ability to fight off the infection. In other situations, untreated infections can persist for weeks, spreading to the kidneys and causing more severe health issues like pyelonephritis.
A UTI becomes an emergency when it causes serious symptoms like high fever, confusion, vomiting, or severe back or side pain. These may be signs the infection has spread to the kidneys or bloodstream. Call 911 or go to the ER if you can't stand, think clearly, or breathe easily.
Urinary tract infections (UTIs) may also cause an abnormal appearance of the urine such as cloudiness, brown or red color, or an unusual smell.
