A urinary tract infection (UTI) is one of the most common bacterial infections, affecting any part of the urinary system — the kidneys, ureters, bladder or urethra. Most are easily treated and clear up completely with the right antibiotics. Dr. Anish Gupta assesses and treats simple, recurrent and complicated UTIs across Delhi NCR, and looks for any underlying cause when infections keep coming back.
What is a urinary tract infection?
The urinary tract is the system that makes, stores and passes urine out of the body. It is made up of the kidneys, the ureters (the tubes draining each kidney), the bladder and the urethra. A UTI develops when bacteria — most often from the bowel — enter this system and multiply. Lower UTIs affect the bladder (cystitis) or urethra (urethritis) and are the most common; an upper UTI reaches the kidney (pyelonephritis) and is more serious.
UTIs are far more common in women than in men because the female urethra is shorter. When an infection occurs in a man, a child or during pregnancy, it deserves closer assessment, as it is more likely to point to an underlying problem.
Symptoms
The symptoms depend on which part of the urinary tract is affected. Common signs of a lower UTI include:
- A burning sensation or pain when passing urine
- Needing to urinate more often and more urgently
- Passing only small amounts of urine at a time
- Cloudy, strong-smelling or blood-tinged urine
- Discomfort or pressure in the lower abdomen
An upper UTI affecting the kidney can also cause pain in the side or back (flank), high temperature, chills, nausea and feeling generally unwell. If you notice blood in your urine, this should always be checked even after the infection settles.
Causes and risk factors
Most UTIs are caused by bacteria entering through the urethra. Several factors make them more likely:
- Being female, or going through the menopause
- Not emptying the bladder fully — for example due to an enlarged prostate in men
- Kidney or bladder stones that trap bacteria
- Diabetes or a weakened immune system
- A urinary catheter or recent urinary procedure
- Dehydration and infrequent urination
When to see a urologist
See a urologist if you have repeated UTIs, blood in your urine, fever with back pain, or if a UTI occurs in a man, a child or during pregnancy. Symptoms that are getting worse, an inability to keep fluids down, or being unable to pass urine all need prompt medical attention, as an untreated infection can ascend to the kidneys and, rarely, lead to serious complications such as blood poisoning. Recurrent infections can be a sign of a treatable underlying cause, so they should never simply be tolerated.
How it is diagnosed
Diagnosis starts with your symptoms and a simple urine test. Dr. Anish Gupta may then advise:
- A urine dipstick test to look for signs of infection
- A urine culture to identify the exact bacteria and the antibiotics that will work best
- Blood tests if an upper UTI or kidney involvement is suspected
- An ultrasound scan to check the kidneys and how well the bladder empties
- A cystoscopy to look inside the bladder when infections keep returning
Treatment options
Treatment is matched to how severe the infection is and whether there is an underlying cause.
Self-care and simple measures
Drinking plenty of fluids helps flush bacteria from the urinary tract, and simple pain relief such as paracetamol eases discomfort. Passing urine regularly and not holding on also helps. Anti-inflammatory painkillers are best avoided if a kidney infection is suspected.
Antibiotics
A short, targeted course of antibiotics clears most simple lower UTIs, often within a few days. Complicated or recurrent infections may need a longer course guided by a urine culture, so the right antibiotic is chosen from the start.
Treating recurrent and complicated UTIs
When infections keep returning, the aim is to find and treat the cause — such as stones, incomplete bladder emptying or an enlarged prostate. Options may include preventive measures, low-dose preventive antibiotics for a period, and treating the underlying problem. Severe or upper UTIs sometimes need treatment in hospital with fluids and antibiotics given through a drip. You can read more in our overview of urinary tract infections.

Frequently asked questions
How long does a urinary tract infection take to clear up?
A simple lower UTI usually starts to improve within a day or two of starting the right antibiotic, and most clear within a few days. Drinking plenty of fluids helps. If symptoms are not settling, a urine culture may be needed to choose a better-targeted antibiotic.
Why do I keep getting UTIs?
Recurrent infections can be linked to incomplete bladder emptying, stones, the menopause, diabetes or, in men, an enlarged prostate. Because a treatable cause is often present, repeated UTIs should be assessed by a urologist rather than simply treated again each time.
Can a UTI go away on its own?
Very mild bladder infections occasionally settle with plenty of fluids, but this is not reliable and the infection can worsen or spread to the kidneys. It is safer to have symptoms assessed and treated, especially in men, children, pregnant women or anyone with fever or back pain.
Is a UTI serious?
Most UTIs are not dangerous when treated promptly. However, an untreated infection can travel up to the kidneys and, rarely, cause serious illness. Fever, back or side pain, vomiting or blood in the urine are signs that you should seek medical care without delay.
Every treatment plan starts with a proper assessment, so you only get the care your condition actually needs — and if the honest answer is that you don't need a procedure, you'll hear that too.
