While the symptoms and causes of UTIs have been extensively discussed, there’s one aspect that often remains shrouded in mystery: the distinct UTI smell. 

Individuals often complain about their urine smelling weird when they contract a UTI.

In some cases, women also find a change in the smell of their vaginal discharge as a result of a  Urinary Tract Infection. 

Hence, it becomes important to understand what causes UTI smell and how to get rid of it.

This article talks about them, exploring why they occur, their potential implications, and how one can effectively manage and address this concern.

Do UTI smell

One of the distinct characteristics of a UTI is the change in the odor of urine. 

This change in smell is primarily attributed to the bacteria present within the urinary tract.

The bacteria that causes the UTI triggers an inflammatory response. 

While it is important to note that not all UTIs manifest with a noticeable odor, for some individuals, this change can be rather distinct. 

The smell is often described as strong, pungent, ammonia-like, and sometimes slightly sweet. 

This unique odor is the result of the body’s immune system responding to the bacterial invasion.

Women are more vulnerable to UTIs due to their shorter urethra.

UTIs are predominantly caused by bacteria, such as Escherichia coli (E. coli).

This bacteria can enter the urinary tract through the urethra and multiply in the bladder. 

The resulting infection prompts the body to release white blood cells to combat the bacterial intrusion, leading to inflammation. 

This immune response and the breakdown of waste products contribute to the altered smell of urine. 

The presence of mucus, bacteria, and white blood cells in urine are, hence, indicators of Urinary Tract Infections.

Another reason why UTI pee smells could be the antibiotics that are given to treat the infection.

These antibiotics are made from mold, which can make your urine smell yeasty.

Can UTI cause smelly discharge

While UTIs primarily affect the urinary system, they can sometimes lead to changes in vaginal discharge, which might result in an unusual odor. 

It is important to note that UTIs typically do not directly cause vaginal discharge.

But, the infection’s proximity to the urethra and vagina can create an environment that encourages the growth of harmful bacteria. 

This bacterial overgrowth might contribute to changes in vaginal discharge, including its odor.

The presence of bacteria from the UTI, along with the potential disruption of the natural balance of vaginal flora, can lead to an alteration in vaginal discharge. 

This might result in a stronger or more noticeable odor than usual. 

It’s important to remember that vaginal discharge can vary throughout the menstrual cycle, and some odor is normal. 

However, if the odor becomes particularly strong, foul-smelling, or is accompanied by other symptoms such as itching, irritation, or pain, it’s advisable to seek medical attention.

How to get rid of UTI smell

While the smell associated with UTIs can be discomforting, it’s important to remember that it’s a temporary symptom that tends to subside as the infection is treated.


Antibiotics prescribed by your doctor can help eradicate the bacteria causing the infection and subsequently alleviate the associated odor.

It is crucial to complete the full course of antibiotics as prescribed, even if the smell improves before the medication is finished.

Stay hydrated

Drinking plenty of water helps flush out bacteria and waste products from the urinary tract. 

Adequate hydration can also dilute the urine, which may help reduce the intensity of the smell.

Avoid certain foods

Some foods, such as strong-smelling spices and asparagus, can temporarily affect the odor of urine. 

Limiting these foods might help reduce the intensity of the smell.

Personal hygiene

Proper hygiene is extremely essential to prevent the spread of bacteria and reduce the UTI smell. 

Keep the genital area clean with mild, unscented soaps and water. 

Avoid using strongly scented products that could irritate the area.

Some individuals find that cranberry juice or cranberry supplements can help support urinary tract health. 

Cranberries contain compounds that may inhibit the adherence of bacteria to the urinary tract lining.

Additionally, probiotic supplements or foods containing beneficial bacteria can help restore the natural balance of flora in the urinary and vaginal areas.

Both of them work to treat UTIs, which eventually helps get rid of the UTI smell.

Consult a healthcare professional

If the smell persists or worsens despite taking these measures, it’s important to consult a healthcare professional. 

They can ensure the infection is properly treated and rule out any complications.

Do not take any medication without a doctor’s consultation. Unsupervised treatment might lead to unwanted adverse effects.


UTI is known to cause smelly urine and vaginal discharge in some of the affected individuals.

They are typically strong and pungent.

This distinct UTI smell that accompanies the infection can be a useful sign of the body’s immune system’s reaction to bacterial invasion.

Proper hygiene, hydration, and timely medical attention are pivotal in managing both the UTI and its associated smell. 

By understanding the connection between UTI and its peculiar smell, individuals can take charge of their health and well-being, ensuring that they seek the necessary care when needed.

Does UTI have a foul smell?

Yes, a UTI may result in distinct and sometimes foul-smelling urine due to the body’s immune response and the presence of bacteria. However, not everyone with a UTI will experience a significant change in urine smell. Treating the infection, however, relieves the odor as well.
