What Are The Risks of Leaving UTI Untreated?

Urinary tract infections (UTIs) are one of the most common infections worldwide. Although they aren’t generally a medical emergency, they can be very painful and make it difficult to go about your usual daily routine. 

UTIs occur when bacteria find their way into the urethra — the tube that connects to the bladder and moves urine out of the body — and cause an infection along the urinary tract. Since women have a shorter urethra than men, they’re more susceptible to UTIs. In fact, up to 70% of women will experience a UTI in their lifetime, and Canadian women make about 500,000 doctor visits per year for a UTI.

Untreated UTIs can become more severe and lead to several serious health consequences. Read on to learn how a UTI is diagnosed and treated — and the potential risks of ignoring it and hoping it’ll go away on its own.

How are UTIs Diagnosed and Treated?

Common symptoms of a urinary tract infection include frequent and painful urination, discomfort in the pelvic area, and cloudy or foul-smelling urine. Since the symptoms of a UTI can be mistaken for other conditions, like bladder infections,  premenstrual syndrome, or ailments associated with menopause or advanced age, UTIs may be diagnosed through a urine sample if the diagnosis is unclear or if the UTI symptoms don’t improve despite a first course of UTI treatment. Samples can also be used to differentiate between kidney stones and STI testing.  If UTI-causing microbes are present in the urine sample, your doctor will prescribe an antibiotic.

What is an Untreated UTI?

An untreated urinary tract infection (UTI) occurs when bacteria in the urinary tract multiply without being addressed, potentially leading to more serious health issues. UTI, left untreated, can progress from the bladder to the kidneys, leading to a condition called pyelonephritis, which can cause significant kidney damage. In severe cases, the infection can enter the bloodstream, causing a life-threatening condition known as urosepsis. Common symptoms of an untreated UTI include pain or burning during urination, frequent urge to urinate, cloudy or strong-smelling urine, and lower abdominal pain. Prompt antibiotic treatment is typically effective in eliminating a UTI, preventing complications, and restoring urinary health.

Consequences of Leaving a UTI Untreated

While mild urinary tract infections can clear up within 24 to 48 hours, they generally require antibiotic treatment. To ensure the infection completely clears up, it’s important to finish the full course of antibiotics, even if you notice signs your UTI is going away before you’ve finished the prescription. If a UTI is left untreated, it can lead to more serious health issues, including the following:

1. Increased pain and discomfort

As microbes take hold in your urinary system, they cause inflammation in the tissues, leading to increased pain and discomfort. As with any infection, your body needs plenty of rest for optimal recovery, but the increased pain and discomfort can interfere with sleep, work, exercise, and your lifestyle, making it even harder for your body to fight the infection and for you to feel on track.

2. Kidney infection (pyelonephritis)

An untreated urine infection can move further up the urinary tract to the kidneys, causing a kidney infection. A kidney infection can cause permanent damage, including renal papillary necrosis, a condition that decreases kidney function and can lead to kidney failure.

3. Recurrent infections

Untreated UTIs often lead to recurrent infections since the bacteria never really goes away — it just becomes less prolific, waiting for the right conditions to regain its numbers. Recurrent UTIs are defined as two or more infections within six months or three or more within a year.

4. Sepsis

Sepsis, or urosepsis, is a life-threatening infection that occurs when an untreated UTI travels to the kidneys and the body’s defence system turns on itself, attacking tissues and organs. Treatment for sepsis requires hospitalization, intravenous (IV) antibiotics, and monitoring for organ failure and septic shock. 

5. Bladder damage

The inflammation caused by a UTI can damage the protective layer of cells that line the bladder, leading to permanent bladder damage. In some cases, this chronic damage can be a contributing factor in bladder cancer.

6. Pregnancy complications

UTIs during pregnancy can impact fetal health and cause low birth weight or premature delivery. They may also increase the risk of high blood pressure and anemia.

7. Urethral narrowing in men

Over time, untreated and recurring UTIs can scar the urethra in men. The built-up scar tissue narrows the walls, making it more difficult to pass urine. This can cause a build-up of microbes in the bladder, increasing the frequency of UTIs and the risk for prostate or kidney infections and permanent damage.

How Long Can You Have a UTI Without Knowing It

A urinary tract infection (UTI) can sometimes go unnoticed, especially when symptoms are mild or absent. This makes many wonder, “How long can you have a UTI without knowing it?” While every case is unique, some UTIs can linger undetected for days or weeks. Infections that go unnoticed may eventually worsen, especially if left untreated for an extended period.

For mild cases, symptoms might be subtle or easily mistaken for other conditions, so a UTI can go untreated if someone does not recognize the early signs. In some cases, low-grade infections may not cause immediate discomfort, allowing the bacteria to multiply quietly in the urinary tract. However, the bacteria can spread over time, causing more noticeable symptoms and potentially progressing to the kidneys.

How to Prevent UTIs

UTIs can lead to serious complications, especially in pregnant women, seniors, people with memory issues, and those with recurrent UTIs. Here are a few things anyone can do to help reduce the risk of a urinary tract infection:

• Stay hydrated: Drinking ample water throughout the day can help prevent UTIs by continually flushing the urinary system and supporting immune function.
• Practice good hygiene: Always wipe from front to back after using the toilet, and wash your hands thoroughly. 
• Use the washroom before and after sex: Urinating before and after sex can help flush away any microbes that may have migrated to the urethra.
• Empty your bladder when you urinate: Try to completely empty your bladder every time you go, since small amounts of urine left behind create a perfect environment for microbial growth.

When to Call Your Doctor About a UTI

It’s wise to seek medical care at the first sign of a urinary tract infection (UTI). The sooner it’s diagnosed and treatment begins, the less pain and discomfort you’ll likely experience — and the lower your risk of complications associated with an untreated UTI.

Conclusion

Taking proactive steps to prevent and address UTIs can significantly improve your overall health and comfort. Remember, early treatment can help avoid complications that may occur if a urine infection is left untreated. If you suspect you have a UTI, do not hesitate to reach out to a healthcare provider for guidance. Your health matters, and staying informed is the first step in taking control.
