What percentage of hospitalizations in the elderly are caused by UTIs? Stats + tips for how to prevent your loved one from becoming one are below.

An Almost Deadly Summer

Last summer, my mother and I traveled to California for my cousin's wedding. A few days later, she was in the Emergency Room (ER), getting a dose of IV antibiotics for a UTI, followed by a hospital stay for sepsis — an often fatal response to infection. Just like that, I could have gone from full-time caregiver to funeral planner. Thankfully, I only went from a visitor sleeping on the hospital room vinyl loveseat to an administrator of IV antibiotics at home. YES! The doctor put her on a two-week course of IV antibiotics, and I was taught to administer them once we were discharged. The situation was a very close call and further complicated by the IV administration post-discharge, so I hope the lessons I learned below will help prevent you from going through the same.

If you are curious about my mom today. She's doing well. Thankfully, she recovered and reclaimed her role as backseat driver and unabashed matchmaker. She insists on trying to find me a husband everywhere I take her... everywhere.

Why You Need to Act Fast If You Suspect a UTI

  • UTIs are responsible for around 25% of all geriatric hospitalizations, according to a study by C. Dutta published by the National Institutes of Health (NIH).

  • 33% of functionally dependent geriatric patients with UTIs died during their hospital stay, according to a study conducted by the Annals of Translational Medicine


While prevention is ideal, catching and treating the infection immediately is critical. In my experience, this applies to any illness in the elderly, particularly when multiple health issues are present.

Whether the body is too frail to fight an infection or there are pre-existing conditions, the UTI can become the tipping point between life and death.

Why Common UTI Symptoms Are Hard to Spot in the Elderly

Unlike respiratory illnesses, which are accompanied by an audible cough or visible runny nose (symptoms easy for a caregiver to spot), common UTI symptoms are experienced privately and require: 1) your loved one to actually experience symptoms and recognize something is wrong 2) know to give you a heads up and 3) remember to give you the heads up These are things we can take for granted, but can be a huge challenge as we age. Especially since an elderly person might not experience the classic UTI symptoms seen in the general population.

  • Feel the burn? Probably not.

    As we age, we might not experience the burning sensation often associated with a UTI because we can lose our sensation "down there" (a medical professional shared that tidbit with me), so the chances that your loved one will "feel the burn" are slim.

  • Can you identify the odor? I hope so!

    Another tell-tale symptom of a UTI, foul-smelling urine, might be present, but your loved one needs to have the ability to recognize the unusual odor and communicate that with you, or you need to be close enough to catch a whiff.


Meanwhile, the undetected UTI can continue to fester. The good news is that, through a stroke of divine genius, visible UTI symptoms do exist in the elderly; they are just atypical.

UTI Symptoms in the Elderly

I'm going to share the official symptoms of UTIs in the elderly, and then I'll share my experiences. According to an NIH study, "UTI manifests more commonly for this age group as delirium or confusion in the absence of a fever."

Other symptoms include:

  • hypotension (low blood pressure),

  • tachycardia (faster than normal heart rate)

  • urinary incontinence

  • poor appetite

  • drowsiness

  • frequent falls

How to Spot a UTI in Your Elderly Loved One, A Caregiver's Perspective

As a caregiver, I have observed that any behavior that makes you go "huh..." or "hmmm, that was weird..." can be a sign of a UTI. The situation reminds me of how a laptop behaves before it crashes - the buttons aren't responsive, funny messages pop up... In addition, UTI symptoms are unique to the individual. Despite my mother's dementia, she did not display delirium or confusion. She was, however, very fatigued, much more than normal, and her heart rate was lower than usual. I have categorized UTI symptoms into two categories: atypical and exaggerated.

  • Atypical (or peculiar) behavior: If you notice any deviation from standard behavior, it could be a symptom of a UTI in an elderly person. For example, I have heard of people fainting and even taking their clothes off in situations where that would be a bizarre choice.

  • Exaggerated behavior: If your loved one is exhibiting a more exaggerated version of existing behavior, that can also be a sign of a UTI. For example, my mother typically experiences fatigue and takes naps, but she was "napping super hard" and walking more slowly than her typical amount of slow.

Pro Tip: Know your loved one's baseline behavior. If you spot any deviations, seek medical attention. If it's not a UTI, it could be something else...

When to Seek Emergency Care for a UTI in the Elderly

This is my perspective as a caregiver, but if you are dealing with the following symptoms, skip the urgent care and head straight to the ER:

  • Sudden confusion, agitation, or delirium

  • Fever above 103°F or, conversely, an unusually low body temperature

  • Rapid heart rate or dangerously low blood pressure

  • Inability to keep fluids down

  • Extreme fatigue or unresponsiveness (such as fainting)

  • Any behavior that is out of the ordinary

    In the elderly, a UTI can progress to sepsis — a potentially fatal infection response — in no time. When in doubt, err on the side of the ER.

Hey UTI, Mind Staying in Your Own Lane? Thank You Kindly.

In youth (or relative youth), we can take a lot for granted — like the idea that a respiratory illness is confined to the respiratory system — a sometimes novel concept for an elderly person.

In a frail or compromised elderly person, such as one with a heart condition or dementia, or both, the whole body can jump in...imagine a flashing "red alert" sign and a siren going off - the heart, the brain, the kidneys... an assortment of vital body organs are now involved in what could have been an isolated incident. In my mother's case, her heart is where the UTI symptoms showed up the loudest, and where I saw the most "malfunction". It makes sense. At this time, my mom had an excruciatingly narrow aortic valve. So, keep your loved one's health conditions in mind. Atypical behavior in one of those already compromised areas could be a sign of infection.

After a couple of close calls, including this one, I realized I had to prioritize immediate care for my mom, even for what might seem like a minor issue - UTI, respiratory illness, etc. Depending on the condition of your loved one, anything can quickly snowball into a hospitalization or worse. Unfortunately, health issues don't always fit neatly into your schedule, and they don't take weekends, birthdays, and holidays off (quite inconsiderate, if I do say so).

What Causes a UTI in the Elderly

According to a conversation with one of my mom's doctors, poor hygiene "down there" is the most common cause of UTIs in the elderly; he specifically mentioned fecal matter as a very common culprit. Fecal matter finds its way into the urethra, and a UTI is born. This is supported by research published in US Pharmacist, which identifies poor hygiene and urethral contamination with fecal bacteria as one of the more common causes of UTIs in the geriatric population, particularly in those with dementia. Public toilets, weakened immune systems, incomplete bladder emptying, and activities you might not want to think about your elderly loved one engaging in are other causes. If you want more on causes, you can check out this study published by NIH.

UTI Prevention in the Elderly

This topic is very much TMI and yet also very critical. UTI prevention is all about keeping bacteria out of the urethra, so cleanliness down there is key, and so is proper wiping.

One must wipe from front to back, not back to front. Wiping from back to front can drag fecal matter from the anus into the urethra.

This tidbit is validated in a few highly reputable places - Harvard Health mentions the front-to-back wiping as the first step in UTI prevention for older women, and according to clinical guidelines published by the National Institutes of Health, most urinary infections come from bacteria that live around the rectum and anus.

I have wet wipes on hand in the bathroom, but I have to chase after my mom to use them. I have also considered replacing the toilet seat in her bathroom with a bidet toilet seat. I will likely have to chase after her for that too, but I think it will be worth it. Have we exhausted the topic of poop for the moment? I hope so!

Add-ons: After my mother first had her stroke, she was getting UTIs frequently. This was before her health was compromised, as it is now. One nurse told me that D-Mannose can help keep bacteria from "sticking" to the urinary tract. Cranberry extract was another tip for preventing UTIs. That said, if you are considering any supplements, including these, or even vitamins, always consult a doctor before taking them or giving them to anyone. The elderly can be frail, some supplements can decrease the effectiveness of medications...and you don't want to go from bad to worse.

By the way, cranberry products are mentioned in an NIH review of UTI treatment options, though evidence for their efficacy "continues to evolve." I look at these as "for good measure" add-ons to the deal breaker - great hygiene. But again, always consult a medical professional before taking or giving.

Frequently Asked Questions about UTIs in the Elderly

Can a UTI cause confusion in an elderly person?

Yes. Sudden confusion or delirium — even without a fever — is one of the most common signs of a UTI in older adults. According to a systematic review published by the NIH (Dutta, 2022), UTI in the elderly manifests most commonly as delirium or confusion in the absence of a fever. Unlike younger people who typically experience burning and urgency, elderly patients often present with behavioral and cognitive changes first. These are "official" answers. Despite my mom's dementia, she was not more confused.

What are the signs of a UTI in an elderly woman?

Common signs include sudden confusion, unusual fatigue, low blood pressure, rapid heart rate, loss of appetite, increased falls, and urinary incontinence. The classic burning sensation many younger people feel is often absent in the elderly due to age-related changes in sensation. (Source: Dutta, NIH, 2022) My mom experienced unusual fatigue and lower blood pressure.

Can a UTI cause dementia-like symptoms?

Yes. A UTI can cause symptoms that closely mimic dementia, including confusion, disorientation, and behavioral changes. These symptoms typically resolve once the infection is treated. If your loved one with dementia suddenly seems worse, a UTI is often the first thing to look into!

How do you prevent UTIs in elderly women?

Proper hygiene is the most important preventive measure. According to clinical guidelines published by the National Institutes of Health, most urinary infections come from bacteria that live around the rectum and anus — meaning wiping back to front brings potentially dangerous bacteria toward the bladder. Always wipe front to back. This is also recommended by Harvard Health as the first step in UTI prevention for older women. Staying hydrated helps flush bacteria from the urinary tract. Supplements like D-Mannose and cranberry extract may also help, according to a review published by the NIH — though consult your doctor before starting either.

How quickly can a UTI become dangerous in the elderly?

Very quickly. An untreated UTI in an elderly person can progress to a kidney infection or sepsis within 24 to 48 hours, particularly in someone with other underlying health conditions. According to a study in the Annals of Translational Medicine, 33% of functionally dependent geriatric patients with UTIs died during their hospital stay. Seeking treatment at the first sign of symptoms is critical.

Hot Take: What You Need to Know about UTIs in the Elderly

  • UTIs are a leading cause of death in the elderly

  • Be on the lookout for out-of-the-ordinary or exaggerated behavior as a symptom of UTIs in the elderly

  • Seek medical attention quickly (drop everything) to treat the UTI and prevent hospitalization or worse

  • Prevent UTIs with proper hygiene, including wiping from front to back

About the Author

3+ years ago, my mother's stroke turned me into a full-time caregiver, dealing with some elder-specific and some mom-specific conditions, including vascular dementia, Alzheimer's, congestive heart failure, and aortic stenosis. My caregiving journey didn't start there, though. In high school, I would skip class to take my dad to his doctor's appointments. In different ways, my parents have both been unwell throughout my life. I've put this site together to share a little knowledge, sprinkled with a few laughs. I hope it's helpful, and at least, I hope you know that you are not alone.
