If you care for someone with dementia, urinary tract infections are probably not a new topic.
They come up again and again in caregiver conversations. Sudden confusion. A fall. Sleeping all day. Acting “off.” A frantic trip to urgent care. Sometimes an emergency room visit.
Because UTIs are so common in dementia caregiving, I invited Dr. Krieger, an emergency medicine physician, to talk openly about what she sees shift after shift in the ER.
And what she shared is important.
Not just about how serious UTIs can become, but about how differently they show up in older adults with dementia and what caregivers can realistically do to reduce risk.
Meet Dr. Krieger, Emergency Medicine Physician
Dr. Krieger trained at UC Irvine for medical school and completed her emergency medicine residency at UCLA. She now practices in Southern California, where she treats a high volume of older adults, including many living with dementia.
When I asked her how often she sees urinary tract infections in the emergency department, her answer was sobering.
“It’s actually more uncommon for me not to see a urinary tract infection on my shift than it is to see one,” she explained. “I’m talking about multiple UTIs in an eight to ten hour shift.”
Some are mild. Others are severe enough to require ICU admission.
And that range is exactly why early recognition matters.
Why UTIs Can Become Dangerous
Most urinary tract infections begin in the bladder. At that stage, they are localized. But if untreated, they can travel upward to the kidneys and eventually into the bloodstream.
When bacteria enter the bloodstream, the condition can become sepsis.
Sepsis is a life-threatening response to infection. Emergency departments operate with strict protocols to identify it early because rapid treatment with fluids and antibiotics significantly improves survival.
Dr. Krieger was clear that while ICU-level sepsis is not the majority of cases, UTIs are a common cause of severe infection in older adults.
But for caregivers of someone with dementia, the bigger challenge is often recognizing the infection early enough to avoid that progression.
Why the Emergency Room Is So Hard on Someone With Dementia
Dr. Krieger did not hesitate when I asked her about the ER environment for dementia patients.
“The emergency room is probably one of the worst places in the world for somebody with dementia,” she said.
Bright lights on around the clock. No natural light. Constant alarms. Multiple unfamiliar staff. Sleep disruption.
It is deeply disorienting.
Unfortunately, many dementia patients arrive there because their symptoms were not recognized earlier. And the reason for that is simple.
UTIs in dementia do not look typical.
Classic UTI Symptoms vs. Dementia Presentations
In younger adults, UTIs are obvious.
Burning with urination. Urinating frequently. Feeling unable to empty the bladder. Fever. Back pain if the kidneys are involved.
But in older adults, especially those with dementia, those classic signs may be completely absent.
“No fever at all,” Dr. Krieger emphasized. “I’ve seen septic elderly patients without a fever. Our immune systems just don’t mount the same response.”
Instead, families often bring in loved ones because:
They are suddenly more confused
They are weaker than usual
They have fallen
They are sleeping more
They are not eating or drinking
The most common early signal she sees is simply this: a sudden change from baseline.
And that distinction matters.
Dementia typically progresses gradually. When confusion escalates quickly over hours or days, something else may be happening.
A Critical Reminder for Caregivers
Dr. Krieger shared something that deserves to be repeated:
“If your family member with dementia has taken a sudden drop, don’t attribute it to their dementia suddenly progressing.”
Sudden change is often infection, dehydration, aspiration, or another medical issue.
Education is key. Many families only recognize the pattern after they have experienced it once before.
And unfortunately, that first experience can sometimes involve hospitalization.
When Should You Seek Care?
In an ideal world, you would call the primary care doctor.
In reality, appointments may not be available quickly.
Dr. Krieger recommends urgent care as a practical first step when symptoms are concerning but not severe. Urgent care centers can perform a urinalysis and send a urine culture.
She emphasized that urine culture is important because it identifies the exact bacteria involved. If the wrong antibiotic is prescribed, days can be lost before the medication is changed.
If symptoms are significant, or if your loved one appears seriously ill, the emergency department is appropriate.
And she offered this reassurance to caregivers:
“Don’t feel bad about coming in. That’s what we’re here for.”
Many families feel guilty about frequent visits. She wants caregivers to know they are not overreacting by seeking help when something feels wrong.
Why Early Treatment Matters Beyond Sepsis
There is another reason to treat UTIs early.
Caregivers often say something heartbreaking after a severe infection:
“She was never the same after that.”
Even when older adults recover medically, they may not fully regain their previous cognitive or functional baseline.
The more severe the illness, the harder it can be to bounce back.
Early intervention reduces that risk.
Why Some People Get Recurrent UTIs
Dr. Krieger broke this down into understandable categories.
Anatomy
Women are more prone to UTIs because their urethra is shorter. Bacteria have a shorter distance to travel.
After menopause, estrogen levels drop. Vaginal and urethral tissues become thinner and more fragile, increasing vulnerability.
Incomplete Bladder Emptying
Anything that prevents full bladder emptying allows urine to sit, creating a breeding ground for bacteria.
In men, enlarged prostate is common.
In women, prolapse after childbirth can contribute.
Dehydration
Hydration flushes bacteria out before they attach to the bladder wall.
Many dementia patients resist drinking fluids, despite caregivers’ best efforts.
“There’s only so much you can force your family member to drink,” Dr. Krieger said. “Don’t beat yourself up.”
Incontinence and Brief Use
For women using disposable briefs, moisture and bacteria sit directly near the urethra.
Dr. Krieger repeatedly saw patients in the ER who had been sitting in soiled briefs for extended periods, often due to behavioral resistance to changing or showering.
She kept asking herself: how can we reduce bacterial exposure in that high-risk zone?
Practical Prevention Strategies at Home
Dr. Krieger approaches prevention in two ways.
1. Prevent Bacteria From Reaching the Bladder
Gentle, consistent hygiene
Wiping front to back
Changing briefs promptly
Keeping the perineal area clean and dry
She also recommends discussing vaginal estrogen with a healthcare provider for postmenopausal women experiencing recurrent infections.
2. Flush Bacteria Out Before They Attach
Hydration is foundational.
Cranberry extract and D-mannose supplements may help prevent bacteria from adhering to the bladder wall. If you are considering either option, talk with your loved one’s medical provider first. Supplements are not regulated the same way medications are, and they can interact with existing conditions or prescriptions. If using cranberry, choose a high-concentration extract without added sugar, especially if diabetes is present.
For individuals with mechanical issues like prolapse or enlarged prostate, medical evaluation is important. Treatments that improve bladder emptying can significantly reduce infection risk, but they should always be guided by a healthcare professional.
The Product Dr. Krieger Created After Years in the ER
After years of seeing incontinent women repeatedly return with UTIs, Dr. Krieger developed a product called UraGuard.
She explained the concept simply.
If bacteria climb into the urethra from contaminated briefs, what if you could create a protective barrier directly under the urethral opening?
UraGuard is a thin insert placed inside a disposable brief. The central blue zone contains an embedded silver compound known for antimicrobial properties. The silver is within the material, not directly against the skin.
In laboratory testing comparing the shield to standard brief material, the surface beneath the shield showed 96 percent less bacterial growth after incubation.
It does not absorb urine. Urine passes through to the diaper. Its function is to reduce bacterial contact at the urethral opening.
The product was tested for up to eight hours of use and is designed specifically for women using briefs or pull-ups.
Dr. Krieger emphasized that it is not a replacement for hygiene or hydration. It is an additional layer of protection for women at higher risk due to incontinence.

The Most Important Takeaway
At the end of our conversation, Dr. Krieger said something I want every caregiver to hear:
“Sometimes you can do all of these things and they still get a urinary tract infection.”
Medicine is not perfect. Prevention is not perfect. Caregiving is not perfect.
You can encourage fluids. You can watch for sudden changes. You can support hygiene. You can explore prevention tools.
And infections may still happen.
That is not failure.
That is the reality of aging bodies and complex medical conditions.

You Do Not Have to Navigate This Alone
UTIs are one of the most common reasons caregivers feel panic. The sudden confusion. The guessing. The decision of whether to wait or go in.
Inside the Care Collective, we talk through real-life scenarios like this every week. When to monitor. When to act. How to reduce guilt around medical decisions. How to manage the emotional toll.
Because yes, UTIs are medical.
But the stress they cause caregivers is emotional.
And that deserves support too.
