If you don't treat a urinary tract infection (UTI), the bacteria can travel up to your kidneys, causing a severe kidney infection (pyelonephritis) with fever, back pain, nausea, and vomiting, which can lead to permanent kidney damage or even life-threatening sepsis. While mild cases might resolve on their own, the risks of complications like kidney failure, sepsis, and issues in pregnancy (premature birth, low birth weight) are high, so prompt treatment with antibiotics is crucial.
Without treatment, symptoms of a UTI can last about a week. This can happen up to 40% of the time with a simple UTI. UTIs are more likely to go away on their own in adult women with no other health problems. But it's not always possible to predict if and when a UTI will resolve on its own.
Symptoms of a kidney infection might include:
It's rare, but UTIs — and the antibiotics used to treat them — can lead to diarrhea.
A UTI may be getting worse if your pain becomes sharper or spreads to your back or side, if you develop fever or chills, or if you notice blood in your urine. Nausea, vomiting, and fatigue are also warning signs.
Symptoms of a urinary tract infection (UTI)
pain or a burning sensation when peeing (dysuria) needing to pee more often than usual. needing to pee more often than usual during the night (nocturia) needing to pee suddenly or more urgently than usual.
Urinary tract infections (UTIs) are a leading cause of sepsis in hospitalized patients and present a wide spectrum of severity, from simple UTIs that respond well to outpatient antibiotics to complicated UTIs that can escalate to life-threatening urosepsis.
Symptoms of sepsis may include:
UTIs can trigger inflammation, which can disrupt neurotransmitter balance in the brain and lead to confusion. Pre-existing conditions. Older adults are more likely to have conditions such as dementia, Parkinson's disease or Alzheimer's disease. An infection like a UTI can worsen existing cognitive decline.
UTI Symptoms in Older Adults
Go to the emergency room for a UTI if you have a high fever, strong back or side pain, nausea, vomiting, or blood in your urine — but you feel alert and can get to the hospital safely without calling 911. Symptoms to watch for include: Persistent high fever (above 102°F), with chills and shaking.
Three key early warning signs of kidney problems are changes in urination (more or less frequent, especially at night), foamy or bloody urine, and persistent swelling, particularly around the eyes, feet, or ankles, indicating fluid retention. Other common signs include persistent fatigue, nausea, itching, and loss of appetite, as toxins build up when kidneys aren't filtering effectively.
Where do I feel kidney pain? You feel kidney pain near the middle of your back, just under your ribcage, on each side of your spine where your kidneys are. Your kidneys are part of the urinary tract, the organs that make and remove urine from the body.
Symptoms of sepsis from UTI may include fever, rapid heartbeat, confusion, and difficulty breathing. UTIs are more common in women than men and can be caused by various factors, such as poor hygiene, urinary tract abnormalities, or catheter use.
Myth: All UTIs must be treated with antibiotics.
Truth: Not all UTIs require antibiotics. Some people can have bacteria in their bladders but not experience any symptoms. This is called asymptomatic bacteriuria. In most cases, no treatment is necessary as the bacteria is not causing issues.
If your UTI goes untreated, it may progress into a more serious infection. “An untreated bladder infection can become a kidney or prostate infection. These infections are more serious, because they travel through the blood stream causing sepsis. Sepsis makes people very ill and can be critical,” Dr.
Don't drink alcohol or caffeine with a UTI
Alcohol can also weaken your immune system as you're trying to fight off the infection. Drinking coffee, tea, soda, energy drinks, and other caffeinated beverages when you have a UTI isn't a great idea either.
Agitation and restlessness may occur in seniors with a UTI because of the physical discomfort, but these symptoms may also result from confusion or delirium. You may feel jumpy, nervous, or on-edge, or you might have a hard time falling asleep or staying asleep.
While there's no miracle cure for a UTI, early treatment and self-care can make a big difference in how quickly you start to feel better.

Frequently Asked Questions About UTIs and Sepsis
Progression can occur over 48–72 hours or accelerate in vulnerable residents to within hours once systemic signs appear. Speed depends on host health, pathogen, catheter status, and how quickly staff recognize and treat the infection.
A UTI causes inflammation in the lining of your urinary tract. The inflammation may cause the following problems: Pain in your flank, abdomen, pelvic area or lower back. Pressure in the lower part of your pelvis.
In order to treat recurring UTIs, a urologist typically makes an attempt to identify the underlying reasons why this is happening. Testing may involve a cystoscopy, a CT scan of the urinary tract, and a urine culture.
The typical symptoms of a common (bladder) UTI include pain and/or burning while peeing, needing to pee more frequently, bloody or cloudy urine, and pressure in the lower abdomen. If the infection spreads to the kidneys, symptoms are acute. They can include: A high fever (above 101°)
