Why Are Seniors at High Risk for UTIs?

Patients over age 65, especially women, are at significantly increased risk for urinary tract infections, or UTIs,  than younger adults. These common infections are also potentially a much more severe health concern for older adults.  About 10% of women over age 65 and up to 30% of women over age 85 have had a UTI in the past year.

At Wynantskill Family Medicine in Wyantskill, NE, Ritchie J. Parrotta, DO, and Scott M. Parrotta, DO, prioritize educating their older patients about the risks, potential complications, and preventive strategies of UTIs. Here’s what they explain.

How aging changes the urinary system

As we age, our bodies undergo several changes that make it easier for bacteria to grow in the urinary tract. One major factor is that the muscles in the bladder and pelvic floor tend to weaken. This often leads to incomplete bladder emptying. When urine sits in the bladder for too long, it becomes a breeding ground for bacteria.

For women, the drop in estrogen after menopause changes the natural balance of bacteria in the vaginal area. This shift makes it easier for harmful bacteria to enter the urethra. 

For men, an enlarged prostate can squeeze the urethra and prevent the bladder from emptying fully.

Medical conditions and medication factors

Chronic health conditions common among older adults can further increase their risk. Diabetes is a significant factor because high blood sugar levels can show up in the urine, providing fuel for bacteria. Conditions like Alzheimer's disease or Parkinson's disease can make it difficult for seniors to maintain hygiene or recognize the urge to use the bathroom.

Medications can also be to blame. Some drugs cause the mouth and body to become dehydrated, which leads to less frequent urination. Regular urination is the body’s way of flushing out bacteria. If you aren't drinking enough water or going to the bathroom often, those bacteria stay put.

Recognizing unusual symptoms in seniors

In younger people, a UTI usually causes pain or burning. In seniors, the symptoms are often different and harder to spot. We frequently see patients who experience sudden confusion, agitation, or even falls rather than typical physical pain. This happens because the immune system responds differently as we age.

If you notice a loved one acting strangely or experiencing a sudden change in their mental state, it might not be dementia. It could be an infection. Catching these signs early is vital because untreated UTIs can lead to kidney infections or sepsis, which is a life-threatening reaction to infection. We use diagnostic tools to identify the bacteria and start the right treatment quickly.
