Why Are the Elderly More at Risk for UTIs?
Decreased Urine Flow
An enlarged prostate in a male patient or kidney stones may block the flow of urine making it easier for bacteria to grow in the urinary tract.Â
Decreased Mobility
Having a difficult time traveling to and from the bathroom may cause older adults to hold their urine, increasing the risk of bacterial growth. In addition, a lack of flexibility may make it harder for seniors to wipe from front to back after going to the bathroom, making it more likely that bacteria will travel to the urethra.Â
Weakened Bladder Muscles
Bladder muscles become weaker as people age, and this can make it difficult to completely empty the bladder. This leaves residual urine in the bladder and makes it possible for bacteria to grow in the residual urine. Â
Fecal Incontinence
Bacteria found in the stool can cause urinary tract infections.Â
Catheters
Older adults who use catheters are more likely to develop infections, especially if nursing staff are not using sterile techniques and catheters are not changed often.Â
Weakened Immune Systems
As you age, your immune system becomes less effective at fighting the bacteria that cause UTIs.Â
Hormonal Changes
The drop in estrogen that occur in women after menopause can make infections more likely to occur.Â
Low Water Intake
Elderly patients are often prone to dehydration due to not drinking enough water. This can make the urine more concentrated and encourage bacteria growth.Â
