Urinary Tract Infections
Urinary tract infections, or UTIs, are a common infection that affect more women than men. Most often, they are treated quickly and effectively with antibiotics. Unfortunately, not all UTIs are treated quickly and some aren’t even identified, particularly in people who have limited or no sensation below the waist or who are unable to speak for themselves.
An untreated UTI may spread to the kidney, causing more pain and illness. It can also cause sepsis. The term urosepsis is usually used to describe sepsis caused by a UTI.
Sometimes incorrectly called blood poisoning, sepsis is the body’s often deadly response to infection or injury. Sepsis kills and disables millions and requires early suspicion and rapid treatment for survival. People shouldn’t die from a UTI, but if sepsis begins to take over and develops to severe sepsis and then to septic shock, this is exactly what can happen. More than half the cases of urosepsis among older adults are caused by a UTI.
Sepsis and septic shock can result from an infection anywhere in the body, such as pneumonia, influenza, or urinary tract infections. Worldwide, one-third of people who develop sepsis die. Many who do survive are left with life-changing effects, such as post-traumatic stress disorder (PTSD), chronic pain and fatigue, organ dysfunction (organs don’t work properly) and/or amputations.
What is a urinary tract infection?
A UTI is an infection in the urinary tract, which runs from your kidneys, through the ureters, the urinary bladder and out through the urethra. UTIs are very common and, in general, easy to treat.
A lower UTI, the more common type, affects the lower part of the urinary tract, the urethra and urinary bladder. Infection of the urethra is called urethritis and of the bladder is called cystitis. If the kidney is infected, called pyelonephritis, this is an upper UTI, as the kidney is the highest part of the urinary tract.
A UTI can be caused by bacteria (the most common type of infection) or a fungus.
How do you get a UTI?
The design of the human body makes it so it isn’t difficult to get a bacterial UTI, because the infection comes from outside, through the urethra. Bacteria in the genital area can enter the urethra and the urinary tract, either because wiping after going to the bathroom, sexual activity, or unsanitary conditions. Once the bacteria has entered the urethra, the body tries its best to fight it off, but sometimes the immune system can’t do this, the bacteria multiply, and cause the infection.
In the case of a fungal infection, usually the fungus gets to the urinary tract through the blood stream. Those who develop this type of infection are usually ill with a disease that has compromised their immune system, such as AIDS.
In general, women get more UTIs than do men and this increases with age. Statistics show that many women get more than one. Almost 20% of women who have had one UTI will go on to have a second. Of this 20%, 30% of those will have a third, and in turn, 80% of these women will have more.
In the early stages of a lower UTI, you may feel:
- Sudden and extreme urges to void (pass urine)
- Frequent urges to void
- Burning, irritation or pain as you void
- A feeling of not emptying your bladder completely
- A feeling of pressure in your abdomen or lower back
- Thick or cloudy urine – it may contain blood
As the infection progresses, you may experience:
- Pain in the lower flank, part of the back where your kidneys are located
- Nausea and vomiting
Seniors may not show any of these signs or they may be too subtle for someone else to notice. An added symptom among this age group is confusion. Often, if a senior’s behavior changes suddenly, they may have an undiagnosed UTI.
When caught early, it is usually quite easy to treat a bacterial UTI effectively. After confirming that you do have an infection (usually through a simple examination of a urine sample), you would be prescribed antibiotics to fight the particular bacteria causing the infection. You also would be encouraged to drink a lot of water, to help flush out the infection.
If your doctor suspects that the infection may have spread, you may be sent for additional tests, such as blood tests, scans of your kidneys or an ultrasound.
It is essential that you complete your full prescription, taking all the antibiotics you receive, even if you feel 100% again. Even with the symptoms gone, the bacteria will still be present for a while and you need those antibiotics to finish getting rid of them. If you do not finish your prescription, there is a very good chance that the bacteria that was left behind will grow again, causing another infection. And, they may become resistant to the antibiotics that you originally used.
To treat a fungal UTI, your doctor would prescribe anti-fungal medications. These, too, must be completely taken to ensure the infection has been dealt with.
UTIs can be prevented in almost all cases.
- When women wipe themselves after having a bowel movement, they must wipe from front to back, reducing the chances of stool touching the entrance of the urethra. The same thing must be done by caregivers if they are cleaning someone else.
- After having sex, clean your genital area as the act of sex could push bacteria into the urethra.
- If someone has a catheter, a tube that drains urine from the bladder, it is essential that inserting the catheter be done in as sterile or clean an environment as is possible. As well, the urethral area must be kept clean, particularly of stool. Urinary catheters should not stay inserted for longer than necessary.
If you have frequent UTIs, there are some steps you can take to try to reduce the number of infections you get. They include:
- Drinking plenty of water every day, to help flush out your urinary tract.
- Don’t hold your urine. Empty your bladder as frequently as is realistic and possible.
- For women, continue the wiping from front to back and cleaning well after sex.
- Also for women, some find that diaphragms increase their number of UTIs, so if you are using a diaphragm, you may want to discuss an alternate method of birth control with your healthcare provider.
