UTI is a common public health problem caused by a range of pathogens. An estimated 150 million global cases occur annually, with women at a higher risk from a particular type of urinary infection than men at least once in their lifetime.
Anatomy, hygiene, and other factors can play a significant role in developing an infection. Can dehydration cause UTI? It can. Dehydration has been identified to increase the likelihood of getting a UTI.
What is UTI?
Urinary tract infection or UTI is commonly caused by bacteria in any part of the urinary system. The bacteria often comes from the skin or rectum that enters the urethra, makes its way up, and grows to start an infection in the:
Kidney infections are serious when left untreated. Proper treatment requires a doctor’s visit early on.
How Does the Urinary Tract Work?
Here’s a quick overview of the urine production and elimination process to help you better understand where and how UTIs occur.
The urinary tract is a system that produces, stores and eliminates urine. Urine is produced by the kidneys, stored in the bladder, and eliminated through the urethra. The kidneys are two bean-shaped organs that filter waste from the blood to preserve chemical equilibrium in the body and produce urine. The urine flows from the kidneys through the ureters to the bladder, a sac that stores urine until it is eliminated through the urethra.
The urethra is a tube that carries urine from the bladder to the outside of the body. The one-way flow of urine is designed to prevent infections and deliver urine that usually contains only salts and waste products but does not contain bacteria. Urine, colloquially known as pee, is a suitable environment for growing bacteria.
There are several ways the bacteria can get into the urethra, such as wiping from back to front after urination or defecation for women, or sexual intercourse and use of contraceptives for both men and women increase the risk of a UTI.
Who is At Risk of UTI?
Adult women and men can get UTIs. However, it is more prevalent for the former between the two. Young children and infants can have UTIs, too.
UTI in Children
The peak incidence is between the ages of 1 and 3 years. Children under the age of 1 year have the highest hospitalization rate for UTI. The rate then decreases in older children and increases again in older adults over 65.
Women vs. Men Infections
UTIs are more common in young women, with the highest rates occurring in women aged 20-24 years, yet the incidence of UTIs increases with age in both sexes. In men, the incidence of UTI doubles every 10 years after age 50. In women over the age of 65, the incidence of UTI is five times higher than in men of the same age.
What are the Symptoms of a UTI (Urinary Tract Infection)?
UTI cases don’t usually present signs and symptoms, but when they manifest, SA Health enumerated the following:
- Stinging or burning sensation when passing urine
- There is much more frequent passing of urine than usual
- Constant urge to urinate but passing only drops or unable to do so
- Feeling the bladder is still full even after urination
- Wetting or incontinence – passing some urine before reaching the toilet

Children’s Symptoms
Symptoms may look a little different in kids as compared to grown-ups. They may experience a couple or all of the following:
- Fever
- Unexplained irritability
- Not willing to eat or less food intake
- Cloudy or foul-smelling urine
If you or your child have these symptoms, consult a GP, who may refer you to a urologist. Fortunately, there are many urology clinics in Adelaide.
Three Major Types of UTIs
Infections can affect any or several parts of the urinary tract, but the usual types are:
Bladder infection
Cystitis is the most common UTI, accounting for around 80% of all infections. It usually affects the bladder and is characterised by a burning sensation when urinating cloudy or bloody urine, and a feeling of urgency to urinate.
Urethra infection
Urethritis is an infection of the urethra, the tube that carries urine from the bladder to the outside of the body. It is usually caused by Escherichia coli (E. coli), Chlamydia, or gonorrhoea. Symptoms include pain when urinating, cloudy or bloody urine, and a burning sensation in the urethra.
Kidney infection
Pyelonephritis is a more severe type of UTI that affects the kidneys. E. coli, Klebsiella pneumoniae, or Pseudomonas aeruginosa usually cause it. Symptoms include fever, chills, nausea, vomiting, and pain in the lower back.
Now, What is Dehydration, and How Does It Cause UTI?
Dehydration is a lack of fluids and electrolytes in the body. Various factors, including heat exposure, strenuous physical activity, and insufficient water intake, can cause it. Dehydration occurs when the body loses more fluids than it takes in. When it happens, the body cannot function properly and may be unable to fight off infection.
While dehydration can occur at any age, dehydration is a particular concern for older Australians. This is because dehydration can cause UTIs, which are more common in older people. Dehydration can also cause other health problems, such as:
- constipation
- kidney stones
- Heatstroke.
Dehydration can lead to an increased risk of UTI for several reasons.
Less urine
First, dehydration causes your body to produce less urine. When you don’t urinate as often, there is more time for bacterial growth to occur in your urinary tract.
A more acidic environment
Second, dehydration can make your urine more concentrated and acidic. This environment is ideal for bacteria to thrive.
Decreased protection
Finally, dehydration can decrease the production of substances that fight infection. This makes it easier for bacteria to cause a disease, which is why dehydration is one of the leading risk factors for UTI.
What are the Signs of Dehydration?
In mild to moderate cases, the common signs are:
- Extreme thirst
- Dry mouth or dry skin
- Headache
- Decreased urination
- Increased body temperature
- Muscle and heat cramps
- Fatigue and lightheadedness
- Low blood pressure
- High heart rate
If the condition progresses, signs of severe dehydration include:
- No urination for several hours, or urine is very dark
- Confusion and irritability
- Sunken eyes
- Fainting or unconsciousness
- Fever and chills
- In infants and young children, sunken soft spots on top of the head
When your body doesn’t have enough fluids, it becomes unable to flush bacteria from your urinary tract. The different symptoms of dehydration that can lead to UTI are:
- Dark urine
- Fatigue
- Fever
- Headache
- Nausea and vomiting
- Muscle aches
Always Maintain Hydration
It is essential to maintain enough fluid intake to prevent dehydration, which can put the body at risk for infections and complications. There are many ways to do this daily.
- Drink plenty of fluids throughout the day, from water to cranberry juice.
- Avoid diuretics such as caffeine and alcohol.
- Eat foods high in water content, e.g., fruits and vegetables.
- Take breaks to cool down and drink plenty of water during physical activity.
- Check for dehydration symptoms regularly, such as thirst, dry mouth, fatigue, or dark urine.
First Aid for Dehydration in Adelaide
In severe cases of dehydration, which are already medical emergencies, carefully assess the signs and symptoms of your coworker, family member, or the person affected to know what first aid practices are needed. We’ve listed some helpful measures to stabilise the patient during or after calling the local Adelaide emergency hotline.
Remain Calm and Offer Reassurance
When experiencing symptoms, the patient can become panicky. Assist the person in sitting down and reassure them that it will be okay and that medical help is coming.
Start Hydrating
Fluids in the body are replenished. Give the patient small sips of an oral rehydration solution. If no solution is readily available, offer water. Note that juice or soda can worsen the situation.
Lower the Body Temperature
In hot weather or environments, remove the patient’s excess clothing or loosen clothing to promote heat loss. To lower the body temperature further, place ice packs around the neck, armpits, or groin area.
Monitor Vital Signs
First aid training courses in Adelaide teach business staff how to check a person’s respiration rate, heart rate, blood pressure, body temperature, and so on in emergencies like severe dehydration. This information is relayed to emergency responders and healthcare providers when they arrive.
In Conclusion
Dehydration increases the risk of getting a urinary tract infection. Keeping a hydrated body daily by drinking plenty of fluids and consuming supplements such as fruits and juices helps prevent UTIs and other diseases. Other measures, such as wearing cotton underwear and loose-fitting pants, may also reduce the risk. In severe cases, first aiders at the workplace or community can provide information and first aid services.
