What is a kidney infection?
Kidney infections, medically termed pyelonephritis, arise when bacteria infiltrate one or both kidneys. This typically occurs due to an ascending infection, where bacteria travel from the bladder or urethra upwards. As the kidneys play a vital role in filtering waste products and maintaining fluid balance in the body, these infections can pose a serious health threat if not addressed promptly. Understanding the causes, recognising the symptoms, and seeking timely treatment are crucial in preventing potential complications like kidney damage or sepsis (a life-threatening condition caused by the body's overwhelming response to an infection).What causes a kidney infection?
While various factors can contribute to kidney infections, the most common culprit is bacteria, particularly Escherichia coli (E. coli), which normally resides in the intestines. However, certain conditions can increase the risk of these bacteria entering and infecting the urinary tract:Urinary tract infections (UTIs) and bladder infections:
Untreated UTIs or bladder infections can pave the way for bacteria to ascend to the kidneys, leading to pyelonephritis.Female anatomy:
Women are more prone to kidney infections due to their shorter urethra, which allows bacteria easier access to the bladder and subsequently the kidneys.Urinary tract obstructions:
Any obstruction in the urinary tract, such as kidney stones or an enlarged prostate, can impede the normal flow of urine, creating a breeding ground for bacteria and increasing the risk of infection.Weakened immune system:
Individuals with compromised immune systems, due to chronic illnesses like diabetes or certain medications, are more susceptible to infections, including kidney infections.Medical devices:
Prolonged use of catheters or undergoing urinary tract procedures can introduce bacteria into the urinary system, elevating the risk of infection.

How do you know if you have a kidney infection?
Early detection of kidney infection is paramount for effective treatment and preventing complications. Familiarising yourself with the common symptoms can help you seek timely medical intervention:Frequent and painful urination:
A persistent urge to urinate, coupled with a burning sensation during urination, is a hallmark sign of a urinary tract infection, which may progress to a kidney infection if left untreated.Fever and chills:
The presence of fever, often accompanied by chills, suggests that the infection may have reached the kidneys. This warrants immediate medical attention.Lower back or side pain:
Pain in the lower back or side, typically below the ribs, is a characteristic symptom of kidney infection. The pain can be sharp and severe, and it's crucial to differentiate it from other types of back pain.Nausea and vomiting:
The body's inflammatory response to the infection can trigger nausea and vomiting in some individuals.Changes in urine:
The urine may appear cloudy, have a foul odour, or contain blood, indicating the presence of infection in the urinary tract.Distinguishing kidney pain from other types of pain
Kidney pain often presents differently from other types of abdominal or back pain. Here's how to distinguish it:- Location: Kidney pain is typically localised in the back, just below the ribcage, and often affects one side more than the other.
- Intensity: The pain is usually described as sharp and stabbing, although it can vary in intensity from person to person.
- Movement sensitivity: Unlike musculoskeletal pain, which may improve with changes in position or movement, kidney pain often persists or worsens with movement.
When to seek a doctor’s appointment?
It's crucial to understand that kidney infections rarely resolve independently. While some minor bladder infections may clear up on their own, kidney infections require antibiotic treatment to eradicate the bacteria and prevent serious complications like kidney damage or sepsis. If you suspect you have a kidney infection, consult a healthcare professional without delay.How is a kidney infection diagnosed?
Healthcare providers employ various methods to accurately diagnose a kidney infection:- Medical history and physical examination: A thorough review of your symptoms, medical history, and risk factors will be conducted.
- Urine tests: Urinalysis can detect the presence of bacteria, white blood cells (indicating infection), and blood in the urine.
- Blood tests: Blood tests can confirm the infection and assess kidney function, especially in severe cases.
- Imaging tests: In some cases, imaging studies like ultrasound or CT scans may be recommended to visualize the kidneys and identify any blockages or structural abnormalities.
How is a kidney infection treated?
The primary treatment for kidney infections is antibiotics. The course typically lasts one to two weeks, and it's imperative to complete the full course even if symptoms subside earlier to ensure complete eradication of the infection.- Antibiotics: The type of antibiotic prescribed will depend on the specific bacteria causing the infection and your overall health.
- Pain management: Over-the-counter pain relievers, such as ibuprofen or paracetamol, can help manage pain and discomfort. However, it's advisable to consult a doctor before taking any medication.
- Hydration: Drinking plenty of fluids, especially water, helps flush out bacteria from the urinary tract. Avoid caffeinated and alcoholic beverages as they can irritate the bladder.
How can I prevent a kidney infection: proactive measures for long-term health
Adopting simple yet effective preventive measures can significantly reduce your risk of developing kidney infections:- Hydration is key: Drinking an adequate amount of water throughout the day helps dilute urine and flush out bacteria from the urinary tract.
- Maintain good hygiene: Practice proper hygiene, including wiping from front to back after using the toilet, to prevent bacteria from entering the urethra. Avoid using harsh soaps or perfumed products in the genital area.
- Don't delay urination: Empty your bladder regularly and avoid holding urine for prolonged periods, as this can promote bacterial growth.
- Urinate after sexual intercourse: Urinating after sexual activity helps clear bacteria that may have entered the urethra.
When to seek medical attention: don't hesitate, act promptly
If you experience persistent symptoms of a UTI, such as frequent urination, burning sensation, or back pain, consult a doctor promptly. Seek immediate medical attention if you develop:- Severe pain
- High fever
- Confusion
- Signs of dehydration (e.g., decreased urination, dizziness)
Telehealth and kidney infections: a convenient option for initial assessment
Telehealth services can be helpful for initial assessment of kidney infection symptoms. Online doctors can evaluate your symptoms, order urine tests, and prescribe antibiotics if necessary. However, if your symptoms are severe or complex, an in-person visit may be recommended for a more comprehensive evaluation and management.Communicating with your doctor: key questions to ask
When discussing your concerns with a doctor, consider asking the following questions:- What are the potential causes of my symptoms?
- What tests will be conducted to confirm the diagnosis?
- What is the recommended duration of antibiotic treatment?
- Are there any lifestyle changes I can make to prevent future infections?
- How will I know if the infection has completely cleared?
In conclusion: prioritise your kidney health
Kidney infections, though potentially serious, are treatable conditions. Recognising the symptoms, seeking timely medical attention, and adhering to preventive measures can help safeguard your kidney health. Don't hesitate to reach out to a healthcare provider if you suspect you have a kidney infection. Early diagnosis and treatment are vital for preventing complications and ensuring a swift recovery.
