Acute pyelonephritis is a severe kidney infection that can cause significant discomfort and lead to serious complications if not treated promptly. It is essential to recognize the signs and symptoms of this condition to seek appropriate medical care.

Here are the seven key symptoms of acute pyelonephritis:.

1. High Fever

One of the primary symptoms of acute pyelonephritis is a high fever. The body typically responds to infection by increasing the body temperature to help fight off the invading pathogens.

In the case of acute pyelonephritis, the fever can be quite severe, often exceeding 101 degrees Fahrenheit. The fever may be accompanied by chills, sweating, and general malaise.

2. Flank Pain

Flank pain, specifically on one side of the lower back, is a typical symptom of acute pyelonephritis. The infected kidney may become inflamed, causing significant discomfort in the area.

The pain is often described as a dull ache or a sharp stabbing sensation. It may worsen with movement or pressure applied to the affected side.

3. Painful Urination

Pain or discomfort during urination, also known as dysuria, is another common symptom of acute pyelonephritis. The inflammation in the kidney can cause irritation in the urinary tract, leading to painful urination.

This symptom is often accompanied by a sense of urgency and increased frequency of urination.

4. Blood in Urine

Hematuria, or blood in the urine, is a significant indicator of acute pyelonephritis. The infected kidney may bleed due to inflammation and damage to the renal tissues.

Blood in the urine may appear red, pink, or brown and can be visible to the naked eye or detected through laboratory tests.

5. Cloudy or Foul-Smelling Urine

In addition to blood, the urine of individuals with acute pyelonephritis may appear cloudy or have an unpleasant odor. The presence of pus or bacteria in the urine can give it a cloudy appearance, while the infection itself can cause a foul smell.

These changes are a result of the body’s immune response to the infection.

6. Fatigue and Weakness

Feeling unusually tired, fatigued, or weak is a symptom commonly associated with acute pyelonephritis. The infection places a significant burden on the body’s immune system, diverting energy and resources towards fighting the invading bacteria.

As a result, individuals with acute pyelonephritis often experience a lack of energy and a constant sense of tiredness.

7. Nausea and Vomiting

Acute pyelonephritis can disrupt the digestive system, leading to symptoms such as nausea and vomiting. The infection, combined with the body’s response to inflammation, can cause feelings of queasiness and an urge to vomit.

These symptoms may be more pronounced if the infection spreads to the bloodstream or affects other organs.

Conclusion

Recognizing the key symptoms of acute pyelonephritis is crucial for early diagnosis and appropriate treatment. If you experience any of the aforementioned symptoms, particularly in combination, it is essential to seek medical attention promptly.

Acute pyelonephritis can have severe consequences if left untreated, including kidney damage and bloodstream infections. With early intervention, the infection can be effectively treated with antibiotics and supportive care.
