How dangerous is kidney infection?

A kidney infection, also called pyelonephritis, can range in severity from mild to life-threatening. The severity depends on factors such as the underlying cause of the infection, the individual's overall health, and the promptness of treatment.

Mild kidney infection:

A mild kidney infection may cause symptoms such as fever, chills, back pain, and cloudy or foul-smelling urine. In most cases, a mild infection can be treated with antibiotics and rest, and it usually resolves without causing any lasting damage.

Moderate kidney infection:

A moderate kidney infection may cause more severe symptoms, including high fever, severe chills, intense flank pain, nausea, and vomiting. It may also lead to dehydration, electrolyte imbalances, and sepsis (a life-threatening infection of the bloodstream). Treatment typically involves intravenous antibiotics, fluids, and pain management.

Severe kidney infection:

A severe kidney infection can be a medical emergency and may require hospitalization. Symptoms can include high fever, chills, severe flank pain, nausea, vomiting, confusion, and decreased urine output. Sepsis and organ failure can develop rapidly, making timely diagnosis and treatment crucial. Treatment typically involves intensive antibiotic therapy, intravenous fluids, and supportive care to maintain vital functions.

In some cases, a kidney infection can lead to complications such as scarring of the kidneys, chronic kidney disease, and kidney failure. It's important to seek prompt medical attention if you suspect a kidney infection to ensure proper treatment and minimize the risk of serious complications.
