A kidney infection can become life-threatening if left untreated, potentially leading to death within days to weeks. The infection can cause kidney damage or kidney failure, and if bacteria from the kidney infection enter the bloodstream, it can cause sepsis—a medical emergency with a high risk of death. Sepsis can develop rapidly, sometimes within 12 to 24 hours of infection spreading, especially in vulnerable individuals. Acting quickly with proper medical treatment, mainly antibiotics, can prevent severe outcomes. Without treatment, a kidney infection can become fatal within 24 to 72 hours, particularly if it progresses to septic shock or kidney failure.
Kidney infections start often as a urinary tract infection and can escalate fast to severe complications if ignored. Symptoms like high fever, back pain, chills, and difficulty urinating require urgent medical attention. Early intervention drastically reduces the risk of death. High-risk individuals include older adults, pregnant women, people with diabetes or weakened immune systems, and those with urinary tract obstructions.
In summary, a kidney infection can kill you in as little as a day or two without treatment due to the risk of sepsis and organ failure. Immediate medical care is critical to prevent fatal outcomes. If you or someone experiences symptoms of a kidney infection, seek emergency care without delay.
